[SpiROSE] Oh My Schematic

Not a lot to talk about, except that Adrien and I finally began the schematics for the rotative base. This PCB is the one hosting the SoM, FPGA and power supplies. We also determined the exact signal count going from this PCB to the PCB hosting the LEDs and their drivers.

Speaking of power supplies, we’ll need beefy ones. As a worst-case calculation with extreme currents for the LEDs, a single color can eat up to 100mA. That’s 0.1 * 3 * 80 * 48 / 8 = 144A of current. The /8 comes from the 8-multiplexing we are doing with the LEDs.

This week: finishing the schematics and fixing OpenGL.
