Soldered Inputronic-GRID MicroPython Library

Note: this board is not yet released.

The Inputronic GRID is a 4x4 button + LED pad. It communicates over I2C (default address 0x30) with an onboard ATtiny microcontroller, which scans the 16 buttons and drives 16 individually-addressable RGB LEDs (one per button). Buttons can be read individually, by grid position, or all at once as a 16-bit bitmask; LEDs can be set individually, as a batch by bitmask, or all at once, with adjustable brightness. The I2C address is field-changeable and persisted to EEPROM, for daisy-chaining multiple GRID boards.

How to install
