Home Bitcoin mining has had a remarkable renaissance — and right at the center of it sits the NerdQaxe++. Born from the open-source Bitaxe movement and powered by the same cutting-edge BM1370 ASIC chips found inside Bitmain’s industrial Antminer S21 Pro, the NerdQaxe++ is turning heads across the crypto mining community. Whether you’re a seasoned miner looking to add a low-power satellite to your fleet, or a curious Bitcoin enthusiast who wants to participate directly in the network from your living room, this device is worth your full attention.
We’ve done a deep dive on specs, real-world performance, setup, and profitability — so here is everything you need to know before you buy.
What Is the NerdQaxe++?
The NerdQaxe++ is a compact, open-source, solo Bitcoin miner developed by NerdMiner — part of the broader open-source mining hardware ecosystem that includes the original Bitaxe project. The “++” designation is meaningful: it signifies that this device uses the newer, more powerful Bitmain BM1370 ASIC chips (the same chips inside the Antminer S21 Pro, S21+, and S21+ Hydro), rather than the older BM1368 chips found in the original NerdQaxe+. Four of these chips are mounted on a single compact board, delivering a total hashrate of 4.8 TH/s while consuming only around 72–80 watts of power.
To put that in perspective: the NerdQaxe++ delivers the same hash power as the original Antminer S7, which required 135 chips when it launched in 2015 — but with only four chips. That’s how far ASIC chip technology has come, and it’s exactly what makes this device so compelling for home miners.

The Heart of the Machine: BM1370 ASIC Chips
The single biggest reason the NerdQaxe++ stands out from the crowded field of home miners is its chip choice. The NerdQaxe++ is powered by four Bitmain BM1370 ASIC chips — the same chips found in the Antminer S21 Pro, some of the most efficient industrial Bitcoin miners ever produced.
By using four of these elite chips on one compact board, the NerdQaxe++ achieves an efficiency rating that was unthinkable in desktop-scale mining hardware just two or three years ago. At stock settings, you get roughly 14.66 to 15 J/TH — comparable to what industrial farm operators pay premium prices to achieve. For a home device that sits on your desk and draws less power than a gaming laptop, those are extraordinary numbers.
Design & Build Quality
The NerdQaxe++ is a compact, no-frills device that’s clearly built for function over flash — but it doesn’t feel cheap. The unit is small enough to fit in the palm of your hand and comes with a sturdy metal stand that props it upright for optimal airflow and desk display.
The standout design feature is the onboard 1.9-inch LilyGO LCD color screen, which tracks live hashrate, Bitcoin price, ASIC temperature, and key network statistics — so you always know how your miner and the market are performing at a glance. Two programmable buttons on the display let you cycle through metrics without needing to open a browser.
Cooling is handled by the included Thermalright AXP90 X36 low-profile cooler — a name you’d typically see on CPU cooling setups rather than mining hardware. It’s a premium choice that keeps chip temperatures well within safe ranges and contributes directly to the device’s impressively low noise output.
At just 40dB of operating noise, the NerdQaxe++ is genuinely quiet. For reference, 40dB is roughly equivalent to the ambient noise of a library or a quiet conversation. This isn’t marketing language — it’s one of the most frequently praised features in real customer reviews.
Software & Setup: AxeOS Makes It Easy
One of the most compelling aspects of the NerdQaxe++ is how easy it is to get up and running. The device runs on AxeOS, a fully open-source, browser-based operating system. There is no software to install. Once connected to your Wi-Fi network, you simply type the device’s IP address into your browser to access the full dashboard, configure pools, adjust overclocking settings, monitor temperatures, and update firmware.
Setup from unboxing to mining takes approximately 30 minutes — even for first-timers. The process involves connecting to your WiFi, entering your mining pool details (or solo pool address) and Bitcoin wallet address, and hitting go. No command line. No technical background required.
The AxeOS dashboard shows you everything in real time: hashrate, share count, ASIC temperature, power draw, efficiency metrics, and more. Firmware updates are handled through the same browser interface. AxeOS receives regular updates with performance improvements, bug fixes, and new features — keeping your NerdQaxe++ current for optimal performance over time.
Real-World Performance: Does It Actually Deliver?
The advertised 4.8 TH/s is very real — but it takes a little patience out of the box. The NerdQaxe++ goes through a break-in period where the hashrate moves between 4.5–4.7 TH/s initially. Performance typically settles at 4.8 TH/s by day three and can reach peaks close to 5.0 TH/s when conditions are ideal.
Long-term stability testing is encouraging: the device holds steady with changes rarely exceeding 2% of rated performance. The firmware intelligently adjusts frequency settings as the system reaches thermal balance, which is a smart touch that protects both chip lifespan and efficiency.
Overclocking: If you want to push things further, the NerdQaxe++ can be overclocked — and the results are impressive. The device can be safely overclocked from its stock 4.8 TH/s to approximately 6.2–6.5 TH/s, though this increases power consumption from 72W to about 110–115W and may void the warranty. For those comfortable with the tradeoff, the overclocked performance is remarkable for a home device.
