README

This project is unfinished and on hold until the supply of CM4 8GB improves
This is a Raspberry Pi CM4 carrier board optimized for being a bitcoin node.
It is heavily based on the official Raspberry Pi CM4 Carrier Board
[Still very much WIP. The schematic is mostly done, and the PCB layout is started. Needs a lot more work, and testing!]
features
- Uses the RPi CM4 (use the CM4108032 with 8GB RAM and 32GB eMMC storage)
- M.2 M-Key slot for NVMe SSD storage. (Need that 1TB+ for bitcoin core!)
- Powered by 20W PoE+
- Gigabit ethernet
- USB port for debugging

Questions
How big is the Bitcart PCB?
It measures 136.6 × 54.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bitcart use?
78 parts, built around the 74LVC1G07SE-7-MS, EMC2301-1-ACZL-TR, FOD817S and MDT320M01001. 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.
Where can I download the Bitcart KiCad files?
From the skot/bitcart-node repository on GitHub, at the commit this page was made from: the board is bitcart.kicad_pcb and its schematic CM4_GPIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bitcart design in my own project?
Its repository states no licence, so its author keeps all rights: ask skot before reusing the design.
