Bitaxe is a fully open-source hardware Bitcoin ASIC miner. Ultra is the 3rd major revision of the Bitaxe that includes the BM1366 ASIC chip from Antminer S19XP. Supra is the 4th revision that includes a BM1368 ASIC Chip from Antminer S21. A 5V DC power supply with 2.1/5.5mm barrel jack connector is included with Bitaxe. US to EU plug adapter included with all overseas orders.

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

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/BM1368 from Bitmain.
  • Versatile: solo/pool mining, autotune power/heat/efficiency.

Features

  • ESP32-S3-WROOM-1 Wi-Fi microcontroller on board
  • TI TPS40305 buck regulator steps down the 5V input to power the BM1366/BM1368
  • Maxim DS4432U+ current DAC digitally adjusts the BM1366/BM1368 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
 

AxeSheath Enclosure for Bitaxe

  • Designed from the ground up, this 3D printed plastic case protects your Bitaxe  by fully enclosing its electronic components.
  • AxeSheath is made with PETG plastic that offers superior durability and heat resistance. 
  • Snap fit joints make it easy to install or remove, without the need for any tools or fasteners. 
  • The enclosure is vented on 4 sides to allow for sufficient airflow, even when overclocking. 
  • Perfectly sized openings for power jack, USB connection, and ESP32 antenna. 
  • Cradles and supports the OLED display

Comes with 14-day full refund/return Altair warranty. 

Setup Instructions

  1. Attach the display to Bitaxe PCB (skip this step if you purchased with AxeSheath)
  2. Plug Bitaxe into the included 5V power supply. Please do not plug any non-approved 12V power since that will permanently damage the device. 
  3. Bitaxe will now attempt to connect to a default network, which it will not find. To configure the Bitaxe use a WiFi capable device such as a Phone or Laptop and search for the new WiFi Access point Bitaxe_XXXX. Connect to the Bitaxe SSID and you should be prompted for or redirected to the AxeOS web portal. If this does not happen after you connect to the Bitaxe, open your browser and visit http://192.168.4.1
  4. When you see the AxeOS web portal click on the ‘settings’ button
  5. Configure the WiFi SSID and password for your local WiFi network (Note: Bitaxe is not compatible with 5Ghz Wifi, it only works with 2.4Ghz WiFi). Double check your WiFi SSID name and password before entering,  to prevent manual recovery later.
  6. Update the pool url, port and user to your preferred pool. We recommend ckpool or publicpool for solo mining. 
  7. Click Save, then click restart to apply the changes.
  8. Done! If everything is configured correctly your bitaxe will start mining. You can re-vist and reconfigure the Bitaxe on your local network by visiting the IP address displayed on the device. You can also press the ‘boot’ button on the device to enable the WiFi access point and connect to it directly at any time. Pressing the ‘boot’ button again will disable the access point.

Frequenty Asked Questions

This is a learning device aimed at makers, tinkerers and hardware enthusiasts. Low noise, Wifi Connectivity and the ability to run this without connecting to a computer make it an ideal home miner. Profitability will depend on many factors such as power cost, bitcoin price etc.

Yes it can be overclocked or underclocked. Overclocking voids warranty and you may need additional cooling to do it. Here are some overclocking results from a community member, that you can use as a reference. 

Temperature in 0-80°C range are OK. 

Mining efficiency drops with rising temperature, so ideally you want this temperature under 65C. 

The minimum payout on most bitcoin mining pools is too large for sub petahash mining operations. Bitaxe is better suited for lottery mining for a chance at winning 6.25 BTC block reward on solo mining pools like ckpool and kano pool.

While the odds of hitting the block lottery on a single chip ASIC miner are low, it happens more often than one might imagine. There are documented instances of people hitting a BTC block with comparable devices like the Gekkoscience Compac F. 

The display is plugged into the PCB and can come loose. If your display is not working, try pressing it down to see if that helps. You can also try opening the enclosure to reseat the display. If your display still does not work, you can purchase a replacement unit here https://www.amazon.com/gp/product/B08ZY4YBHL

Temps in the 40-65C range are ideal. Chip temperatures over 70C should be avoided and temperatures over 80C can permanently damage the device. 

Press the ‘Boot’ button and it will reactivate Bitaxe’s device Wi-Fi. You can then connect to this wifi network and enter your Wi-Fi credentials. 

If this doesn’t work, you can turn off the Wi-Fi network Bitaxe is trying to connect by turning off the Wi-Fi router, to break the reconnection loop. 

 

 

AxeSheath enclosure is made up of 2 sections, that snap fit together. It can be removed by prying the 2 pieces apart. Video below shows how this is done with a pencil. 

No, Bitaxe only works with 5V power input. 12V power will permanently damage the device.
