Product information
Nerdaxe Gaia: 2.6 TH/s from a single BM1373
The Nerdaxe Gaia is the generation change in the Nerdaxe format. The board carries a single BM1373 ASIC with around 2.6 TH/s at roughly 25 W, so about 10 J/TH – around a third less energy per terahash than the BM1370 generation at roughly 15 J/TH. Everything around it stays familiar: ESP32-S3, AxeOS, 2.4 GHz Wi-Fi, USB-C and the 1.9-inch TFT showing the operating values. The Gaia is a pre-order; the first batch is sold out and the second batch ships from 7 November 2026.
Two things shape everyday use. A 40 mm PWM fan keeps the ASIC in check, and you define its curve in AxeOS. And power draw stays manageable: roughly 25 W add up to about 18 kWh a month – twice the hash rate of a Nerdaxe Gamma for barely more power.
That is exactly the point of solo mining: every hash is a ticket in the same draw the large farms take part in. If your Gaia finds the matching block, the full reward of currently 3.125 BTC plus transaction fees lands on your own address, undivided and with no provider in between. Along the way, your device checks transactions and strengthens the network. How small the chance is, is explained in our solo mining guide.
Why the Gaia is ahead of the previous generation
- Twice the hash rate in the same format: around 2.6 instead of 1.3 TH/s, without a second chip, without a larger power setup and without a rack in the basement.
- Roughly 10 J/TH: power draw only rises from about 15 to 25 W while compute doubles.
- One chip instead of many: fewer components, fewer points of failure and a device that can run around the clock.
- Just as open: AxeOS with your own pool, your own address and free choice of frequency and voltage. No account, no cloud service, no vendor lock-in.
Why a single ASIC is the better answer here
There are two ways to more hash rate: more chips or a better chip. The Gaia takes the second route. That keeps the device small and lets a single 40 mm fan do the job. The price of that design is the ceiling: with the stock cooler, around 2.6 TH/s is the end of the line. The Nerdaxe Gaia Copper Pro with its larger AXP60 cooler gets more out of the same chip; beyond that, the next device class begins.
For home mining that is the better arithmetic: one device, one power supply, one socket and one number on the display.
Pre-order: what that means for you
The Gaia is a new generation and sold as a pre-order: the first batch is sold out, the second batch ships from 7 November 2026. Orders placed now are part of the second batch, strictly in order of purchase. If you want to start right away, the Nerdaxe Gamma is the alternative in the identical form factor: same display, same operation, half the hash rate.
Up and running in minutes
The new ASIC changes nothing about the procedure: a socket, 2.4 GHz Wi-Fi and a browser are enough. The steps in detail are in the Nerdaxe setup guide.
- 1
Connect it
Plug in the power supply and start the miner. On first boot the Gaia opens its own Wi-Fi network for configuration.
- 2
Set up Wi-Fi
Switch to that network, select your 2.4 GHz home network and enter the password. The miner then sits on your network and is reachable through the router.
- 3
Store pool and address
Open AxeOS in a browser, enter pool, worker and your Bitcoin address, save and restart. From that moment every hash counts.
Who the Nerdaxe Gaia is for
For everyone already running an open-source miner who wants more hash rate without changing device class. The Gaia stays a desktop device with one chip, one fan and one power supply. It also works as a second unit next to a Bitaxe, because firmware and operation are identical.
It is less of a fit in two cases. First, if you want to mine immediately – the first batch is sold out and the second batch ships from 7 November 2026. Second, if you are after maximum hash rate: the NerdQaxe++ reaches around 4.8 TH/s but draws roughly 80 W, about three times as much.
What you need to run it
Power supply, mount and quick start guide are included; beyond that you only need a socket, your 2.4 GHz Wi-Fi and a Bitcoin address. No PC required, because AxeOS runs on the device.
For the location the same rules apply as for any air-cooled miner: stand it free, do not blow the exhaust against a wall, and keep an eye on the temperature during the first few days. 25 W of waste heat is little, but it still has to go somewhere.
Accessories and sensible upgrades
A Gaia on its own is a complete setup. It gets interesting when you make it quieter or put it behind your own infrastructure.
- Cooling for quieter fans and more surface area if you want to raise the clock.
- LiquidBox V5 if your own Bitcoin node should stand next to the miner.
- Power supplies, mounts and small parts for continuous operation.
Ready for your Nerdaxe Gaia setup?
2.6 TH/s, roughly 25 W, about 10 J/TH and a single BM1373: the Gaia is the upgrade for everyone who wants to stay in the open format and still put more hash rate on the desk. Pre-ordering means being part of the first batch.

Super schnelle Lieferung! Obwohl der Versand erst mit zweiter Charge ab November angekündigt war, kam das Gerät schon im Oktober. Ware war gut verpackt und funktioniert einwandfrei.
It's AWESOME. (I just wish I bought it with a noctua fan, in fact it should be default fan, the standard one is noisy)
I like it
Great little miner! Easy to set up, runs stable and the display is a nice touch. Very happy with it
Ich habe noch wenig Ahnung von der Materie aber ich denke er macht was er soll. Einrichtung Dank sehr ausführlichen Anleitung ein Kinderspiel.
