Adafruit 3954 Neo Trellis RGB Driver PCB For 4x4 Keypad
Adafruit Silicone Elastomer 4x4 Keypad and Driver Board - Adafruit ADA3954, By popular request, Adafruit have upgraded their popular Trellis elastomer button kits to have a PCB with full colour NeoPixel support! No more single-colour LEDs, you can now have any colour you like under the fantastic rubbery button pads. 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. With the trusty seesaw I2C-to-anything chip, you don't even need to manage the NeoPixel driving. That's right! Both the button management and LED driving is completely handled for you all over plain I2C. With both Arduino/C++ and CircuitPython/Python library support, you can use these pads with any
and all microcontroller or computer boards. Perfect for your next cool interface, MIDI instrument, control panel.. . wherever could benefit from beautiful diffused colourful buttons. For fast connection to a single board, there's a JST-PH 4-pin connector installed that will give you both power and data access. It's Grove compatible (the cable fits, even though its not the exact same connector), or you can use a JST-PH 4 pin cable. 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. The elastomer button pad is not included, so be sure to pick one up! Adafruit
