Hobbyists, electronic enthusiasts and makers may be interested to know that Adafruit has announced the arrival of the NeoTrellis RGB driver PCB for 4×4 keypad. The upgraded Trellis elastomer button kits have been released thanks to customer requests now allow you to have any colour you desire under the rubbery button pads. The previous version only allowed one colour.
Both the button management and LED driving is controlled over plain I2C. Offering 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…whatever could benefit from beautiful diffused colorful buttons. For fast connection to a single board, we include a JST-PH 4-pin connector that will give you power+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.”
