If you have a NodeMCU ESP8266 v1.0 you probably know it's the perfect little size for IoT projects. This LiPo backpack makes very easy the charge of a LiPo battery instead of soldering more boards, this little PCB sits on top of the NodeMCU ESP8266 v1.0 and allows a LiPoly/LiIon battery to plug in. When the NodeMCU ESP8266 v1.0 USB port is powered, the battery is recharged automatically. Unplug the USB port and the NodeMCU ESP8266 v1.0 will switch over to the rechargeable battery.
