Feature: 1. Communication with Built-in PWM Driver and Clock: Enjoy the convenience of communication, which eliminates the need for constant signal transmission from your microcontroller. This board features an integrated PWM driver and clock, setting it apart from the TLC5940 series. 2. 5V Compatibility and Safe 6V Output: With its 5V compatibility, you can control the board using a 3.3V microcontroller while safely driving outputs up to 6V. Additionally, it supports controlling white or blue indicator lights with voltages higher than 3.4V+. 3. Addressable Pins for Extensive Expansion: The six address selection pins allow you to connect up to 62 driver boards to a single bus, providing a total of 992 PWM outputs. This exceptional scalability makes it ideal for large-scale projects requiring extensive resources. 4. Adjustable Frequency PWM Output: The board offers approximately 1.6KHz adjustable frequency PWM output, enabling precise control and smooth operation in a variety of applications.
