Product description

Description:



As we know, the CD1602 is an industrial character LCD that can display 16x02 or 32 characters at the same time. 



The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage,  that is, the graphic can be displayed.



In general, the 1602 uses a standard 16-pin interface, and our display module is a module that provides I2C functionality.



I²C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted.



It can be operated as long as it supports the I2C development board. For example, the common Arduino, raspberry pi, Stm32 and so on.



Package Includes:



2 x Blue backlight I2C LCD1602(1602 Serial LCD Module Display

8 x Jump wire

User questions & answers

Question:	is there any data sheets that show the size of the unit
Answer:	I can't find a ilive radio that is made for auto use. Maybe l could just tape the ilive boombox to my head?
Question:	any way to load message when power is appied? Is there any internal memory
Answer:	Making an educated guess, it's a 12v device, description claims it puts out up to 15 watts. So current usage should be around 1.25A @ Peak maybe a little more for losses or maybe a little less from over advertising power.
Question:	Where is the correct arduino library for this product? there are many on the internet. if not provided i will have to return
Answer:	If you mean for switching channels I don't think so.

Product description

Introduction：

As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller.

Therefore, LCD1602 with an I2C port is developed to solve the problem. It is also simple to handle. It has only two bidirectional data lines, a serial data line and a serial clock one.



How to wire:

GND—GND; VCC—VCC; SDA—A4; SCL—A5



Features:

Voltage: 5V DC

LCD display type: Characters

Module dimension: 80mm x 35mm x 11mm



Data：

1602 standard 16-pin interface, including:

Pin 1: VSS is the ground power.

2 feet: VDD then 5V positive power supply.

3 feet: V0 LCD contrast adjustment end, then the positive power supply when the contrast is the weakest, the highest contrast when grounded power, the contrast is too high will have a "ghosting", when used by a 10K potentiometer to adjust the contrast.

4 feet: RS for the register selection, high-level data register selection, low-level instruction register selection.

5 feet: R / W for the read and write signal lines, high-level read operation, low-level write operation.

6th foot: E end is enable end, when E end jumps from high level to low level, the liquid crystal module carries out the order.

7 ~ 14 feet: D0 ~ D7 for the 8-bit bidirectional data lines.

15 feet: the positive power supply backlight

16th foot: backlight power negative



Packing included:

2pcs 1602 16x2 LCD Display Module

Question:	Does this work with the serial hitachi hd44780 interface
Answer:	Looking at the instructions, I am not seeing that it can be controlled by a handlebar/thumb control.
Question:	Is this readable in daylight
Answer:	To the best of my knowledge no! It had a loud option but no AVR. I've looked extensively for it and can't find it. Only down fall I've noticed so far. All the other functions and original hand controls work well. Diffinetlybmore pro than con on this unit. Works much better than the OE Harmon Kardon Junk Harley installed.

User questions & answers

Question:	Can i use this with an stm32f4 type microcontroller
Answer:	I downloaded the JBL Connect app yesterday and walked through the tutorial. For JBL Connector to work you need to press the Connect button on each speaker to pair them. There is no Connect button on the JBL Horizon. I would guess the answer to your question is no. Also I unfortunately don't have another JBL Connect product that could pair so I can't be certain.
Question:	Do these come with an I2C backpack? I just ordered some of these and they came with no backpack in the package
Answer:	Yes, it has 2 settings: Weekday and Weekend. This is by far the coolest alarm clock on the market! We have 4 now! The white is especially nice...
Question:	Has anyone run this display on 3.3 volts successfully? I'd like to use it on an 8266-12E to display the ip address
Answer:	The instructions say to snooze the alarm with the snooze button and shut off the alarm with the smaller button behind the snooze button. When I set the alarm to go off with the radio , I could snooze the alarm but I couldn't shut off the alarm as they've instructed. I had to return it. Everything else worked fine except for shutting off the alarm when it was set to the radio.
Question:	It it possible to change the address of the lcd to have multiple lcd on the same bus
Answer:	Mine has the same problem 76-90MHz. This is the FM broadcast band for Japan so I am guessing the clocks has mistakenly received Japanese firmware. I will returning it with the hope my replacement is ok.

User questions & answers

Question:	is the I2C address setable to 4E
Answer:	I know this is an old question, but REALLY, clearly states set of (2) not (2) set or complete sets, an individual component speaker is made up of a woofer, a tweeter, and a crossover, which together counts as one speaker, and in some rare cases their may be a 3 way crossover with a midrange included, still the group is counted as (1) speaker and normally there sold in pairs, like the majority of car speakers, so you get that set up for your left channel/side of vehicle and one for your right channel/side of vehicle, a component set-up is what you normally see in quality home audio systems, and paired with one or more subwoofers is the best way to obtain high quality sound in your car/truck/suv/rv/boat.
Question:	I do not see the spec, should vcc be 5 vdc or 3.3 vdc to power this device
Answer:	Theres flat mounting and 45 degree angled tweeter mounts included
Question:	I am trying to get this to work with a teensy 4.1. the teensy does not recognize it at all. i have not tried with a nano (yet). any cues
Answer:	It has HD FM Radio and AM radio. It does not have satellite. However, you can connect your phone directly and play any app from your phone directly to the system.

User questions & answers

Question:	The description says ili9481 but the specs say hx8357c. what will i receive if ordered
Answer:	No. The HiLetgo website has the same product information as the text here at Amazon. This isn't good because some features of these displays do vary from manufacturer to manufacturer. This is very irritating because we need to know things like whether a resistor is included on the LED power line or not and how much power it draws. Yes, you could use some other manufacturer's information but then you are forced to assume that this one is the same. Thumbs down to HiLetgo for this.
Question:	This board doesn't seem to have the rdx signal to allow a register read. is there any way to put it into sleep or deep standby without the rdx pin
Answer:	Yes, here is a link to the specs: https://www.openhacks.com/uploadsproductos/eone-1602a1.pdf Section 4 has the dimensions in millimeters. Cheers, Mike
Question:	How do I connect other sensors/buttons to the Mega if this shield covers the entire Mega board
Answer:	You need something to drive it like an Arduino uno. then you just program it.
Question:	Does anyone have suggestions how to connect other things to the Arduino Mega 2560 when this display sheild? is attached
Answer:	It appears the libraries are already installed in the IDE. I used LCD.h and LiquidCrystal_I2C.h with an address of 0x27

User questions & answers

Question:	Does it work with the raspberry pi 3 model b
Answer:	The short answer is no. The display is SPI but an I2c module is attached and connected through header pins which you would have to remove drive via SPI.
Question:	it works like a monitor
Answer:	I found mine to be 0x27
Question:	can i power it with a usb battery pack? basically, i want to connect it to my DSLR as an ext monitor
Answer:	I measured about 44-45 mA with a DMM in the display Vcc line. However, it is a digital load that may fluctuate faster than the DMM can read it. It doesn't seem very power hungry. A set of 8 old 2200 mAh niMH batteries runs this display, an Arduino UNO, a DS3231 RTC, and a PMS5003 AQI sensor for a long time. I don't know how long, but more than I need at one time! In a few weeks of use, I have found absolutely nothing to dislike about this display, and much to like, especially how well it works! Just be sure to use the PCF8574.h library. I tried other libraries with frustrating results.
Question:	Will this display hdmi input without any raspi/usb connection? can i use this as a simple hdmi monitor without touch
Answer:	This device will work with Arduino but it has an I2C interface so you don't use the LiquidCrystal library. You have to use something like the LiquidCrystal_PCF8574 library. There are several other libraries that support LCD displays with I2C interfaces but the one I have used is the above and it works fine.
