Set up the Nerdaxe Gamma
With this guide the setup takes a few minutes. Connect your device to Wi-Fi, enter your wallet address and check the performance – simple, clear and with FAQs for beginners.
Step by step
This guide takes you through the setup from unpacking to a running hash rate. The instructions are simple, free of jargon and ideal for newcomers.
The device at a glance
The Nerdaxe Gamma is a compact solo miner for the home. You connect it to your 2.4 GHz Wi-Fi, enter the pool details and use your Bitcoin address as the stratum user. After that the dashboard shows you whether everything is running.
Performance & temperature
From the factory the Nerdaxe Gamma runs at 525 MHz / 1150 mV and delivers around 1.3 TH/s at about 15 W. On individual units the temperature is higher at first; from 65 °C upwards check placement and airflow (see section 5 and section 8).
If you bought your Nerdaxe from us: thank you for your trust!
Have ready for the setup:
- Nerdaxe Gamma
- the credentials for your 2.4 GHz Wi-Fi
- your on-chain Bitcoin address (starts with bc1q, not a Lightning address)
- the power supply (PSU, 5 V DC / 6 A / 30 W, round DC plug)
Preparation
for absolute beginners
In this section you get your Nerdaxe ready to start:
You unpack the device, check the supplied parts, choose a suitable spot and connect the power supply. No prior knowledge needed – we walk you through it step by step.
STEP 1
OPEN THE BOX CALMLY
Take all parts out and remove the protective films.
STEP 2
CHECK THE CONTENTS
You will find the Nerdaxe Gamma, the mount or case, the power supply (PSU) and an info flyer. If something is missing or damaged, do not switch the device on and contact support or the shop you bought it from.
STEP 3
LOOK THE DEVICE OVER
Check the board, heatsink, cables and fan. Nothing should be loose. The fan should spin freely without rubbing. Look at the round DC (barrel) connector and check that it is firm.
STEP 4
FIND A SUITABLE SPOT
Place the miner on a firm, level surface with some distance to walls. A socket and Wi-Fi should be nearby. Avoid moisture and heat sources.
STEP 5
USE THE RIGHT POWER SUPPLY
The Nerdaxe Gamma needs 5 V DC through the barrel plug. USB-C is not intended for power here.
STEP 6
PREPARE THE CABLE
Do not plug the PSU into the socket yet. Untangle the cable so that it is not under tension.
STEP 7
PLUG THE POWER CONNECTOR INTO THE DEVICE
Insert the round plug straight into Power In. Do not use force and do not kink the cable.
STEP 8
SWITCH THE MINER ON
Plug the PSU into the socket. Display and fan usually start after one or two seconds.
STEP 9
READ THE WI-FI NAME (SSID)
The display shows NERDAXE_XXXX. Note that name if you need to.
STEP 10
CONTINUE TO THE WI-FI SETUP
Continue with the section connect Wi-Fi below.
Quick start in 3 steps
For the experienced: connect Wi-Fi, set the pool, check briefly – done.
1. Connect Wi-Fi: join NERDAXE_XXXX and set up your home Wi-Fi (see section 3).
2. Enter pool & wallet: open Pool Settings in the dashboard and enter host, port and your stratum user (your Bitcoin address). Click Save and then Restart.
3. Check in AxeOS: the dashboard shows hash rate, accepted shares and temperature.
Connect Wi-Fi
In short: you connect the Nerdaxe to your Wi-Fi and, if needed, open the setup page in a browser.
Step 1: if you have already done the preparation, the Nerdaxe Gamma is already running.
If you are starting here, plug the power supply into the socket. After one or two seconds the display and fan come on. On your phone or laptop a new Wi-Fi network called NERDAXE_XXXX appears. Select it.
Step 2: the setup page usually opens automatically. Wait a moment and stay connected to NERDAXE_XXXX.
Step 3: if no page opens, start your browser and enter http://192.168.4.1.
Step 4: go to Settings and enter any hostname, your Wi-Fi SSID and your password exactly. If unsure, tap the eye icon to show and check the password.
Step 5: store the details with “Save”.
Step 6: click “Restart” so your Nerdaxe reboots.
Step 7: the miner joins your home Wi-Fi and already starts mining. The display shows an IP address (for example 192.168.20.234). Note it down – you will use it to open the AxeOS dashboard.
Enter pool & wallet
In short: you open Pool Settings, enter host, port and your Bitcoin address as the stratum user, save and restart.
Step 1: open a browser and enter the IP address shown on the display (example: 192.168.20.234).
Step 2: switch to Pool Settings.
Step 3: enter the stratum host of your pool: pool.opensourceminers.de.
Step 4: enter port 3333.
Step 5: enter your stratum user. That is your Bitcoin address (on-chain). Replace the default address completely with your own. Do not add spaces.
Step 6 (optional): append a .worker to your address, for example .miner1. That makes several devices easier to tell apart in the pool.
Step 7: in the password field enter whatever your pool requires. If no password is needed, use x.
Step 8: store your settings with “Save”.
Step 9: click “Restart”. The miner reboots and connects to the pool.
Start & monitor mining
In short: here you see whether your Nerdaxe Gamma is working properly. The dashboard shows the hash rate, the counted accepted shares and the temperature. Take a moment to check. If something stands out, the notes below help.
Step 1: open the dashboard at the IP address if it is not open already (for example http://192.168.20.122).
Step 2: check the shares. Accepted should be rising. Rejected should stay as close to zero as possible.
Step 3: check the temperature.
Step 4: if no values appear, check host, port and BTC address on the pool tab. Improve the Wi-Fi signal if needed.
Step 5: once values appear, check the stability briefly: accepted should keep rising, rejected should stay close to 0 %. Keep an eye on the temperature and pick a cooler spot or more airflow if it runs high.
Step 6: your Nerdaxe Gamma is now running and mining – the setup is complete!
Done – your Nerdaxe is running!
Your miner is ready to go. The sections below are optional and help with tuning or solving problems after the setup.
Update the firmware
In short: update the firmware to keep your device stable and current.
If something goes wrong
- The web flasher does not detect a device – use Chrome or Edge, check the USB data cable and try another port.
- The page is unreachable after the update – wait one or two minutes and open the IP again.
- The update aborts – check the file and version and try again (a clean flash if necessary).
Method A – web flasher (recommended and easiest)
• Connect the Nerdaxe via USB-C directly to your computer – a data cable, not a USB hub. The device can keep running.
• Open flasher.bitaxe.de in Chrome, Edge or Opera on desktop.
• Click your device tile. “AxeOS original” is preselected; switch at the top if you want the optimized OSM-OS builds.
• Leave “Keep configuration” ticked – then Wi-Fi, pool and Bitcoin address survive the update.
• Click “Install firmware” and pick your miner’s serial port in the browser dialog (USB JTAG/serial, CP210x or CH340, depending on the board).
• Wait until the bar reaches 100 %. The miner reboots and is back on the network after about 30 seconds.
Firefox and Safari cannot flash over serial. There you download the update files and apply them in AxeOS under System.
Method B – online update (in the dashboard)
• Switch to Settings and click Check to look for newer firmware.
• If a new version is offered, download the two linked files: esp-miner.bin (firmware) and www.bin (web interface).
• Update the web interface first (Update Website → +Browse → www.bin), then the firmware (Update Firmware → +Browse → esp-miner.bin). Wait about 60 seconds; the device reboots automatically.
The order matters: www.bin first, then esp-miner.bin.
