Bitaxe 650 'Gamma Duo'

What is this?

Gamma Duo is a revision of the Bitaxe Gamma that reuses low-performing chips from the S21 lineup. Instead of discarding underperforming chips, this board puts them to work. With this board we make use of every available chip.

🛠️ Hardware

• The BM1370 is an undocumented SHA256 mining ASIC from Bitmain, used in the Antminer S21 lineup
• Bitmain claims the BM1370 has 15 J/TH efficiency
• The BM1370 has a similar footprint and pinout to the BM1368 used in previous Bitaxe models

Software

1. Building your Software

   • You can build your own binary files from the source code. For more details follow this Build-Guide.

2. Using a prebuild

   • Every Bitaxe is controlled by the open source ESP-Miner software. It features a WebUI for user-friendly usage and controllability.
   • In this repository you will also find a releases page that will contain prebuild binary files to flash to your Bitaxe using the Bitaxetool created by johnny9

3. Flashing Process

   • The ESP-Miner Software can be flashed via a USB cable onto the Bitaxe. Therefore you need to follow the initial Guide in the repository.
