Revision as of 03:01, 30 December 2019
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
Drivers/Example Code
- Github repo - Driver code
