Adafruit NeoTrellis RGB Driver PCB for 4x4 Keypad

Adafruit, MIT

By popular request, we've upgraded our popular Trellis elastomer button kits to now have a PCB with full color NeoPixel support! You heard that right, no more single-color LEDs, you can now have any color you like under the fantastic rubbery button pads we sell.

VIN
Power input for the NeoTrellis board, shown in the Adafruit NeoTrellis guide wiring table as VIN.
Type · power
GND
Ground reference for the NeoTrellis board, shown in the Adafruit guide wiring table as GND.
Type · ground
SDA
I2C data connection. The Adafruit guide maps SDA to I2C data.
Type · signal
SCL
I2C clock connection. The Adafruit guide maps SCL to I2C clock.
Type · signal
INT
Optional interrupt output. The Adafruit guide says INT can connect to a digital pin on the host microcontroller.
Type · signal
A0
I2C address solder jumper. The guide says address jumpers hard-code unique addresses for tiled boards.

Displays

Character LCDs, SPI TFTs, e-paper modules and larger capacitive-touch TFT panels solve different display jobs. Treat display class, interface, controller, resolution, touch, refresh behaviour, storage, voltage and mounting as separate swap checks.

Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.
