They are 5V tolerant and perfect for your Arduino or other projects. These LCDs have been fitted with the adaptor and a PCF8574 I2C backpack interface, allowing you to use these on the I2C bus without any soldering - just plug and play to the four wires on thre backpack. We may send one of two versions of this device - the difference is the controller IC. If you have the PCF8574T. the default I2C bus address is 0x27. If you have the PCF8574AT the default I2C bus address is 0x3F. A jumper on the back controls power to the backlight, and a contrast potentiometer is also fitted. No soldering is required, modules are fully assembled. Click here for packs of five.
