This Raspberry Pi mining HAT is based on the BitAxe Ultra 1.3 (with BM1366) design.

Update: Miner is running stable 🥳

Changes to BitAxe Ultra

• powered by 12V and
• added TVS diode and fuses
• revised buck switching regulator circuit
• revised heatsink
• removed like DAC (only fixed 1.2V on PiAxe), current measurement, fan PWM controller, additional testpoints
• smallest components have 0805 size for easier manual assembly
• LM75 compatible temperature sensor under the heatsink

Installation

• add to /boot/config.txt:

dtoverlay=pwm

• enable serial and I2C via raspi-config

If you want to use Influx and Grafana you need docker too:

$ curl -sSL https://get.docker.com | sh

Python:

# install pip3
$ sudo apt install python3-pip

# install libraries
$ for lib in pyserial rpi_hardware_pwm smbus influxdb-client pytz; do pip3 install $lib; done

# install i2c-tools
$ sudo apt install i2c-tools
