Description
The Waveshare Servo Driver HAT for Raspberry Pi is a robust and compact PWM expansion board, engineered for precise control over multiple servos. Utilizing the PCA9685 controller, it delivers up to 16 independent PWM/servo outputs, each with a high-resolution 12-bit (4096 steps) signal, significantly enhancing control accuracy compared to direct GPIO methods. This dedicated hardware offloads PWM generation, ensuring smooth, jitter-free servo movements.
Designed for seamless integration, the HAT features a standard 40-pin GPIO header, ensuring compatibility with various Raspberry Pi series boards and the NVIDIA Jetson Nano. It includes an onboard 5V regulator capable of supplying up to 3A, allowing for direct powering of multiple servos. Furthermore, the board supports external power input via its VIN terminal, accommodating systems requiring higher current or specific voltage requirements. Communication is handled efficiently through a two-pin I2C interface, minimizing GPIO usage on the host device.
