13 best bread boards

User questions & answers

Question:	what is the spacing of the holes in the breadboard? 0.10" or 2.0mm
Answer:	I measured the boards I received, and the holes do NOT appear to be on 0.10" centers. I don't know what they are. They don't line up with 0.10" solder protoboards I have.
Question:	Does the black ink that shows column letters and row numbers smudge or rub off easily
Answer:	No, the ink seems to be pretty permanent. At least so far :)
Question:	can the power bus be removed from the rest of the breadboard
Answer:	Yes, both sides can be removed although cutting through the adhesive backing and adhesive can be a bit of a pain. You also have to remember to clear the space where the "ears" are so they slide apart easily.
Question:	Is the thru hole spacing sized for standard DIP packages
Answer:	Yes.
Question:	Does it matter that the caps in my tv are blue amd not black
Answer:	shouldn't matter as long as capacity (uF) is the same and the voltage (V) is >= to the caps you have. I think this brand is supposed to be pretty good quality.
Question:	So how do you use the then i do have a tv that is kind of broken that i could use them for but i thought i was buying them for a capacitor for my car
Answer:	This item are standard capacitors, not super/ultra capacitors. My use case was to solder all these capacitors together to smooth out the 12 volt output from my rectified landscape lighting style power transformer I use for my refrigerators (12/24 volt RV/sleeper truck compressor type). If you have a power source that you feel doesn't give you smooth enough DC electricity, splice these into the circuit and off you go. Just don't exceed the 25 volt rating, or you'll have some firecrackers instead.
Question:	Can i use this cap for dc volt
Answer:	Electrolyte capacitor are designed to be use only in D.C., if it get connected to A. C. it will burst open.
Question:	Can you tell me how tall they are
Answer:	13x20mm/0.51x0.79 inch

What is breadboard？

Breadboard is a solderless device for temporary prototype with electronics and test circuit designs. Most electronic components in electronic circuits can be interconnected by inserting their leads or terminals into the holes and then making connections through wires where appropriate.

The breadboard has strips of metal underneath the board and connect the holes on the top of the board. Note that the top and bottom rows of holes are connected horizontally and split in the middle while the remaining holes are connected vertically.

The Breadboards Can be Spliced According to the Unit, the Structure is Clear in Color.

The Breadboards is 2-Sided Peelable Adhesive Tape，Easy to Stick on the Prototype Shield，Suitable for Line Prototype Design.

Product features

The Breadboard Power Supply has two power modes:

1) M/M USB Power Cable（included in this kit）;

2) 9V 1A DC Adapter（Not included in this kit）.

Jumper Wires

Jumper wires can be used for pin extension of the experiment board, adding experimental items, and the like. It can be connected very securely to the pins, eliminating the need for soldering and allowing quick circuit testing.

Our kit includes 65pcs male to male jumper wires, 20pcs male to female dupont wires, and 140pcs solderless jumper wires. which are completely adequate for various experiments.

IC 74HC595

The 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs. It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays. "Three-state" refers to the fact that you can set the output pins as either high, low or "high impedance." With data latching, the instant output will not be affected during the shifting; with data output, you can cascade 74HC595s more easily.

IC 4N35

The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.

Buzzer

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

To identify them, if you apply a DC voltage to them and it buzzes, it's an active.As far as commands go if you want to control the pitch, you would need a passive buzzer.

PN2222 NPN Transistor

The PN2222 can be used as a switch that use a little current from the R3 digital output to control the much bigger current of the motor. Because the small DC motor is use more power than an R3 digital output can handle directly.

1N4007 Diode

1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible.

Electrolytic Capacitor

Electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal.

