Product description: I2C / SPI character LCD backpack - I2C / SPI converter for LCD display - STEMMA QT / Qwiic - Adafruit 292
I2C/SPI converter from Adafruit designed for LCD display . It works with any LCD display with a size from 8x1 to 20x4 characters and with a 16-pin connector located at the top of the module. The module does not support OLED displays . The use of this type of converter in the project facilitates the operation of the display and limits the number of microcontroller pins used to the SDL and SDA lines of the I2C interface. The board has a charging circuit from 3 V to 5 V, so the I2C / SPI character LCD backpack can also be used to control LCD displays operating at 5 V, even with 3 V power supply and logic.
I2C / SPI character LCD backpack - I2C / SPI converter for LCD display - STEMMA QT / Qwiic - Adafruit 292.
Product compatible with Arduino and CircuitPython/Python!
Also check the user guide prepared by the manufacturer.
The converter operates with a voltage in the range of 3 V to 5 V DC.
