## Overview

The Heltec Bitcoin Miner is a compact, low-power USB device featuring an ESP32-S3 chip delivering up to 387.5 KH/s hash rate. Designed for Bitcoin solo lottery mining, it supports daisy-chaining multiple units via USB-A for combined hashing power and centralized management. With WiFi/Bluetooth connectivity, a 0.96" display, and real-time power monitoring, it doubles as a desktop clock. Open-source and plug-and-play, it appeals to both crypto enthusiasts and ESP32 hobbyists, though it functions more as a lottery ticket miner rather than a traditional mining rig.

Review: Doesn't Actually mine anything at all just for show. - Got this for fun. Initially it didn’t even work. I was able to connect to the internet and add my BTC address but it wouldn’t finish the initial setup. Was driving me nuts. I was determined to make it work. Reset it probably about 3 or 4 times. Ended up changing the preset pool because the problem was the one that was preloaded into it didn’t work. I Love that this is pink and matches my desk setup excited to have this cool little miner on my desk that hopefully strikes gold & wins big. Have patience. It does work but because it comes without a manual you have to just kind of tinker with it and figure it out. You can reset it by pressing and holding the top button. Update- After verifying to see if it was actually mining it does not. It's just a toy for show an expensive miniature alarm clock. Definetly Returning. Total Scam. It's a lottery miner that doesn't actually mine anything at all.
Review: Outstanding quality - I love it thank you

## Questions & Answers

**Q: Do I need a computer or extra equipment for mining?**
A: No extra equipment is needed! Only a USB power supply (5V-3A) and a WiFi network are required. It takes only 3 steps to set up, making it easy for beginners.

**Q: Do I need multiple power supplies when using multiple miners?**
A: It supports chaining multiple bitcoin miners, requiring only one 5V-3A power supply. Hash rate is cumulative, and wiring is simple, resulting in very low deployment costs for multiple units.

**Q: How do I manage multiple solo miners?**
A: Through the official NMTech NMController tool (Windows client requires .NET Framework, web version requires Python environment), you can monitor hash rate, voltage, and operating status in real-time within the local area network.

**Q: Does the firmware need activation? What if I lose it?**
A: No activation required! The firmware can be downloaded from GitHub (NMminer1024) or the web-flash tool. If lost, it can be restored with one click using the tool, without any extra cost.

### ⭐⭐⭐⭐⭐ Outstanding quality
*by J***S on February 6, 2026*

I love it thank you

### ⭐⭐⭐ No instructions - but, I did figure it out.
*by J***M on January 26, 2026*

No instructions. Comes preset with some unknown BTC wallet address - so, if you do not set that to yours you will never get the reward if it does happen. Had to use trial and error to eventually figure it out. Nice to see the crypto prices on the screen as a monitor. Here is the process to get it working: plug into a USB power port, press the button on the top, change mobile phone wifi to the network name of the miner. The config page loads, there you can set the miner to use your home wifi network with the password, BUT once that is connected, you need to load the real config page by entering the miner's IP address (like: 192.168.1.100) into your browser and then you can edit the BTC wallet address. It is also good to see that it is operating. CAUTION: if you press the button on top of the miner you can inadvertently clear the wifi settings and then you have to do it all over again. It seems to have a mind of it's own. It either changes screens or resets config. I have noticed that if you unplug it and plug it back in, it reboots with its wifi and wallet settings retained.
