Bitaxe Ultra 205 + Orange Stand & 5v 4amp PSU + Black Edition Ultra Quiet Fan

Bitaxe is a fully open-source hardware Bitcoin ASIC miner. Ultra is the 3rd major revision of the Bitaxe that now includes the BM1366 ASIC chip from Antminer S19XP. A 5V DC power supply with 2.1/5.5mm barrel jack connector is included with Bitaxe Ultra.

Powered by the AxeOS, an open-source firmware that gives you full control over your mining. Change settings and monitor performance on a clean web-interface. 

  • 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.

  • 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.
