Description This product is a PWM/servo expansion board based on . It can expand 16- servo control or PWM output through the PCA9685 chip, and each channel has a 12-bit resolution. With the I2C interface for control, it requires no other pins. The onboard 5V voltage regulator chip can be connected to the battery, and the maximum output current is 3A. It is suitable for controlling robot arms and various servo robots. With the right-angle pin header, it allows servos to be connected even when stacked up. Needless to say, it is powerful enough in most cases, but it is not so good at providing precise PWM output. You may have tried to control a robot arm or a hexapod walker by using Pi, but in the end, become frustrated due to the limited number of PWM outputs and the jittering servos. Now you get a new option to realize your ideas, we prepare this useful Servo Driver HAT for you. Standard 40PIN GPIO extension header, supports series boards, Jetson Nano I2C controlled, uses only 2 pins Up to 16-channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales) Integrates 5V regulator, up to 3A output current, can be powered from battery via VIN terminal Standard servo interface, supports commonly used servos such as SG90, , , etc. Reserved I2C control pins, allows working with other control boards Power supply: 5V (Pi connector) OR 6V~12V (VIN terminal) Servo voltage: 5V Logic voltage: 3.3V Driver: PCA9685 Control interface: I2C Dimension: 65mm x 30mm Mounting hole size: 3.0mm Color: blue Material: PCB Package contents: 1 x Servo Driver HAT (B) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
