REKA:BIT Robotics Board for micro:bit

The REKA:BIT is a compact robotics expansion board for your BBC micro:bit (not included), providing a huge range of useful features, ports and onboard protection to help you make awesome micro:bit robotics projects. It's the smaller sibling of the popular EDU:BIT. The helpful features (see below) such as the GPIO and motor indicator LEDs as well as test buttons and easy-to-use Grove ports make this a great choice for your first robotics project or educational environments, where fiddling with components and wires can be frustrating and distract students from learning how to code. Program your REKA:BIT with the Microsoft MakeCode Editor. Just add REKA:BIT MakeCode Extension and you’re good to go. If you’re a beginner, you can start with the block programming mode; simply drag, drop and snap the coding blocks together. For more advanced users, you can easily switch to JavaScript or Python mode for text-based programming. The REKA:BIT comes with a USB power/data cable, 4xAA battery holder, grove header cables, screwdriver and building block lift arm + pin. All you need to add is a micro:bit board (not included).

Features Your micro:bit simply slots into the onboard connector, which then connects it to the many features on the board:

* 2x Motor terminals (connected to an onboard motor driver chip

* Drive two DC motors (1A continuous, 1.5A peak (< 5 seconds))

* 4x Servo headers

* Motor test buttons (no code required)

* Motor status LED indicators

* GPIO status indicators

* 6x Grove ports for adding sensors and other devices

* 2x Onboard addressable RGB LEDs

* Barrel Jack DC power input (3.6V - 6V)

* Undervoltage (LOW) indicator & protection

* Over-voltage (HIGH) indicator & protection

* On/off switch

* Power indication LEDs

* Dimensions: 10.4mm x 72mm x 15mm

The REKA:BIT features a co-processor to handle multi-tasking more efficiently. Playing music while controlling up to 4x servo motors and 2x DC motors, animating micro:bit LED matrix and even lighting up RGB LEDs in different colours, all at the same time, is not a problem for the REKA:BIT.
