Specification: Origin: Mainland China Type: Drive IC Condition: New Model Number: PWM Servo Driver Product Size: 61.00x25.00x3.00mm/2.4x0.98x0.12inch 1. It is an i2c controlled PWM driver with a built-in clock. This means that, unlike the TLC5940 series, you don't need to continuously send signals to hogs your microcontroller, it runs completely free! 2. It is 5 V compliant, which means you can control it from a 3.3 V microcontroller and still safely drive outputs up to 6 V (useful when you want to control white or blue LEDs with 3.4+ positive voltage). 3. 6 address select pins so you can connect up to 62 address select pins on a single i2c bus for a total of 992 outputs - that's a lot of servos or LEDs! 4. Adjustable frequency PWM up to approx. 1.6KHz. 5. 12-bit resolution per output - providing over 4us of resolution at a 60Hz update rate. 6. Configurable push-pull or open-drain outputs. 7. Output enable pin to quickly disable all outputs. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1* Servo Control Module Kit (Not Soldered) 1.Built-in Clock: This 12 bit PWM servo driver features a built-in clock, eliminating the need for continuous signal transmission from your microcontroller.Enjoy the freedom of a self-running module without occupying your microcontroller's resources. 2.5V Compatibility: The 12-bit servo driver board is designed to be compatible with the 5V standard, allowing control from a 3.3V microcontroller while safely driving outputs up to 6V. Suitable for controlling high forward voltage white or blue LEDs with a voltage of 3.4+. 3.Address Select Pins: This motor drive expansion board with 6 address select pins, you can connect up to 62 address select pins on a single i2c bus, providing a total of 992 outputs.Take advantage of this feature for extensive servo systems or LED control. 4.Adjustable Frequency PWM: The motor drive shield board enjoy adjustable frequency PWM up to approximately 1.6KHz, allowing precise control over your servos or other devices.Customize the frequency according to your specific requirements. 5.12-Bit Resolution: Each output of this PWM servo motor driver offers a 12-bit resolution, providing over 4us of resolution at a 60Hz update rate.Configure the outputs as either push-pull or open-drain based on your application needs.
