A small Texas mining hardware company is releasing what it says is the most powerful open-source touchscreen bitcoin miner currently available to home users.
Houston-based Solo Satoshi announced the launch of the Bitaxe Turbo Touch, a compact device designed for hobbyists and home miners that delivers more than double the hashrate of other touchscreen miners in its category.
According to a note shared with Bitcoin Magazine, the unit produces about 2.15 terahashes per second (TH/s).
The product builds on the open-source Bitaxe GT 801 platform and is powered by dual BM1370 ASIC chips, the same chips used in the industrial-scale Bitmain Antminer S21 Pro. The chips allow the device to achieve efficiency of roughly 18 joules per terahash, according to the company. During testing, the device reportedly reached over 3 TH/s when overclocked.
The miner includes a 4.3-inch capacitive touchscreen that displays real-time network and mining data. Eight rotating displays show metrics such as hashrate performance, bitcoin price, current block height and recently mined blocks.
Network information is pulled from mempool.space, a widely used blockchain data explorer.
Matt Howard, founder and chief executive of Solo Satoshi, said the company prioritized transparency when building the device.
“We built this because we believe the tools people use to interact with Bitcoin should be fully verifiable,” Howard said in a statement. “Every line of code between the ASIC chips and the pixels on the touchscreen is open source.”

The miner runs two open-source firmware layers: AxeOS, which manages the mining operations, and BAP‑GT‑TOUCH, which powers the touchscreen interface. Both software repositories, along with hardware schematics and board layouts, are publicly available under an open hardware license.
The device consumes about 43 watts of power and produces roughly 35 decibels of noise, placing it closer to the sound level of a quiet room than traditional industrial mining rigs. At typical U.S. residential electricity rates, Solo Satoshi estimates the miner would cost about $3.70 per month to operate.
The Bitaxe Turbo Touch connects through a 2.4 GHz Wi-Fi module using an ESP32-S3 microcontroller, and configuration is handled through a browser-based dashboard. Each unit is assembled in the United States and tested for hashing performance before shipping, the company said.
Solo Satoshi is positioning the device against other compact touchscreen miners such as the Braiins BMM 101. The company says its model delivers significantly lower cost per terahash — about $151 per TH compared with roughly $299 per TH for the Braiins device.
The launch also highlights a growing niche within the bitcoin mining industry focused on open-source hardware. While most large mining operations rely on proprietary equipment from major manufacturers, smaller developers and hobbyist communities have pushed for transparent designs that can be modified and audited.
Solo Satoshi said it worked with the Open Source Miners United community to develop parts of the device, including an accessory communication protocol that allows developers to build additional displays and hardware integrations.
The company traces its involvement in touchscreen miners to late 2024, when it collaborated on the early concept of the Bitaxe Touch. When later versions of the device shipped with closed-source firmware, Solo Satoshi decided to create its own fully open-source alternative.
According to the company, open-source bitcoin miners have collectively produced more than $1 million in verifiable block rewards, including several widely publicized solo mining successes in recent years.
