Adafruit CRICKIT for micro:bit
Sometimes you want your micro:bit to be able to control and interact with more things, and 5v things at that!
That's why Adafruit designed Crickit - That's our Creative Robotics & Interactive Construction Kit. It's an add-on to the BBC's micro:bit that lets you #MakeRobotFriend using MakeCode or Arduino.
Plug your :bit into the 40 pin edge connector and start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends micro:bit so you can still use all the goodies on the :bit, but now you have a robotics playground as well.
Please note at this time that MicroPython is not supported yet, just MakeCode & Arduino!
The Crickit is powered by seesaw, our I2C-to-whatever bridge firmware. So you only need to use two data pins to control the huge number of inputs and outputs on the Crickit. All those timers, PWMs, sensors are offloaded to the co-processor.
All are powered via 5V DC, so you can use any 5V-powered servos, DC motors, steppers, solenoids, relays etc. To keep things simple and safe, we don't support mixing voltages, so only 5V, not for use with 9V or 12V robotic components.
Please note this robot board does not require any soldering but you will need a power supply and a micro:bit to go along with the Crickit, and these are not included! You can also use a battery cage with a 2.1mm plug.
Since you'll be working with high-current devices, we wanted to have a good solid power supply system that minimises risk of damage. The power supply has an 'eFuse' management chip that will automatically turn off if the voltage goes above 5.5V or below 3V and has over-current protection at 4A. Every motor driver has kick-back protection. We think this is a nice and durable board for robotics!
