Goals​

  • Standalone: can mine directly to your pool over WiFi. No External computer needed.
  • Embedded: low cost, low maintenance, high availability, high reliability, low power.
  • ASIC: based on the very efficient BM1366 from Bitmain.
  • Versatile: solo/pool mining, autotune power/heat/efficiency.

Features​

  • ESP32-S3-WROOM-1 wifi microcontroller on board
  • TI TPS40305 buck regulator steps down the 5V input to power the BM1366
  • Maxim DS4432U+ current DAC digitally adjusts the BM1366 core voltage from 0.04V to 2.4V
  • TI INA260 power meter measures the input voltage and current of the miner
  • Microchip EMC2101 PWM controls the fan and monitors tach output. Measuring internal die temp isn’t working.
  • 0.91″ SSD1306 OLED I2C Display Module
