README
README.mdbitaxeAva miner with quad Canaan A3197 ASICs
It is still an untested prototype! Don't build this expecting it to work yet.
- Open Hardware License; Real Open Source.
- KiCAD design files.
- Four Canaan A3197 ASICs powered in series
- Each ASIC is nominally 0.33V and 440 GH/s
- 11-13V XT30 input voltage
- TPS546D24S single-phase voltage regulator tuned for 2.4V output @ 30A
- The voltage regulator backside power plane is exposed to hopefully thermally bond it with the main heatsink.
- TPS546D24 backside busbar to cool the voltage regulator from the main heatsink.
- Fan controlled from the ESP32
- ESP32S3 for esp-miner support.
- Display moved off the main board. Should support the bonanzaDisplay
- Gerbers not provided to discourage side hacks and AliEx slop. HMU if you need help generating gerbers with KiCad.

Questions
How big is the BitaxeAva PCB?
It measures 76 × 101 mm and has 6 copper layers, 1.6 mm thick.
What parts does the BitaxeAva use?
162 parts, built around the ESP32-S3-WROOM-1-N8, TPS546D24SRVFR, SN74AXC4T774PW and STHW4-DU-HN050206. 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 BitaxeAva KiCad files?
From the bitaxeorg/bitaxeAva repository on GitHub, at the commit this page was made from: the board is bitaxeAva.kicad_pcb and its schematic ASIC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BitaxeAva design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
