iot:bit Board: help your pupils progress with the Internet of Things
The ESP8266 module included in the IoT extension board for micro:bit enables you to create many connected projects and to introduce your pupils to the Internet of Things. Your micro:bit board inserts easily in the slot provided for this purpose. Simply open your MakeCode programming editor to launch a new experiment in your classroom.
The RTC timing is powered by a simple CR1220 button cell (not included). The iot:bit board can be powered via a USB port.
An extension board for adding many devices
The iot:bit extension board breaks out all the ports on your micro:bit as GVS connectors, which makes it easy to connect many micro:bit compatible modules using simple 3-wire GVS cables, including Octopus modules. The extension board also features SPI and I2C interfaces for adding devices such as an OLED display or a BME280 temperature sensor.
It’s also worth noting that the mounting holes on the board are compatible with LEGO bricks, so children can design fun creations they can identify with!
