This article provides a comprehensive Bitaxe how to FAQ guide. It covers everything you need to know to get started and optimize your bitcoin mining experience. You’ll learn what a Bitaxe is and how it works, including its technical process of hashing to mine Bitcoin. The guide details how to set up a Bitaxe, configure it for solo mining with an Umbrel node, and build one from scratch if you’re tech-savvy. It also explains updating firmware via the web UI or GitHub web flasher, resetting or factory resetting the device, and overclocking a Bitaxe for better performance. Finally, it offers insights on where to purchase a Bitaxe, ensuring you have all the information to mine Bitcoin effectively and independently at home.
What is a Bitaxe?+
A Bitaxe is a small open-source device for mining Bitcoin, perfect for home miners. While not the smallest Bitcoin miner, it’s compact and ideal for desks, bookshelves, and even mobile mining on the go. The Bitaxe is easy to use, connecting with Wi-Fi to mine Bitcoin. Models like the Bitaxe Gamma let you join the Bitcoin network and have fun learning about mining from home.
How does a Bitaxe work?+
A Bitaxe mines Bitcoin by performing random number generation to create new blocks. The device performs SHA-256 algorithm hashing on a block header, adjusting a variable called a nonce to produce a specific number that meets Bitcoin’s strict rules. If successful, the block is added to the blockchain, earning about 3.125 BTC plus transaction fees. The Bitaxe is a standalone miner, which means it connects over Wi-Fi, and uses a small 5-volt DC or 12-volt DC power supply for its main power source.
Bitaxe is primarily used for bitcoin mining but has the ability to mine any cryptocurrency utilizing the SHA-256 algorithm. These coins include Bitcoin Cash, Bitcoin SV, DigiByte, Namecoin, Peercoin, PRIZM, Litecoin Cash, Hathor.
How to set up a Bitaxe?+
To set up a Bitaxe home miner: 1) Plug the power supply in. 2) using your phone or computer, connect to the device's Wi-Fi SSID, named Bitaxe_XXXX. 3) Once you're in AxeOS, select your home Wi-Fi, and put in your Wi-Fi password. Hit save, then hit reset. Once the device reboots, it will display an IP address on the OLED screen after a few seconds. 4) On your phone or computer, open your browser, while on the same Wi-Fi network, and enter the device's IP address. 5) Once back in AxeOS, navigate to settings and enter a valid on-chain Bitcoin wallet address under the primary and fallback Stratum User fields. 6) Hit save and restart again then check the AxeOS dashboard to see your device mining. See the full guide on How to setup a Bitaxe below.
To solo mine with a Bitaxe, you’ll need to run a bitcoin node, like Umbrel's plug and play home server, or a 16GB Raspberry Pie flashed with UmbrelOS. Solo mining points your miners hashpower to your personal server's setup, unlike a lottery miner which shares a node's infrastructure with other miners, otherwise known as a 'solo mining pool'. 1) Plug in your Umbrel server. 2) Access the Umbrel dashboard by typing umbrel.local into the browser of your phone or computer, (while on the same local network). 3) Go through the simple setup process, then navigate to the Umbrel App Store, install Bitcoin Core or Knots and sync the bitcoin blockchain (this may take up to 3 days). 4) After the bitcoin blockchain successfully syncs, install Public Pool to obtain the Stratum URL and port number for mining. 5) Set up your Bitaxe using the Stratum URL and port number. 6) Navigate back to AxeOS, save, restart, and verify your device is mining on the Public Pool dashboard.
How to build a Bitaxe miner?+
Building a Bitaxe miner takes technical skills. You’ll need to: 1) Get components like a ASIC chip, an ESP32-S3 controller, a printed circuit board (PCB), and many small electronic components on the Bitaxe BOM (bill of material). 2) Solder them together carefully, following a detailed guide. 3) Load firmware onto the controller. 4) Add thermal paste on the ASIC, a heatsink, and a fan. It’s a fun project if you like electronics, but most people prefer a ready-made Bitaxe to start mining easily at home.
How to update Bitaxe firmware?+
Optimize Bitcoin mining: 1) Navigate to AxeOS using the device's IP address. 2) navigate to the bottom of the settings screen and select the latest releases button. 4) If your firmware is up to date, you're good to go! 5) If there has been a new release, select the esp-miner.bin link and download it to your computer or mobile device. 6) Locate the update firmware window on the bottom of the settings page and select browse to upload your new esp-miner.bin file into AxeOS 7) Once successfully updated, your Bitaxe will resume to normal operation and no further changes need to be made. 8) If the web dashboard fails or the OLED is blank, hold the boot button, press reset, and use the web flasher below to load the latest firmware via a USB-C data cable (be sure to select keep configuration to prevent from factory restting the device and deleting your Wi-Fi credentials).
To reset your device back to factory settings use the web flasher below. Things you'll need: power to the device and a USB-C cable for data transmission. Our step-by-step guide walks you through this process!
To factory reset your device use the web flasher below. Things you'll need: power to the device and a USB-C cable for data transmission. Our step-by-step guide walks you through this process!
To overclock a Bitaxe Gamma, this may require hardware or advanced cooling upgrades depending on your devices current setup: 1) Navigate to AxeOS. 2) In settings, slightly increase the frequency in small increments (e.g., 25–50 MHz) to test stability. 3) If the hashrate drops or errors increase, incrementally raise the core voltage (e.g., 25–50 mV). 4) Keep checking temperatures throughout this process. Detailed overclock guide will be on the bottom of this page!

Setup Cooling: Install Ice Tower or Argon THRML cooler, apply thermal paste, add 120mm fan for voltage regulators. Ensure ASIC temperature <70°C, regulators <65°C.
Access AxeOS: Connect to the device’s Wi-Fi (“Bitaxe_XXXX”) or IP on OLED. Open http://<bitaxe_ip>/#/settings?oc in Google Chrome.
Adjust Settings: Increase frequency by 25–50 MHz from default (525–596 MHz, 1150 mV). Test settings:
600 MHz, 1100 mV: ~1.4 TH/s, 19 J/TH.
725 MHz, 1200 mV: ~1.6–1.8 TH/s, 22 J/TH.
850 MHz, 1300 mV: ~2 TH/s, 25 J/TH (chip-dependent). Increase voltage by 25 mV if unstable. Save settings.
Monitor: Check hashrate, errors, and temperatures on AxeOS for 15–60 minutes. Reduce frequency if errors rise or miner reboots.
Verify: Mine to stable pool or node. Ensure input voltage >4.8V.
Risks: Overheating (>70°C) or high voltage (>1300 mV) damages chip. Overclocking may void warranty.