Ceramic Capacitor

Ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

User questions & answers

Question:	can these jumpers be connected to GPIO pins of raspberry board
Answer:	I noticed this too! The full size dimensions seem like queen size measurements. It doesn’t make sense
Question:	Can you connect two or more breadboards together to use
Answer:	At the middle tip it is 55.5" tall at the top point.
Question:	What is the wire made of
Answer:	I brought this headboard and frame when I first got it there was one bed bug we killed it. Then I kept seeing one bed bugs here and there. When the temperature dropped here in miami they came out bed bugs everywhere on my bed took the frame apart and they were really coming out. I wish I could post the pictures on here. And before anyone comments I moved in to a brand new apartment and brought everything brand new i moved in with nothing. Some of y'all may have gotta lucky but some of us got bed bugs. Not only was 2020 full of surprises it was full of bed bugs too so No don't buy this bed or it will be at your own risk.

User questions & answers

Question:	what is the max volts/watts/current that can be passed through the board
Answer:	As long as your bed frame has holes in it this headboard should work. It has several different holes, so you can customize how high or low the padded back is. I have mine attached to a basic Hollywood frame. It does NOT come with the screws to attach it though. You will have to supply those.
Question:	Can you cut the boards apart? That is, one board cut into 3 pieces for three independent projects
Answer:	I attached the headboard directly to the wall. Looks great!
Question:	Will M2 size standoffs fit in these mounting holes? They measure very close to 2mm
Answer:	No. For mine, I bought 4 sets of bolt, nut and washer from Home depot. Carriage bolt 5/6 x 1-1/2. Code AHA. Nut: ABC, washer: ABB.
Question:	Are electrical connections made between holes in a pattern similar to those on a solderless breadboard? Or is each hole electrically isolated
Answer:	I have no idea, but we have had this bed frame for 2 months, it is in my daughters room , she weighs 30lbs, and I or my husband sleep in the bed with her so 230lbs it holds. Both my kids jump on it all the time and it has held up great!

User questions & answers

Question:	What is the max Amp I can use with this? In other words what is the power dissipation
Answer:	These are 26 or 28 AWG wire for bread boarding small signal components. They aren't intended for heavy current loads. They will probably carry 8 to 10 AMP before they fuse or burn open. The plug-in bread board connections will not handle that level of current very well. Power dissipation is not a parameter most engineers would be concerned about with this size of wire. These jumpers are for test wiring low current and logic level circuits. They do not make effective fuses.
Question:	Are these wires tinned for soldering on circuit breadboards
Answer:	They appear to be tinned. Just to be sure I tried a quick test with solder and they wet easily. These are normally used with the push in breadboards that are not soldered. They work very well for this. The connections are solid and reliable. The coating on the wires is important in this application. Bare copper wires are not reliable.

Product features

74HC595

At sometime or another you may run out of pins on your UNO board and need to extend it with shift registers. This example is based on the 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more.

4N35

The 4N35 is an optocoupler for general purpose application. It consists of gallium arsenide infrared LED and a silicon NPN phototransistor. When the input signal is applied to the LED in the input terminal, the LED lights up. After receiving the light signal, the light receiver then converts it into electrical signal and outputs the signal directly or after amplifying it into a standard digital level. Thus, the transition and transmission of electricity-light-electricity is completed. Since light is the media of the transmission, meaning the input terminal and the output one are isolated electrically, this process is also be known as electrical isolation.

PN2222 NPN Transistor

The small DC motor, is likely to use more power than an UNO digital output can handle directly. If we tried to connect the motor straight to an UNO pin, there is a good chance that it could damage the UNO. A small transistor like the PN2222 can be used as a switch that uses just a little current from the UNO digital output to control the much bigger current of the motor. The transistor has three leads. Most of the electricity flows from the Collector to the Emitter, but this will only happen if a small amount is flowing into the Base connection. This small current is supplied by the UNO digital output.

Electrolytic Capacitor

An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. The benefit of large capacitance in electrolytic capacitors comes with several drawbacks as well. Among these drawbacks are large leakage currents, value tolerances, equivalent series resistance and a limited lifetime.

Ceramic Capacitor

A ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

1N4007 Diode

A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible. The power dissipation of this diode is 3W. Applications of Diode: ● Can be used to prevent reverse polarity problem ● Half Wave and Full Wave rectifiers ● Used as a protection device ● Current flow regulators
