A custom-designed microcontroller development board built around the Raspberry Pi RP2040, designed from scratch in KiCad.
Decided to build my own custom RP2040 board to learn hardware design. The RP2040 is awesome for this because it has incredible documentation.
I started by blocking out the schematic into logical chunks. The power supply needs to deliver both 3.3V and 1.1V, so I used an MCP1700 regulator and stacked up a dense bank of 0.1uF and 1uF decoupling capacitors to keep the power rails stable. For storage, I connected a 128Mb flash chip. I also integrated a USB-C connector and wired up a standard 12MHz crystal oscillator circuit to handle the clocking.
Moving from the schematic to the layout sort of tricky but we got there.
Hopefully everything runs
