I do this stuff in my free time for my enjoyment. Since I like to share my joy in creating this with everyone I try my best to provide a working PCB and Firmware. I am in no way an electronics engineer and can give no guarantees that this stuff does not break or damage your hardware, computer, phone, or whatever you try to hook it up to. Be sure to take great care when inserting any real MOS SID chips into the board. While everything has been tested with real chips, this is in no way a guarantee that nothing could go wrong. Use of this board and firmware at your own risk! I am in no way responsible for your damaged hardware. That being said, have fun!

116 parts, built around the MT3608, MBR120, MMBT2222A and SJ1-3525N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the LouDnl/USBSID-Pico repository on GitHub, at the commit this page was made from: the board is hardware/USBSID-Pico-v1.3/USBSID-Pico-v1.3f.kicad_pcb and its schematic hardware/USBSID-Pico-v1.0/USBSID-Pico-v1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
