Description
Overview
The BitSupra 1368 is a Bitaxe Supra wrapped inside D-Central’s custom 3D-printed Supra car shell — a fully assembled, ready-to-mine open-source Bitcoin solo miner that looks as good as it hashes. Under the hood sits a genuine BM1368 ASIC chip — the same silicon that powers the Antminer S21 — delivering 500-700 GH/s of SHA-256 hashrate from your desk.
This is not a toy or a novelty item. The BitSupra 1368 is a real ASIC miner running AxeOS firmware, connecting directly to a solo mining pool, and hashing against the Bitcoin network 24/7. The Supra-inspired enclosure is 3D-printed from PETG in Canada by D-Central’s team, with integrated ventilation channels that direct airflow over the ASIC and VRM. Every unit is assembled, tested, and burned in before shipping.
D-Central has been a pioneer in the Bitaxe ecosystem since the beginning — the first company to manufacture the Bitaxe Mesh Stand, and one of the earliest to develop heatsinks, cases, and complete builds around the Bitaxe platform. The BitSupra 1368 represents our approach to solo mining: take industrial-grade ASIC technology, hack it into something accessible, and package it so it belongs on your desk. Every hash counts.

Key Features
- Real ASIC Mining: The BM1368 is genuine Bitmain 5nm silicon — the same chip architecture in industrial miners costing thousands. This is not a microcontroller lottery ticket. It hashes SHA-256 at hundreds of gigahashes per second.
- Solo Mining Direct to Your Wallet: Connect to public solo mining pools like solo.ckpool.org or solo.d-central.tech. When you find a block, the entire block reward (3.125 BTC + fees) goes to your wallet. No pool fees, no custodial risk.
- AxeOS Web Interface: Configure everything from your browser — pool URL, Bitcoin address, clock speed, fan speed, voltage. Real-time monitoring of hashrate, temperature, accepted shares, and best difficulty.
- Custom Supra Enclosure: The 3D-printed PETG shell is not just cosmetic — integrated ventilation channels direct airflow across the ASIC and VRM, and the form factor keeps cables organized and the board protected.
- Overclockable: Push the BM1368 beyond stock frequencies through AxeOS. With proper cooling, many units exceed 700 GH/s. The enclosure is designed to handle the thermal load of overclocked operation.
- Fully Open-Source: Hardware design files, firmware source code, and schematics are all publicly available on GitHub. You own it completely — inspect, modify, fork, or build on top of it.

Frequently Asked Questions
Q: Can I power the BitSupra 1368 with USB-C?
No. The USB-C port on all Bitaxe Supra models is exclusively for firmware flashing and serial console access. Power must be supplied through the 5V DC barrel jack (5.5×2.1mm) using a 5V/6A power supply. Using USB-C for power will not work and could damage the device.
Q: What are my chances of finding a Bitcoin block?
At 600 GH/s, finding a block is a low-probability, high-reward event — true lottery mining. The statistical average time between blocks for a single Bitaxe at current network difficulty is measured in decades. But blocks have been found by solo Bitaxe miners — Block 853742 was mined by a Bitaxe. Every hash is a ticket, and every hash counts.
Q: Is the Supra case just cosmetic or does it help cooling?
Both. The PETG shell includes integrated ventilation channels that direct airflow from the 40mm fan across the ASIC chip and voltage regulator. It is not an airtight enclosure — it is a directed-airflow shroud that also protects the board from dust and physical contact.
Q: Can I remove the Bitaxe board from the Supra case?
Yes. The BitSupra 1368 is a standard Bitaxe Supra board mounted inside the Supra shell. You can remove it and use it bare, mount it in a different case, or use any standard Bitaxe accessory — heatsinks, stands, sockets — all work with the board inside.
Q: Do I need technical knowledge to set it up?
Minimal. Plug in the power supply, connect to the Bitaxe’s Wi-Fi access point from your phone or computer, open the AxeOS web interface, enter your pool URL and Bitcoin address, and start mining. The entire setup takes under 5 minutes. No command line, no coding, no special software.
Q: What is the difference between this and a regular Bitaxe Supra?
The BitSupra 1368 is a Bitaxe Supra assembled inside D-Central’s custom Supra car enclosure. The mining hardware, firmware, and performance are identical. The difference is the enclosure — the Supra shell provides a unique aesthetic, directed airflow, and board protection in a conversation-piece form factor.
Why D-Central
D-Central Technologies has been in the Bitaxe ecosystem since the beginning. We created the original Bitaxe Mesh Stand — the first company to manufacture one — and have developed heatsinks, cases, sockets, and complete builds around the Bitaxe platform ever since. Every BitSupra 1368 is assembled and tested by the same ASIC repair technicians who service thousands of industrial miners each year. When you buy from D-Central, you are buying from the team that knows this hardware inside and out — literally down to the solder joints.
