Product Overview

The Nerdminer NerdQaxe++ is a high-performance open-source SHA-256 Bitcoin miner delivering approximately 4.8 TH/s from a dedicated ASIC chip array in a compact, low-noise form factor. Building on the BitAxe/Nerdaxe open-source mining project, the NerdQaxe++ uses multiple BM1366 ASIC chips (the same chip found in the Antminer S19 XP Pro series) to achieve its 4.8 TH/s hashrate — representing a significant step up from single-chip devices like the BitAxe Gamma 601 (1.2 TH/s) and Nerdnos (100 GH/s).

The “++” designation indicates this is an enhanced variant of the NerdQaxe design, with improved hardware implementation and efficiency compared to earlier NerdQaxe models. At 4.8 TH/s from approximately 80–100W, the NerdQaxe++ occupies a unique niche: it delivers more hashrate than most hobby Bitcoin mining devices while still operating at home-friendly power levels with manageable noise and a compact form factor suited to solo Bitcoin mining participation.

For South African Bitcoin enthusiasts, the NerdQaxe++ offers meaningful solo mining lottery hashrate at very low operating costs. At 80–100W, it runs comfortably on a standard household circuit, is manageable on a home inverter during load shedding, and contributes genuine SHA-256 proof-of-work to the Bitcoin network — while running open-source firmware that the global Bitcoin community actively develops and maintains.

Key Features

• ~4.8 TH/s SHA-256 ASIC Hashrate: High hobbyist-scale Bitcoin mining output from multiple BM1366 ASIC chips. At 4.8 TH/s, the NerdQaxe++ is among the highest-hashrate open-source home Bitcoin mining devices available.
• Multiple BM1366 ASIC Chips: Uses the same chip as the Bitmain Antminer S19 XP Pro series — genuine ASIC-level SHA-256 efficiency, not a microcontroller approximation. Multiple chips combined to reach 4.8 TH/s.
• 80–100W Power Consumption: Low power draw for a 4.8 TH/s ASIC miner. Manageable on standard home circuits without dedicated industrial electrical infrastructure.
• Open-Source AxeOS Firmware: Runs AxeOS open-source firmware with web-based pool configuration, hashrate monitoring, and remote management via home Wi-Fi network.
• Wi-Fi + Ethernet Connectivity: Connects to home network via Wi-Fi or Ethernet for pool connection and monitoring.
• Low Noise Operation: Significantly quieter than commercial ASIC miners at equivalent hashrates — suitable for home office or residential environments.
• Load-Shedding Manageable: At 80–100W, a standard home inverter and battery can sustain the NerdQaxe++ for many hours through South African load-shedding periods.

Power & Installation Notes

The NerdQaxe++ draws approximately 80–100W. In South Africa, a standard household circuit handles this comfortably. A dedicated 16A circuit is recommended for any sustained mining equipment, but the low wattage means there’s no industrial electrical planning required. South Africa’s 230V / 50Hz supply is fully compatible.

Load shedding resilience is very good at this power level. A 3 kVA home inverter with a 5 kWh battery can sustain the NerdQaxe++ for approximately 50 hours — covering all standard South African load-shedding stages with substantial reserve. Even a basic 2 kVA inverter with a 2.4 kWh battery provides approximately 24 hours of runtime.

Cooling is handled by the unit’s integrated system. Ensure good ventilation in the operating environment but no special thermal infrastructure is required.

Electricity Cost Context — South Africa

At R2.80/kWh reference tariff, the estimated monthly electricity cost is:

(90 ÷ 1,000) × 24 × 30 × 2.80 = R181.44 per month

This is an operating cost estimate only. At approximately R181/month, the NerdQaxe++ has one of the lowest operating costs per TH/s of any Bitcoin mining device available. Solo mining at 4.8 TH/s provides a meaningful (if still remote) lottery chance at the Bitcoin block reward while keeping electricity costs minimal.

Ideal Use Cases

• Solo Bitcoin mining with meaningful hashrate: At 4.8 TH/s, the NerdQaxe++ provides one of the best “solo mining lottery” experiences available from open-source hardware. Point at CK Solo Pool for the chance at the full block reward.
• Home Bitcoin mining with minimal infrastructure: Low power, manageable noise, and standard household electrical requirements make the NerdQaxe++ one of the most practical high-hashrate home mining options for South Africa.
• Load-shedding-resilient mining: At 80–100W, the NerdQaxe++ can run for 50+ hours on a standard home inverter — genuinely load-shedding-proof for practical purposes.
• Bitcoin community participation: The open-source hardware and AxeOS firmware support a community of developers and miners. Running a NerdQaxe++ means contributing to both Bitcoin’s proof-of-work security and the open-source mining hardware ecosystem.

Frequently Asked Questions

Does the NerdQaxe++ work on South African power?
Yes. Standard household circuits handle it comfortably. Confirm exact power input (USB-C or barrel jack) at time of purchase — all standard adapters are compatible with South Africa’s 230V supply.

How does the NerdQaxe++ compare to the BitAxe Gamma 601?
The NerdQaxe++ delivers 4.8 TH/s vs the BitAxe Gamma’s 1.2 TH/s — 4× more hashrate from multiple chips vs a single BM1370 chip. The NerdQaxe++ uses multiple BM1366 chips vs the Gamma’s single BM1370. For solo mining lottery purposes, the NerdQaxe++ provides a more meaningful hashrate contribution.

Can it run during load shedding?
Yes — for 50+ hours on a standard home inverter with a 5 kWh battery. One of the best load-shedding profiles of any real ASIC mining device.

What pool should I use?
For solo mining, public-solo.ckpool.org is the most widely used public Bitcoin solo pool. For pool mining, any SHA-256 pool supporting Stratum V1 is compatible. Configure via the AxeOS web interface on your home network.

Is the NerdQaxe++ truly open-source?
Yes — the hardware schematics, PCB design, and AxeOS firmware are all open-source. The community actively develops both the hardware and firmware. You can flash custom firmware, modify the design, or contribute to the project.
