Overview

BitaxeNaja is an open-source printed circuit board by bitaxeorg, from the bitaxeorg/bitaxeNaja repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 6-layer board of 65 × 112 mm with 197 parts on 156 nets, routed with 1,057 tracks and 799 vias.

It is built around the ESP32-S3-WROOM-1-N8, TPSM861253RDXR and TPS546D24ARVFR, with the SN74AVC4T774PW and TC2030-IDC-NL among its other parts. Its parts include 85 capacitors, 41 resistors, 10 ICs, 6 connectors and 2 switches. It belongs with the ESP32 boards of this library.

BitaxeNaja is a dual BM1340 Open Source Bitcoin miner using esp-miner

The BM1340 used in this design is suspected to be a prototype version of the ASIC used in the Antminer S23 series miners.

It is still an untested prototype! Don't build this expecting it to work at all.

Questions

How big is the BitaxeNaja PCB?

It measures 65 × 112 mm and has 6 copper layers, 1.6 mm thick.

What parts does the BitaxeNaja use?

197 parts, built around the ESP32-S3-WROOM-1-N8, TPSM861253RDXR, TPS546D24ARVFR and SN74AVC4T774PW. 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 BitaxeNaja KiCad files?

From the bitaxeorg/bitaxeNaja repository on GitHub, at the commit this page was made from: the board is bitaxeNaja.kicad_pcb and its schematic ASIC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BitaxeNaja 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).
