The ATOM PWM from M5Stack is a single-channel PWM DC Driver with built-in MOSFET load capacity up to 12V@100W, suitable for high-power DC motor PWM speed control and industrial heating wire control applications.

Using ATOM LITE as the core controller (built-in ESP32), it has a wide PWM dynamic adjustment range (e.g., frequency of 5 kHz, duty cycle adjustment range 0-100%, resolution up to 13bit), and combined with the built-in WIFI function, it can also easily achieve remote control.

Supports UIFlow graphical programming for easy configuration of signal output and function expansion.

Atom Lite included!

Arduino Example


#define SIGNAL 22

int freq = 10000;
int ledChannel1 = 0;
int resolution = 10;

void setup() {
  ledcSetup(ledChannel1, freq, resolution);
  ledcAttachPin(SIGNAL, ledChannel1);

void loop() {

    for(int i=0; i < 500; i++){
      ledcWrite(ledChannel1, i);

    for(int i=500; i > 0; i--){
      ledcWrite(ledChannel1, i);
