Detailed overview

The NerdOctaxe is a fully open-source Bitcoin ASIC miner built with 8× BM1370 chips from the Antminer S21 Pro. It delivers up to ~12 TH/s with an efficiency of around ~15.8 W/TH, powered by a standard 12 V / 20 A supply.

Firmware + dashboard

Runs a dedicated fork of ESP-Miner (same foundation as NerdQaxe++ / NerdAxe) adapted for the LILYGO T-Display S3. On top, it integrates AxeOS for a clean web dashboard: config, pool management, and full monitoring.
