The Wemos D1 Mini is my favorite ESP8266 board. It is small, cheap, easy to use, and you get many compatible shields. The prototype shield I like most. Unfortunately, these Wemos are not perfect when it comes to power consumption during deep sleep, and they do not offer an external antenna. That is what we will change in today’s lockdown quickie.
