“If you want a small solution to use up to 16 servos, this little feather board is for you. Can be controlled with both arduino or Raspi boards via i2c communication.”
“Its a wonderful small fitting to the feather boards PWM device. I use it with the adafruit-feather-m0-wifi-atwinc1500 for an RC-receiver with up to 8 channels. Soon I will store the software on 'github'.”
