Introduction


IOT:bit is an expansion board based on IoT for micro:bit. It uses ESP8266 as WIFI expansion board and serial port to communicate with micro:bit. It also has extended all available IO port of the micro:bit which is leaded by GVS and you can extent various 3V E-blocks as LED, photosensitive and servo by using it. At the same time, the IOT:bit with an on-board buzzer for outside sound and an on-board RTC clock for timing without power supply. Let's creating your own IoT by makecode!
