The familiar 16 x 2 character LCD with a PCF8574T I2C backpack already soldered to the back, so it needs four wires - VCC, GND, SDA, SCL - instead of the usual sixteen. Default I2C address is 0x27, and the A0-A2 solder pads move it if something else on the bus clashes. A trimmer on the backpack sets contrast and a jumper switches the backlight. Runs on 5V, and comes with either a blue or a yellow-green backlight.
