Device Guide – Starting Your Solo Mining Journey
Summary: A detailed, hands-on guide to the most popular solo mining devices available today. Real specs, real prices, real recommendations.
The Golden Age of Solo Mining Hardware
Five years ago, if you wanted to solo mine, your only option was to buy an expensive, noisy, power-hungry ASIC miner — and then point it at a solo mining pool. There were no small devices designed specifically for individual hobbyists.
Today, that has changed completely.
An entire ecosystem of open-source, low-power, quiet, and beautiful solo mining devices has emerged. They are built by enthusiasts, for enthusiasts. And they are more accessible than ever.
Device 1: Bitaxe – The Community Favorite
Overview
The Bitaxe is the most popular solo mining device in the world — and for good reason. It was designed by an independent developer known as “Skot” (and later expanded by the open-source community). The Bitaxe is fully open-source: schematics, PCB layout, firmware — everything is available on GitHub.
Key Specifications (Bitaxe Ultra variant)
| Spec | Value |
| Hashrate | 850 GH/s – 1.2 TH/s (depending on overclock) |
| Power consumption | 15W – 25W |
| Chip | BM1397 (same as Bitmain’s Antminer S17) |
| Cooling | Small, quiet fan (customizable) |
| Display | OLED (shows hashrate, temp, shares, uptime) |
| Connectivity | WiFi (ESP32-S3) |
| Price | $150 – $250 USD |
What’s in the box?
- Bitaxe circuit board with pre-soldered components
- Small heatsink and fan
- Acrylic or 3D-printed case (depending on seller)
- USB-C cable (usually)
- *Power adapter not always included — use any 5V/2A phone charger*
Why people love it
The Bitaxe hits the sweet spot between performance, price, and community support. If you have a problem, dozens of people in the Bitaxe Discord or Telegram group have probably solved it before. The firmware is actively developed, with new features (like solo pool support, custom pools, and power tuning) added regularly.
Real user quote: “I bought my Bitaxe as a fun experiment. Three months later, I bought two more. It’s just satisfying to watch them run.”
Device 2: NerdAxe / NMMiner – The Desktop Beauty
Overview
The NerdAxe (also known as NMMiner) takes a completely different approach. Instead of chasing maximum hashrate, it prioritizes low power, tiny size, and aesthetics. The result is a device that looks like a piece of modern art — and can run off a power bank.
Key Specifications
| Spec | Value |
| Hashrate | 850 GH/s – 1.2 TH/s (dependin50 KH/s – 200 KH/s (yes, kilohashes — much slower than Bitaxe) |
| Power consumption | 12W – 5W |
| Chip | ESP32 (not an ASIC — it’s a microcontroller) |
| Cooling | Passive (no fan at all — completely silent) |
| Display | 1.8″ or 2.4″ color LCD |
| Connectivity | WiFi |
| Price | $40 – $100 USD |
Why would anyone buy a slower device?
Because speed isn’t the point.
The NerdAxe is not trying to compete with ASIC miners. It’s not even trying to be “efficient.” Instead, it’s a philosophical statement: mining can be beautiful, quiet, and accessible to anyone.
Think of the NerdAxe as the Mechanical Keyboard of the mining world. It’s not about maximum performance — it’s about the experience.
Real user quote: “I have my NerdAxe sitting on my work desk. It shows the time, the current hashrate, and a little animated pickaxe swinging. My coworkers always ask what it is. It’s a conversation starter.”
Device 3: ESP32-Based DIY Miner – For the True Maker
Overview
If you own a soldering iron and enjoy the smell of flux, the DIY route might be for you. The ESP32 is a $5 microcontroller that can be turned into a functional — albeit very slow — solo miner with a few additional components.
What you’ll need
- ESP32 development board ($5 – $10)
- Small OLED or LCD screen ($5 – $15)
- Some buttons and resistors ($2)
- 3D-printed case (optional, but nice)
- USB power cable
What you’ll learn
- How to flash firmware over serial
- How to configure WiFi on an embedded device
- How to connect to a stratum server
- How to display data on a small screen
- Basic electronics soldering
Is it worth it?
That depends entirely on what you value. If you want the highest hashrate for your dollar, buy a Bitaxe. If you want a beautiful desktop ornament, buy a NerdAxe. But if you want to understand every single component of a mining device — and you enjoy the process of building — the DIY route is incredibly rewarding.
Real user quote: *”My DIY miner runs at 5 KH/s — basically useless for finding a block. But I built it myself. I wrote parts of the firmware. That feeling is worth more than any ASIC.”*

Where to Buy
Official / Semi-Official Sellers
- Bitaxe: Available from various community sellers (check the Bitaxe GitHub or Discord for trusted vendors). Avoid random eBay sellers without reviews.
- NerdAxe / NMMiner: Available on Tindie, Etsy, and from community members.
- DIY components: Amazon, AliExpress, DigiKey, Mouser — or your local electronics shop.
Pro tip: When buying a pre-assembled device, ask if the seller provides support. The best sellers are active in the community and will help you troubleshoot if something goes wrong.
What to Buy as a First-Time Solo Miner
If you have no prior experience with mining or embedded devices, start with the NerdAxe. It’s cheap, it’s foolproof, and it will give you the joy of seeing “Accepted” messages without any frustration.
If you have some technical curiosity and want a real chance (however small) of finding a block, go with the Bitaxe Ultra. It’s the gold standard for a reason.
If you’re a hardware hacker who enjoys challenges — build your own. You’ll learn more than any pre-built device can teach you.
