Product Description

4tronix Bit:Bot XL Robot for BBC micro:bit

Introducing BitBot V2, 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.

Note: Does not Include BBC micro:bit. The BBC micro:bit can be purchased separately here.


  • Chunky wheels with rubber tyres for maximum grip
  • Microbit mounted vertically
  • Line sensors no longer share pins with the Microbit buttons - removes all Bluetooth pairing issues and allows use of buttons in your code
  • Pen holder is fitted as standard. Mounted directly over the pivot point for better drawing
  • Indicator LEDs added for line follower sensors
  • Makecode extension has been changed so code is compatible with both Classic and V2 versions
  • Buzzer now connected on Pin 0 so you can play music through it
  • 2 micro-metal gear motors. Motor gearboxes fully covered (minimises fluff in the gears)
  • Front ball caster
  • 12x Smart RGB LEDs in 2 sets of 6 along the arms either side: Select any colour for any pixel, produce stunning lighting effects as your Bit:Bot moves around.
  • 2x digital line following sensors: Code your own line-following robots and race them to see whose code produces the fastest lap time!
  • 2x analog light sensors (front left and front right): Your Bit:Bot XL can be programmed to follow a light source such as a torch, or you could code it to go and hide in the darkest place it can find.
  • 1x Buzzer: So you can make beeping sounds or music whenever you want.
  • Powered from integrated (3x)AA battery holder with on/off switch and blue indicator LED
  • Easily plug your BBC micro:bit in and out using the vertical edge connector
  • Expansion connections at the front for accessories


  • Dimensions: Approximately 10% larger in length and width than the Classic Bit:Bot
  • Uses standard breakout connector for ultrasonic breakout
  • 2x GVS outputs provided for potential servo usage with 5V power
Accessories for the 4tronix Bit:Bot XL

Awesome service with super fast delivery. The chat option really helped me choose the products, know they were in stock and would be delivered in time. The items were posted the same day and I couldn't believe it when they arrived from Perth to Melbourne in 3 days! Thanks for your wonderful support - our students were able to complete their robotic projects in time.
