Vision Master T190 Bitco Nerd Miner Development Board BTC Crypto Solo Lottery 117KH/s Win BTC with Low Power Consumption WiFi Connection Interface (No WiFi Cable)

I went to their website, then to their github repo, read their Readme, downloaded their tools, pushed the buttons as directed and nothing happens. Just reboots or hangs on a Heltec screen. Hooked it up to my PC and installed their software from the github tools folder, nothing would connect.They have screenshots of this well designed UI that will configure the device. Where is that tool? It's not either of the two suggested for download in github. That tool should probably ship with the device, and an instruction manual.This probably shouldn't be sold on Amazon, and definitely shouldn't have the words "user friendly" in the description

I purchased five of these Nerd Miner development boards, and overall, I’m very pleased with how they’re performing! One of them wasn’t flashed out of the box, so I had to do a bit of programming to get it up and running. If you have some basic knowledge of how to set up and connect to a public mining pool, you’ll be good to go.Once properly configured, these miners have been running smoothly for the past few weeks. The key is making sure you set them up with a reliable public pool. Performance has been solid, and the low power consumption makes them an efficient option for anyone looking to experiment with Bitcoin mining on a small scale.If you’re willing to put in a little effort to set things up, these devices work great. Definitely recommend for those who enjoy tinkering with hardware and learning about crypto mining!

I received mine and it wasn't loading into the bitcoin mining screen. I contacted the seller, they provided quick support that walked me through re-initialization and it works good now. It is running at 117KH/s.

Wi-Fi antenna missing from package second unit.

Returned. Don't waste your time.
