These 4x4 button pad boards are fully tile-able and communicate over I2C. With 5 address pins, you've got the ability to connect up to 32 together in any arrangement you like.
You can tile up to 32 boards together by soldering them edge-to-edge and soldering closed the I2C address jumpers, then use one I2C connection for all tiled NeoTrellis boards!
Each order comes with one NeoTrellis board with seesaw chip and 16 NeoPixels already soldered in place. Elastomer button pad not included.
- Dimensions: 60mm x 60mm x 4mm
- This board/chip uses I2C 7-bit addresses between 0x2E to 0x4D selectable by soldering jumpers on the back of the board
