This PCB is the controller board for the TomatoCube HollowClock Lab Kit (iCE40 FPGA edition), built around the Lattice iCE40LP384 FPGA. It drives the HollowClock's 28BYJ-48 stepper motor to turn the clock hands, and includes an infrared (IR) receiver for remote control, two NeoPixels RGB lighting output, tactile buttons and LEDs. Users can explore digital logic and hardware design by writing and building their own Verilog with the open-source apio toolchain.
