Description The M5Stack ATOMIC PWM Base is a single-channel PWM adjustable DC driver base for ATOM series hosts. It supports DC 12-24V input and uses built-in MOSFET switch control to adjust the output signal duty cycle, with a maximum load capacity of 12V@100W. The built-in DC-DC step-down circuit allows the input power to drive the load while powering the whole device, making deployment simpler. Combined with the Wi-Fi function of ATOM series controllers, it is suitable for remote control applications such as high-power DC motor speed control, LED brightness adjustment, power control, and industrial heating wire control. Features ATOM compatibility: compatible with Atom-Lite, Atom-Matrix, AtomS3, and AtomS3-Lite. Single-channel PWM: low-latency PWM signal output for DC control applications. High-power output: high-power MOSFET with 12V@100W output capability. Grove expansion: reserves 1 x Grove expansion interface. Built-in DC-DC circuit: converts 12V to 5V for convenient device power supply. Protective casing: integrated design with a protective enclosure. Development support: supports Arduino and UIFlow workflows.
