The Bitaxe Gamma 601 is a compact, open-source Bitcoin miner built around one BM1370 ASIC. It is best understood as a hands-on home mining platform rather than a miniature substitute for an industrial machine. The official Bitaxe hardware project describes the Gamma family as the fifth major Bitaxe revision and identifies the BM1370 as the chip used in the Antminer S21 Pro. That design choice gives the board a useful combination of modern efficiency, low absolute power draw, Wi-Fi operation and open documentation.
LeedMiner’s catalog records the Gamma 601 at about 1.2 TH/s, 18 W and 15 J/TH. The exact listing was published and site-visible but out of stock when checked on August 13, 2026, so this review does not present it as immediately orderable. Use the specifications as a reference, then verify the live listing, included power supply, firmware version and inventory before purchase.
What the official design confirms
The official bitaxeGamma repository states that the platform is designed to be easy to run over Wi-Fi without an external computer, low power, low noise and compatible with Stratum V1 pools. It also publishes the KiCad design files, schematic, bill of materials and manufacturing information. The project’s Gamma 601 release notes identify board 601 as the first Gamma release with the BM1370 ASIC and document a revised fan connector and routing changes.
Open source does not mean every assembled unit is identical. Sellers can use different heatsinks, fans, power adapters, cases and firmware builds. Review the exact bill of materials and the vendor’s assembly quality rather than assuming that the board revision alone defines the finished product.
Performance and electricity
At the catalog values, 18 W divided by 1.2 TH/s equals 15 J/TH. A continuously running 18 W device uses about 0.432 kWh per day, or about 12.96 kWh in a 30-day month. Multiply that energy by your all-in electricity tariff, not only the advertised generation rate. At $0.15/kWh, the illustrative monthly electricity cost is about $1.94 before router power, cooling or taxes.
Hashrate is not guaranteed at every temperature or voltage. The official project warns that the Gamma uses more power than earlier Bitaxe generations and can overheat more easily when frequency or voltage is raised, especially with a stock heatsink and fan. Start from the seller’s supported settings, watch ASIC temperature and fan behavior, and change one variable at a time. Aggressive tuning can trade stability and hardware life for a modest hashrate increase.
Firmware and open-source workflow
The companion official ESP-Miner repository provides the firmware used across supported Bitaxe hardware. Check its release notes and supported-board list before flashing. Export or record pool settings first, use the web flasher or update path documented for the installed build, and avoid interrupting power during a firmware write. After an update, confirm the reported board model, ASIC frequency, voltage, fan control and accepted shares. Open firmware makes inspection and improvement possible, but it also places more responsibility on the owner to distinguish official releases from unverified binaries.
Setup and pool choice
A preassembled unit normally needs a suitable 5 V power adapter, a stable 2.4 GHz Wi-Fi network, a Bitcoin payout address and compatible pool credentials. The official project notes a center-positive 5.5 × 2.1 mm barrel input and recommends adequate power-supply headroom; USB-C is used for programming rather than primary mining power. Confirm the adapter and connector supplied with the exact unit.
For predictable small payouts, use a pool that accepts low-hashrate workers and publishes its minimum payout, fees and regional Stratum endpoints. For solo or lottery mining, understand that 1.2 TH/s is tiny relative to the Bitcoin network: a valid block is possible, but the waiting time is highly uncertain. A solo result should be treated as an experiment, not forecast revenue. Compare payout modes in the Bitcoin mining pool guide and model electricity with the LeedMiner profit calculator.
Thermal and reliability checklist
- Place the miner on a stable, nonflammable surface with unobstructed intake and exhaust.
- Use the correctly rated power adapter and inspect the barrel connector for heat.
- Keep firmware current through the official Bitaxe/ESP-Miner project or the seller’s verified release channel.
- Record temperature, accepted hashrate, rejected shares, fan speed and restart behavior for at least 24 hours.
- Keep pool credentials and payout controls separate from general household accounts.
Do not evaluate noise from a catalog number alone. A small fan can sound sharper than a larger slow fan, and an enclosure may amplify vibration. Test the actual unit in the intended room before treating it as bedroom or desk equipment.
Alternatives for a small home setup
The Gamma 601 listing was out of stock at the time of this review. The following LeedMiner products were published, visible and in stock on August 13, 2026. They are not substitutes for the Gamma’s open-source board; they are practical comparison points for buyers who want a small SHA-256 device now.
Product card — Lucky Miner LV06 (500 GH/s) Listed at $74.00 with a catalog power draw of 13 W. Its lower hashrate and price suit a low-cost learning setup. View the Lucky Miner LV06
Product card — Lucky Miner LV07 (1 TH/s) Listed at $87.00 with a catalog power draw of 30 W. Compare its closed product design, power adapter and support terms with the Gamma’s open hardware. View the Lucky Miner LV07
Prices and availability can change. If a live product has no price, treat it as Inquiry and request a dated quotation rather than assuming a pending amount.
Who should buy the Gamma 601?
The Gamma 601 fits developers, Bitcoin educators and home miners who value open schematics, firmware experimentation and very low absolute power consumption. It is less suitable for buyers whose only goal is predictable fiat profit or who do not want to monitor temperature, firmware and Wi-Fi behavior. The most valuable output may be practical understanding: how shares, pools, cooling, tuning and open hardware interact.
Before ordering, confirm the board revision, real BM1370 hardware, seller reputation, assembly quality, cooling package, power adapter, firmware image, warranty and stock. Compare current small miners in the LeedMiner comparison tool, or contact LeedMiner for a dated availability check.
