Students, hobbyists and electronic enthusiasts looking to control motors, servos, solenoids and more using the BBC micro:bit mini PC might be interested in a new arrival at the Adafruit store which takes the form of the CRICKIT for micro:bit.
Simply plug in your micro:bit mini PC into the 40 pin edge connector and start controlling. “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.”
Features and specifications of the CRICKIT for micro:bit include :
4 x Analog or Digital Servo control, with precision 16-bit timers
2 x Bi-directional brushed DC motor control, 1 Amp current limited each, with 8-bit PWM speed control (or one stepper)
4 x High current “Darlington” 500mA drive outputs with kick-back diode protection. For solenoids, relays, large LEDs, or one uni-polar stepper
4 x Capacitive touch input sensors with alligator-pads
8 x Signal pins, can be used as digital in/out or analog inputs
1 x NeoPixel driver with 5V level shifter – this is connected to micro:bit pin #16 so you can use MakeCode’s built-in NeoPixel control
1 x Class D, 4-8 ohm speaker, 3W-max audio amplifier – this is connected to micro:bit pin #1 which is the default audio output
Adafruit explains 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.” For more details and purchasing options jump over to the official Adafruit online store where the CRICKIT for micro:bit is now available to purchase priced at $29.95.