Solo Mining vs. Pool Mining: Which Should You Choose?
The NerdQaxe++ supports both solo and pool mining, and choosing between them is one of the most important decisions you’ll make as a home miner.
Solo Mining (the “Bitcoin Lottery”) is what most NerdQaxe++ owners pursue. You point the device at a solo pool like solo.ckpool.org, and every hash you compute is a direct attempt to find the next Bitcoin block and claim the full block reward — currently 3.125 BTC. The odds are long. With 4.8 TH/s against the entire Bitcoin network’s hash rate (measured in exahashes), you’re playing the lottery. But the lottery is real — Block #920,440 on the Bitcoin blockchain is proof that a solo miner with open-source hardware on a desk can find a full block and claim 3.15 BTC. One lucky solo miner’s NerdQaxe++ did exactly that.
Pool Mining gives you small, consistent daily payouts by combining your hashrate with thousands of other miners. At 4.8 TH/s, your daily earnings in a pool will be modest — the NerdQaxe++ is estimated to mine approximately $0.16 worth of Bitcoin per day, with electricity costs of around $0.12 per day at a $0.20/kWh rate. The margin is thin, but positive — and electricity rates vary significantly by location.
For most home miners, the real appeal of the NerdQaxe++ isn’t grinding out fractions of a cent per hour — it’s the experience, the education, the direct connection to the Bitcoin protocol, and yes, the very real shot at a life-changing block reward.
Electricity Cost & Profitability Breakdown
| Metric | Estimate |
|---|---|
| Daily Electricity Cost (@ $0.10/kWh) | ~$0.06/day |
| Daily Electricity Cost (@ $0.20/kWh) | ~$0.12/day |
| Monthly Electricity Cost (@ $0.20/kWh) | ~$11.50/month |
| Estimated Daily Pool Mining Earnings | ~$0.16/day |
| Solo Block Reward (if found) | 3.125 BTC (~$300,000+) |
| Approximate Break-Even (pool mining) | ~24–30 months |
Note: Profitability estimates are based on current Bitcoin prices and network difficulty and will fluctuate. Always calculate based on your specific electricity rate and current BTC price before purchasing.
What Coins Can the NerdQaxe++ Mine?
Because the NerdQaxe++ uses the SHA-256 algorithm, it can mine any SHA-256 compatible cryptocurrency — not just Bitcoin. Supported coins include Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin SV (BSV), eCash (XEC), Namecoin (NMC), Peercoin (PPC), Fractal Bitcoin (FB), and several others. That said, the overwhelming majority of NerdQaxe++ owners mine Bitcoin exclusively — both because it’s the highest-value SHA-256 coin and because solo BTC mining is the primary use case this device was designed for.

How Does the NerdQaxe++ Compare to Other Home Miners?
| Device | Hashrate | Power | Efficiency | Noise | Chips |
|---|---|---|---|---|---|
| NerdQaxe++ | 4.8 TH/s | ~75W | 15 J/TH | 40dB | 4x BM1370 |
| Bitaxe Gamma 601 | 1.2 TH/s | ~18W | 15 J/TH | ~35dB | 1x BM1370 |
| Heltec Bitaxe Gamma | 1.2 TH/s | ~20W | ~17 J/TH | ~35dB | 1x BM1370 |
| Antminer S19j Pro | 104 TH/s | 3068W | 29.5 J/TH | 75dB+ | 126 chips |
| NerdQaxe+ (older) | ~2.5 TH/s | ~60W | ~24 J/TH | 40dB | 4x BM1368 |
The NerdQaxe++ hits a genuinely compelling sweet spot: four times the hashrate of a single-chip Bitaxe Gamma at roughly four times the power — meaning the efficiency is nearly identical, but the absolute hashrate (and therefore your odds in the solo mining lottery) are dramatically higher. And compared to industrial miners like the Antminer S19, there’s simply no comparison on noise and power consumption for home use.
Setting Up the NerdQaxe++: Step-by-Step Overview
Getting your NerdQaxe++ up and mining is straightforward. Here’s what the process looks like:
Step 1 — Unbox and Inspect. Your package includes the miner unit, a 12V power supply, metal stand, and all necessary cables. Assemble the stand, seat the miner, and connect the power supply.
Step 2 — Power On. Plug in and power on the device. The LCD screen will light up and begin displaying startup information.
Step 3 — Connect to WiFi. Use your phone or laptop to connect to the NerdQaxe++’s initial hotspot. Enter your home WiFi credentials through the setup page that appears.
Step 4 — Access AxeOS Dashboard. Once connected to your WiFi, find the device’s local IP address and type it into your browser. The AxeOS dashboard loads instantly — no account needed, no app to install.
Step 5 — Configure Your Pool. Enter your mining pool URL and port (for solo mining, use solo.ckpool.org:3333), then enter your Bitcoin wallet address. Click save.
Step 6 — Start Hashing. That’s it. Your NerdQaxe++ is now mining Bitcoin. Watch the hashrate climb on the LCD and the share count tick up in the AxeOS dashboard. Every hash is a real attempt at the next block.
