The Kitronik Compact All-In-One Robotics Board for BBC micro:bit features 2 Dual H Bridge Motor Driver ICs and 8 servo outputs, all controlled from the BBC micro:bit using the I2C protocol via a 16 channel driver IC. The custom MakeCode blocks make using I2C easy, even for novice users.
The Link header breaks out all the usable pins from the BBC micro:bit, and is designed to allow 2.54 mm pitch pin header to be easily soldered into place. The 17 available I/O pins allow other input devices, for example, sensors, or output devices, such as ZIP LEDs, to be added to the board. The I2C communication lines are also broken out (Pins 19 & 20), which means other I2C compatible devices can also be added to the board and controlled by the BBC micro:bit.
Power is provided via either a terminal block or servo style connector. The supply is then controlled by an on/off power switch to the board. There is also a green LED to indicate when the board is turned on. The board then produces a regulated 3.3 V supply which is fed into the 3 V and GND connections to power the connected BBC micro:bit. This removes the need to power the BBC micro:bit separately. The 3 V and GND pins are also broken out on the Link header, which means external devices can also be powered.
To use the compact robotics board, the BBC micro:bit should be inserted firmly into the edge connector, with the LEDs and buttons visible from the front.
