GekkoScience Compac F – Bitcoin USB Stick Miner with 200–350 GH/s
The GekkoScience Compac F is a compact Bitcoin USB stick miner for the SHA-256 (SHA256d) algorithm. It delivers a hashrate of 200 to 350 GH/s from a single powered USB port – making it one of the most popular USB miners for solo Bitcoin mining, Bitcoin lottery mining and educational use. It is silent, low-power (≈ 5–15 W) and requires no dedicated mains outlet or noisy server rack. Inside sits the proven BM1397 ASIC chip, the same chip family used in the Antminer S17 and S17 Pro.
Looking for an easy entry into Bitcoin ASIC mining, want to add a real mining endpoint to your Bitcoin full node, or fancy your chances at solo lottery mining a block? The Compac F is purpose-built for exactly that – controlled via CGMiner, with adjustable clock speed (400–800 MHz) and core voltage (550–800 mV) – no soldering skills required.
Key benefits at a glance
- 200–350 GH/s hashrate – overclockable via console parameters with proper cooling.
- Efficiency ≈ 0.037 W/GH – excellent ratio for a plug-and-play USB miner.
- BM1397 ASIC chip (same chip family as the Antminer S17 Pro).
- Adjustable core voltage 550–800 mV via integrated voltage regulator – no soldering needed.
- Clock speed 400–800 MHz, set via CGMiner command-line parameters.
- Large aluminium heatsink with low thermal resistance.
- Cross-platform: runs on Windows, Linux (x86 / ARM, including Raspberry Pi) and macOS.
- Available with or without fan adapter – pick the variant that fits your setup.
- Ships from Germany – fast EU delivery, English-language e-mail support and illustrated setup guides for Windows, Linux/Raspberry Pi and macOS.
Who is the Compac F for?
The Compac F is built for hobby miners, Bitcoiners, students and developers who want a quiet, low-power ASIC miner on their desk or in their home lab – anyone who wants to experience real Bitcoin mining, complement a Bitcoin node, or take a shot at solo lottery mining. For industrial-scale profitable mining a large unit like the Antminer S21 is the right answer; for learning, experimenting and lottery mining, the Compac F is the right tool.

Package contents
- 1× GekkoScience Compac F USB stick miner in PP plastic packaging with magnetic closure
- Optional: fan adapter (depending on the selected variant)
What else do I need?
- A host PC or Raspberry Pi running Windows, Linux or macOS
- A powered USB hub with a strong power supply (e.g. GekkoScience 7-port USB hub, Anker 9-port, Orico 10-port) – a single PC USB port typically does not supply enough
- A fan for active cooling – mandatory above 400 MHz clock.
- A Bitcoin mining pool account (e.g. a solo pool, public solo CKPool, or a standard pool such as Braiins, F2Pool or Ocean) and a Bitcoin wallet address for payouts.
Note: due to the 18 mm height of the heatsink, not all ports of a USB hub can necessarily be used at the same time – depending on the hub model.

Frequently Asked Questions (FAQ) about the GekkoScience Compac F
What is the GekkoScience Compac F?
The GekkoScience Compac F is a Bitcoin USB stick miner for the SHA-256 algorithm. It produces 200–350 GH/s from a single powered USB port and is built around the BM1397 ASIC chip. It is controlled via the CGMiner mining software and is ideal for solo Bitcoin mining, Bitcoin lottery mining and educational projects.
How many GH/s does the Compac F deliver?
The Compac F delivers 200 to 350 GH/s out of the box. With proper active cooling and adjusted clock (up to 800 MHz) and core voltage (550–800 mV), further overclocking is possible.
Can you earn Bitcoin with the Compac F?
In classic pool mining the earnings of a 200–350 GH/s device are small and, at European electricity prices, generally below the cost of power. The Compac F is therefore mainly used for solo (“lottery”) mining, for learning and for testing a Bitcoin mining setup. In solo mining the chance of finding a block is statistically very small, but a successful block pays out the full block reward.
How much power does it consume?
Power draw is between 5 W and ~15 W per USB port – depending on clock speed and core voltage. The efficiency averages around 0.037 W/GH.
What software do I need for the Compac F?
The Compac F is operated with a GekkoScience-specific modified version of the popular CGMiner mining software. It allows the clock rate to be set via console parameter. The core voltage is set via the integrated voltage regulator – no soldering required.
Does the Compac F work with a Raspberry Pi?
Yes. The Compac F runs on Linux x86 as well as Linux ARM, which makes it fully compatible with the Raspberry Pi. A powered USB hub with its own power supply is required, because the Pi itself cannot deliver enough current to the miner.
Do I need a powered USB hub?
Yes – a powered USB hub with a strong power supply is strongly recommended. Standard PC USB ports can be damaged by the up to 15 W draw of the miner. Suitable hubs include the GekkoScience 7-port USB hub, Anker 9-port and Orico 10-port.
Do I need a fan?
Yes – above 400 MHz, active fan cooling is mandatory to protect the ASIC chip from overheating. That is why a variant with fan adapter is available alongside the version without.
Which cryptocurrencies can I mine with the Compac F?
All coins based on the SHA-256 algorithm (SHA256d) – first and foremost Bitcoin (BTC), plus e.g. Bitcoin Cash (BCH) and other SHA-256 forks.
How is the Compac F different from the Compac A1?
The GekkoScience Compac A1 is the newer model and delivers 300–500 GH/s. The Compac F is the proven entry model at 200–350 GH/s and a lower price point – ideal for beginners, small home setups and educational use.
Where does the Compac F ship from?
bitshopper.de ships the Compac F from Erlangen, Germany. There are no additional customs charges within the EU; outside the EU, import duties and taxes may apply.
Is English-language support available?
Yes. bitshopper offers e-mail support in English (info@bitshopper.de) and provides illustrated step-by-step setup guides for Windows, Linux/Raspberry Pi and macOS.
