This Bitcoin Miner BTC V2 NMMiner is a fun and interesting device, especially for educational and learning purposes. It works as advertised once you understand how to set it up, but it’s worth noting upfront that there are no printed instructions included in the box. That said, there is plenty of helpful information available online. A quick Google search and a few YouTube videos were enough to get a solid understanding of how it works, how to connect it to Wi-Fi, and how the different mining modes function. If you’re comfortable doing a bit of research, the setup isn’t too difficult. The 2.8-inch display is clear and informative, showing hashrate, status, and other key details in real time. I really like how quiet and low-power it is—it runs silently and doesn’t generate noticeable heat, which makes it perfect for a desk, classroom, or learning environment. Performance-wise, this is clearly meant for learning and experimentation, not serious mining profits, and that’s exactly what it delivers. The multi-mode options (solo, pool, lucky mining) are great for exploring how mining concepts work on an ESP32 platform. Overall, it’s a great educational tool for anyone curious about Bitcoin mining and blockchain basics. Just be prepared to rely on online resources instead of included instructions. With that in mind, it’s a solid and enjoyable device for beginners, hobbyists, and tech learners.

To begin, no instruction manual was included. I have been trying to set this miner up using YouTube / other resources, but unsuccessfully. It comes with the miner, the hard case for the miner, a USB-C cable, and what appears to be a motherboard header cable, like the ones you use to connect the power button on your PC case to your PC motherboard. No other miners that I've found online have this extra cable and I'm not sure how to use it. When the device turns on, it presents you with a QR code and instruction to connect to a wifi network to complete the setup. Although I can see the wifi network and connect to it, it does not require a password like it says on screen. Once you connect, nothing happens on either my phone or the device.

Trash. I bought 3 of these as gifts. We couldn’t make any of them work. Could not connect to it or connect it to WiFi no matter how many times we tried or re-booted. Never was able to progress past the first screen. Should have read the other REAL reviews before purchasing. Also, no instructions or link to instructions. Have to rely on YouTube videos of other brands to attempt problem solving.

Cute little miner. Easy to put together. I like that it came in pieces, it was a fun activity setting it up.

Shoddy Product - Can't assemble because small bolts are just a little too short. Three out of four on the face were not long enough to reach the stand offs. These have to go through the front acrylic piece and then the width of the board itself.

Cool like device. Found a video on youtube explaining it since it doesn't bring instructions. Does what it says.
