BBC micro:bit board#

From the micro:bit
page on Wikipedia:
for use in computer education in the UK.
The device is described as half the size of a credit card and has an ARM Cortex-M0 processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that form part of a larger 25-pin edge connector.
The micro:bit can be programmed in Microsoft MakeCode (a graphical language), Python, and Scratch.
The micro:bit is available from many vendors, and it clearly makes sense to shop for the best value (and the best value based on currency). Some options:
- micro:bit £13.50 from Pimoroni
- BBC micro:bit US$14.95 from Adafruit
- BBC micro:bit Go Bundle US$17.50 (with USB cable, battery pack and 2x batteries) also from Adafruit
- BBC Micro:Bit in Gift Box (Microbit) £11.75 from 4Tronix
Available micro:bit Robots#
Generally, unless stated otherwise the micro:bit board is not included with the robot kits.
M.A.R.S. Rover Robot for Microbit or Pi Zero#
 |
This is by far the most complicated micro:bit based robot available, and is certainly not an entry-level robot. This uses six micro metal gear motors and four servos.
It's included in the list here so you can see that a micro:bit robot need not be limited by any notion of the simplicity of its controller. You can purchase the rover for use with a Raspberry Pi Zero or a micro:bit (not included).
Bit:Bot#
 |
Introducing BitBot XL, taking the much-loved BitBot to the next level. We have made several changes, some subtle, some not so subtle, to give a much-improved experience of using and working with the BitBot. The Microsoft Makecode Extension for Bit:Bot also works for BitBot XL. It can automatically detect while running which version you have, or you can force it to be the Classic BitBot or the new XL.
MiniBit#
 |
The Minibit is the younger sibling of the popular and well-loved Bit:Bot. It comes ready-built (wheels need pushing on).
A Makecode extension is available. Blocks available for driving the motors, LEDs and optional ultrasonic sensor and line follower module as well as the other plugin breakouts.
:MOVE Mini#
 |
- :MOVE mini MK2 buggy kit £27.60
Robot:bit MK3#
 |
Version 1.3 of this popular kit now uses a removable ultrasonic sensor, that uses the same connector as used on the Minibit and BitBot XL. This allows the use of alternative addons, sich as the new BitFace, 5x5 FireLed Matrix and OLED.
Maqueen Lite#
 |
- micro: Maqueen Lite-micro:bit Educational Programming Robot Platform $24.90, with micro:bit based Gamepad (and 2x micro:bit): US$82.50
Maqueen is accessible to the Mind+ Programming platform now. Mind+ is a Scratch3.0-based graphical programming platform from DFRobot, supporting python, Arduino and other programming platforms. At present, Mind+ has been applied to all kinds of sensors, modules and related educational products.

This breakout is a simple and robust way to add ultrasonic distance sensing to your robot. Supported on BitBot XL, Pi2Go Mk2, Pi-Bug (v1.1 and later), Minibit and other 4tronix robots released from July 2019 onwards (including the Robobit Mk3, v1.3 onwards).
Available in standard and tall versions. The Tall version is intended for the BitBot XL with a Talon attachment. We recommend using the standard version for all other use cases.
