Description
The Bitaxe Gamma 602 is the current revision of the open-source, single-chip Bitaxe Gamma Bitcoin miner. It uses one Bitmain BM1370 ASIC from the Antminer S21 Pro generation and produces approximately 1.2 TH/s at 18 to 20W, depending on the unit, firmware, and settings.
Each miner is assembled and tested in the USA with a Dark Horse pin-fin heatsink, 40 mm fan, removable OLED display, 2.4 GHz Wi-Fi, and AxeOS. Select a compatible 5V power supply and upright or stackable stand when configuring the product.

Bitaxe Gamma 601 vs. Gamma 602
| Feature | Gamma 601 | Gamma 602 |
|---|---|---|
| Mining platform | 1x BM1370 | 1x BM1370 |
| Nominal performance | Approximately 1.2 TH/s | Approximately 1.2 TH/s |
| Power routing | Original 601 layout | Wider VDD routing, additional input vias, and cleaned copper zones |
| Power-stage parts | Original 601 inductor and capacitor selection | Revised 300 nH inductor and higher-capacitance input and bulk capacitors |
| Heatsink mounting | Original 601 mounting layout | Revised plated M3 mounting-hole pattern |
| ASIC footprint | Original BM1370 footprint | BM1370 footprint corrections in the official hardware files |
| Manufacturing files | 601 production package | Updated PCB routing, DRC cleanup, BOM, placement files, and Gerbers |
The official Gamma 602 release describes design-for-manufacturing and routing improvements. The tagged hardware diff also shows the power-routing, component, mounting-hole, and footprint changes listed above. It does not claim a higher stock hashrate than Gamma 601. Both revisions use the same core BM1370 mining platform and Gamma firmware family.
When recovering firmware, always select the board revision printed on the PCB. This listing currently ships the Gamma 602. Review the official Gamma 601 to 602 hardware comparison on GitHub.
Bitaxe Gamma Performance Benchmarks
Solo Satoshi tested the following settings at approximately 69°F, or 21°C, with the Dark Horse heatsink and automatic fan control. Individual results vary.
| Frequency | Voltage | Temperature | Hashrate | Power |
|---|---|---|---|---|
| 525 MHz | 1150 mV | 49°C | 1.07 TH/s | 17.8W |
| 600 MHz | 1150 mV | 51°C | 1.22 TH/s | 20.1W |
| 700 MHz | 1250 mV | 59°C | 1.43 TH/s | 28.4W |
| 800 MHz | 1250 mV | 62°C | 1.63 TH/s | 32.2W |
| 850 MHz | 1250 mV | 62°C | 1.73 TH/s | 33.0W |
Higher settings require additional power and may require voltage-regulator cooling. Overclocking results are not guaranteed and can affect component life or warranty coverage. Review the complete Bitaxe Gamma overclocking guide before changing voltage or frequency.
Bitaxe Gamma Electricity Cost
An 18W miner running continuously uses approximately 12.96 kWh per 30-day month and 157.68 kWh per year.
| Electricity Rate | Monthly Cost | Annual Cost |
|---|---|---|
| $0.10/kWh | $1.30 | $15.77 |
| $0.12/kWh | $1.56 | $18.92 |
| $0.16/kWh | $2.07 | $25.23 |
| $0.20/kWh | $2.59 | $31.54 |
These figures cover electricity only. Mining revenue changes with network difficulty, Bitcoin price, pool terms, fees, uptime, and achieved hashrate. Use current values in the mining calculator.
