Localized IOT – Hardware Node

Each node in Localized IOT consists of a base board – using an ESP8266 MCU as its core. The ESP8266 carrier board is the Wemos D1 Mini.

The mini was chosen for its small size and easy intergration onto a carrier base board. Plus the mini has the serial interface and everything needs to get the ESP to work. It is one less thing I have to build.