Ein einziger BM1373 auf dem Board und trotzdem standen nach dem ersten Einschalten schon 2.4 TH/s auf dem Display bei rund 28 W aus der Steckdose. So habe ich ihn Samstag und Sonntag einfach laufen lassen. Am Montag kam dann über den Flasher von bitaxe.de OSM-OS drauf und dank der Option Konfiguration behalten waren WLAN Pool und Adresse danach noch da. Am Dienstag hat mich die Neugier gepackt und mit 400 MHz und 960 mV zeigt er jetzt 2.75 TH/s bei knapp 34 W. Damit liegt er sogar über den 2.6 aus dem Produkttitel und der Chip bleibt mit der PID-Regelung bei 60 Grad. Höher gehe ich nicht weil bei 440 MHz laut einem Issue auf GitHub der Spannungsregler abschaltet. Das eigentliche Highlight ist für mich aber das Display. Mit den zwei Tasten wechselt man die Seiten und ich lande abends fast immer auf der Netzwerkseite mit der aktuellen Difficulty und vergleiche sie mit meiner Best Difficulty. Der Abstand ist lächerlich groß und macht trotzdem jeden Abend Spaß. Mal sehen wie weit mein Rekord bis Weihnachten klettert.
Efficiency was the whole reason I bought this, so naturally each of my two miners now sits on its own smart plug. The Bitaxe Gamma pulls about 18 W for 1.2 TH/s, roughly 15 J/TH. The Gaia shows 2.4 TH/s on its screen while the plug reads 27 W, which works out to a little over 11. Double the hashrate for nine extra watts, from something that takes up about the same space on the desk, and that trade suits me far better than an 80 W box with a fan to match. Everything is still at stock, fan on auto, chip hovering just under 60 degrees. What I did not see coming is how much I enjoy the bigger screen after a year of squinting at the Gamma's tiny OLED. I now keep a little spreadsheet of watts per terahash for both machines, updated every Sunday, which my flatmate finds deeply worrying. It arrived a fortnight ago, and the bit of warm air it pushes across the desk is already welcome now that the evenings are getting cold.
Top - War wirklich schnell einzurichten und läuft nun. Ich drücke mir die Daumen. :-)
Pre-ordering something I had never seen in real life made me a little nervous. I pictured months of waiting and a parcel turning up sometime next spring. In the end the first batch went out only days after I ordered in mid-September, and mine arrived ten days ago. As a complete newcomer I had watched three setup videos beforehand and barely needed them, because the whole thing was done before the second video would have ended. What I love is that nothing is hidden. The screen shows the hashrate, about 2.4 TH/s, the chip temperature and the power draw, which hovers around 27 watts. I pointed it at a solo pool, fully aware that the chance of ever hitting a block is tiny, and I still catch myself opening the dashboard several times an evening to see what it has been up to. Getting a unit from the first batch before it sold out feels like a small win, and I have learned more about how Bitcoin actually works in these ten days than in years of just reading about it.
Super Teile die kleinen Dinger! 😎
Gerät aus der ersten Charge, läuft seit gut einer Woche durch. Mit den Standardwerten stehen rund 2,4 TH/s bei 26 W in der Weboberfläche, also knapp 11 J/TH, mein NerdQaxe++ braucht für 4,8 TH/s etwa 80 W und liegt damit bei knapp 17 J/TH. Die letzten warmen Septembertage mit 25 Grad im Arbeitszimmer hat er mit 60 bis 61 Grad am Chip weggesteckt, der Lüfter regelt das aus. Schön, das der Effizienzsprung der neuen Chipgeneration auch in so einem kleinen Gerät ankommt.
Got mine from the first batch a week ago, what a chip: 2.45 TH/s at 28 W, thats 11.5 J/TH. My Bitaxe GT at 43 W suddenly looks thirsty.
Weil es bei aller Vorfreude gern untergeht, hier der unspektakuläre Teil: Der Gaia läuft mit einem 12-V-Netzteil, der Nerdaxe Gamma mit 5 V, und beide Netzteile haben denselben 5,5-x-2,1-mm-Hohlstecker. Die verwechselt man im Halbdunkel schneller, als einem lieb ist, und 12 V haben an einem 5-V-Miner nichts verloren. Bei mir steht ein Gamma auf dem Schreibtisch und der Gaia soll daneben, also bekommt das 12-V-Netzteil beim Auspacken sofort einen dicken Streifen rotes Isolierband und eine eigene Steckdosenleiste. Zum Gerät selbst kann ich noch nichts sagen. Vorbestellt ist er seit zwei Tagen, eine Versandmail gibt es noch nicht, und ich gebe zu, dass ich häufiger ins Postfach schaue, als mir lieb ist. Gekauft habe ich ihn wegen des BM1373: ein einzelner Chip, dieselbe Bauform wie mein Gamma und nach allem, was man liest, gut die doppelte Hashrate bei deutlich weniger als doppeltem Verbrauch. Mit den 2,6 TH/s aus dem Titel rechne ich trotzdem nicht, knapp 2,5 würden mir reichen.
