Raspberry Pi Servo Card

RPI-MDI-X2 5360-640px.jpg

Features

  • Raspberry Pi daughtercard
  • Fits on "old" Model B or "new" Model B Plus board
  • Three axis Servo PWM outputs (Servos not included)
  • Two PWM Controlled LEDs
  • I2C controlled 16-channel PWM controller PCA9685
  • 5 channels used as above (Three Servo outputs, 2 LED outputs)
  • PWM controller has internal built-in clock generator - no refresh required
  • Even though the Raspberry Pi has 3.3V I/O, the PWM outputs run at 5V - compatible with typical servos
  • Three switch inputs with on-board pull-ups which can be used as GPIO lines
  • 3X of 10 uF SMT capacitors on rear of board for PWM/Servo noise reduction
  • Right angle connectors for Low Profile
  • Recessed connectors for side connectors for smallest form factor
  • Very small size 1.4" x 1"
  • Jumper to use 5V from Raspberry Pi (if your power supply has sufficient capacity) or pads for external power or additional capacitance if needed
  • Python PWM - Adafruit driver
