Had promise but came up short

Has promise but hampered by really poor documentation and support. The convoluted board/driver addition process basically doesn't work. The only way I was able to get anything to upload to the board was using NodeMCU 1.0 as the board. A big drawback is the fact that the board has a really bright amber LED which flashes very fast and constantly if you don't have a battery plugged in. A battery is not required for operation, but apparently the manufacturer thinks you urgently need one. There are a ton of other options in this space...I'd look elsewhere.
