NerdHat - Ethernet Expansion Board
Add wired Ethernet to your compatible Nerd miner. NerdHat supports NerdAxe Gaia, NerdOctaxe, NerdQaxe++ and NerdQaxe+ with model-specific jumper settings and Ethernet-enabled firmware.
Pre-order · Ships in November. You are reserving a unit from the first production run.
Compatibility & firmware
NerdAxe Gaia, NerdOctaxe, NerdQaxe++ and NerdQaxe+. Select JP2/JP3 for your model and use NerdHat-compatible Ethernet firmware.
Check your miner revision before installation. Later NerdOctaxe Gamma revisions (rev3.4+) share Ethernet pins with individual ASIC temperature sensing; consult the firmware notes for the supported configuration.
THE NERDHAT
Bye bye Wi-Fi. Hello Ethernet.
NerdHat adds wired Ethernet to your compatible Nerd miner. Connect an Ethernet cable from the board to your router or network switch and give your miner a stable connection without relying on Wi-Fi signal strength.
Built around the WIZnet W5500 controller with a standard RJ45 port, the compact board fits into the Nerd hardware ecosystem. Select your miner with the JP2/JP3 jumpers and run matching Ethernet-enabled firmware.

Select. Connect. Configure.
1. Match the board configuration
Switch off and disconnect your miner before fitting NerdHat. Check your model and hardware revision, then set JP2 and JP3 according to the board markings and the supported firmware configuration.
2. Install the matching firmware
Use a NerdHat-compatible Ethernet build for your exact miner model. The correct pin mapping matters; generic W5500 firmware is not interchangeable across every Nerd board.
3. Connect your network
Connect an Ethernet cable between the RJ45 port and your router or network switch. Complete your mining pool and wallet settings through your miner’s web interface.
Before installation: check the firmware integration notes for your miner revision. Ethernet cable and miner are required for use.
