    Thomas Ruecker there's an STM32F070 on it and the drive circuitry is mainly a high-power version of the venerable 74HC595 for the columns and a Darlington array for the rows. The 595 is hooked up to the SPI bus and the Darlingtons are driven by GPIOs. The software is basically continuously scanning out the columns through SPI while selecting the row through its GPIO.

    The interesting bit is, however, that the tiles are interconnected through a UART and communicate with each other about dots leaving/entering.

    It's eventually supposed to run a distributed "Game of Life" on each of the tiles.
