Microcontroller Supporting GPS/Accelerometer/Servos?

by jkanalakis on Sat Aug 10, 2019 8:14 pm

I'm seeking advice with my search for the smallest possible microcontroller to take input from GPS and accelerometer modules and drive 4 servos and a solenoid in realtime. I have Crickit for CPX and Crickit for Pi; I love both and they functionally work, but both are pretty large and overkill with all of the other great functionality packed-in. And by large, I mean the CPX has a workable size for my project, but the Crickit for CPX exceeds my working footprint.

I figured that I could choose one from the many Adafruit supplied microcontrollers to take the signal inputs from GPS/accelerometer and the drive the 4 servos and solenoid. Between Arduino, Feather, Trinkets, and Micro:Bit, I can't tell which is best suited. Any suggestions?

Related project components:

Accelerometer https://www.adafruit.com/product/1231
Solenoid https://www.adafruit.com/product/2776

Thank you,

Depending on the number of pins you need the Feather and the Itsy-Bitsy are good choices.

Thank you for the helpful tip. I only need to power 4 servos. This looks like a promising option:
8-Channel PWM or Servo FeatherWing Add-on For All Feather Boards https://www.adafruit.com/product/2928

It looks to be sold out on Adafruit.com, so I might have to source the component from eBay for now. I'll try pairing it with Adafruit Feather 32u4 Bluefruit LE or the Adafruit Feather 32u4 Adalogger and run some experiments with the Adafruit PWM Servo library (https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library).

I really appreciate the advice.

Take a look at our distributor network. They may have stock that we are out of.
