Description

Classic 16x2 character LCDs with the I2C controller built onto the board, so each one needs only four wires. Three displays with front bezels.

Highlights

• I2C on board. The PCF8574T sits on the display PCB itself, not on a stacked adapter, keeping the module 12mm thick.
• No soldering. The 4-pin header (VCC, GND, SDA, SCK) is fitted at the factory.
• Two signal pins. Only SDA and SCK, leaving the rest of your GPIO free.
• Three on one bus. The A0–A2 pads change the address from the default 0x27, so all three can share a bus.
• Finished look. Snap-on black bezels hide the PCB edge for panel mounting.

In the box

• 3 × 1602 I2C LCD display, 16x2 blue
• 3 × snap-on black front bezel
• 1 × mini screwdriver for the contrast trimmer
