    • Awesome little miner.
Size: ESP32-WROOM-32
This thing is fire!!!! So easy to set up and use. NOTE: If you try to join the network to configure it and you can't join, keep trying. Sometimes it takes a few. Setup is simple. You need your Bitcoin receive address and you need to know your UTC time zone offset. Plug in, scan QR code that shows up. It will ask you to join a network and then load the configuration screen. Click on Join Network and select your home 2.4ghz network. Add in your bitcoin address in primary and back up and then save. It's already configured for the pool. Boom, you're done. Mess up configuration? There's two little buttons on the back. Hold the inside one for a few seconds with it on and your back in business. ... show more

    • Locked up on boot up, timer never ends.
Size: ESP32-WROOM-32
After only a couple days it locks up in boot mode. Can't get it out of that even with hard reset. Looked online and couldn't figure out how to get it back up and running. Need to be a software person and know which websites to use. Not so easy to maintain.

    • Pool connections!
Size: ESP32-WROOM-32
It worked well for a couple of weeks, but then the pool would not connect. Went through all the troubleshooting steps several times, including validating wallet address, firewall settings, hard resets and a firmware upgrade, but still it would not connect to any pool. Sometimes, it would get stuck on reboot. I give up.... ... show more
