Plug in
any
Feather mainboard you want into the center, and you're good to
go! The Crickit is powered by seesaw, our I2C-to-whatever bridge firmware. So
you only need to use two I2C 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.
The only thing that is
not
managed by seesaw is the audio output. We provide a
small jumper you can solder to connect the audio amplifier to the first analog
pin. On our Feather M0's this is a true analog output (DAC) and you can play
audio clips with CircuitPython or Arduino. Other Feathers
may not have a
DAC!
In that case, you can solder a wire to jumper the audio amp to a PWM pin.
You get to use all the non-I2C signal pins on your feather and get a boat-load
of extra in/out pins, motor controllers, capacitive touch sensors, a NeoPixel
driver and amplified speaker output. It complements & extends your Feather so
you can still use all the goodies, including stacking FeatherWings on top. But
now you have a robotics playground as well.
You get:
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 sensors with alligator-pads
8 x Signal pins, digital in/out or analog inputs
1 x NeoPixel driver with 5V level shifter - The NeoPixels are buffered and
controlled by the seesaw chip
1 x Class D, 4-8 ohm speaker, 3W-max audio amplifier - the audio input
pin is available as a solder-able pad for your configuration, you can
connect it to your Feather's DAC or PWM output as you desire.
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.
