Raspberry Pi Servo HAT
16 Channel Servo Driver HAT for Raspberry Pi is a motor driver HAT from which one can control up to 16 motors simultaneously. If you're building a robot with a lot of moving parts, or if you need to monitor a lot of LEDs with PWM yields, the microcontroller's limited PWM yields will be a big problem. The most important thing you can do to solve this problem is to obtain a 16-Channel 12-Bit PWM/Servo Driver.
Features
- Adjustable frequency PWM up to about 1.6 kHz
- Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
- 3 pin connectors in groups of 4 so you can plug in 16 servos at once
- This board/chip uses an I2C 7-bit address
- 40-Pin GPIO accessibility
- I2C controlled and power supply connector
- Compatible with all the Raspberry Pi Models such as 4B, 3B+, 3, 2, B+, A, Zero, Zero W, etc.
Specifications
- Power supply: 5V OR 6V (power supply connector)
- Servo voltage: 5V
- Logic voltage: 3.3V
- Driver: PCA9685
- Control interface: I2C/GPIO
