DescriptionI2C Module has an inbuilt PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. These modules are currently supplied with a default I2C address of either 0x27 or 0x3F. To determine which version you have checked the black I2C adaptor board on the underside of the module.
If there 3 sets of pads labeled A0, A1, & A2 then the default address will be 0x3F. If there are no pads the default address will be 0x27. The IIC/I2C/TWI/SPI Serial Interface Board Module has a contrast adjustment pot on the underside of the display. This may require adjusting for the screen to display text correctly.
- Operating Voltage: 5V
- Backlight and Contrast is adjusted by potentiometer
- Serial I2C control of LCD display using PCF8574
- Come with 2 IIC interfaces, which can be connected by Dupont Line or IIC dedicated cable
- Compatible for 16x2 LCD
- This is another great IIC/I2C/TWI/SPI Serial Interface
- With this I2C interface module, you will be able to realize data display via only 2 wires.
- Length × Width (mm) : 41.6 x 19.2
- Weight (gm) : 4
Integration with Arduino
Makes connections to lcd screens simple with only to wires.. The board is perfect for projects needing to clean up i/o.. Has on board potentiometer which is great
Works perfectly, reduces the number of pins used on the mcu. Fits directly on to the back of the LCD display. Libraries are available for Arduino.
Easy to install and worked as promess
Works well. You’ll have to solder it to the LCD so just make sure you’re aware. The pins are close together. Just FYI.
Though there is quite a few Arduino references to get this working with a 16x2 LCD, I found the CircuitPython references to be limited. After a couple of days of searching and trial and error, I got this working with my Itsy Bitsy M4 board! I plan to add a few LCDs to the I2C chain as well.
Leaves me with more io pins on the arduino for other things. As apposed to using all the data pins individually
Good soldering. Works as described.
I added these onto a 4 line 20 character display. No issues in soldering them and they worked perfectly.
Works as it should.
Good product. Satisfied.
