GPIO breadboard extension board for Micro:Bit enables direct connection to the breadboard. The connection is very intuitive – you will have everything set up in seconds. It makes it easy to connect sensors and modules. An additional advantage of this board is the separate 5V and 3.3V supply pins. This makes it possible to use larger groups of sensors and modules. In addition, the board is equipped with a micro USB power connector. We also have UART/I2C communication pins in two groups.

The TX and RX pins are used for the Serial UART protocol. TX and RX refer to the Transmitter and Receiver.

The SDA and SCL pins are the pins for the I2C protocol. These pins refer to Serial Data and Serial Clock.
