IoT Elecrow - 1

To make it easy to use for portable projects, a connector for 3.7 V Lithium polymer batteries and built in battery charging was added.

You don’t need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The board will automatically switch over to USB power when its available. The board comes pre-programmed with NodeMCU Lua.

You can order this ESP8266 IOT Board [DPO82666E] from ELECROW for $12.90. Further info you will find in the ESP8266 IoT Board Wiki.
