The Raspberry Pi Pico is on the back side of this board

Prerequisites

• KiCad 6.0+
• load symbols and footprints. The schematic and PCB depend on the library located in /libs, which needs to be added before opening the schematics/pcb in KiCad:
  • symbols: KiCad -> Preferences -> Manage Symbol Libraries...,
  • footprints: KiCad -> Preferences -> Manage Footprint Libraries...
• PCB manufacturing: any manufacturer capable of 4-layer and 0.4mm vias -- pretty much any PCB shop
