Bitcrane
About the Bitcrane PCB
Bitcrane is an open source PCB design by skot, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 110 × 100 mm, with 70 components from 29 distinct parts.
Other key parts include the C2651882, C841192, C616741 and EMC2305. By type, the board carries 31 resistors, 20 capacitors, 10 connectors, 4 ICs, 2 inductors and 1 transistor.
From the project
a USB controlboard for Antminers
introducing the bitcrane. a quick tool to spit bytes at an Antminer hashboard over USB (and control fans & PSU).
- Updated the BOM (and some parts) to make this compatible with PCBA from jlcpcb.com. - Send them bitcrane BOM JLCPCB.csv and bitcrane-all-pos.csv from the Manufacturing Files folder. - JLCPCB Doesn't stock the EMC2305 (U4) and has a terrible price on the FT4232HQ (U1), so you should prolly assemble these yourself.
