Description
The easiest way to show readings, menus and messages. The PCF8574 I2C backpack on the back cuts the wiring down to two data lines, leaving your other pins free for sensors.

- White characters on a blue LED backlight
- PCF8574 I2C adapter, pre-soldered
- I2C address 0x27 (some batches 0x3F)
- Contrast trimpot and backlight jumper on the adapter
- 5 V supply
Getting started
Connect VCC → 5 V, GND → GND, SDA → A4, SCL → A5 (UNO). Install the LiquidCrystal_I2C library. If the screen shows only blocks or nothing, turn the blue contrast trimpot on the back; if it still shows nothing, run an I2C scanner sketch to find the address.
