M5Stack ATOM PWM Kit (FDD8447L) [Discontinued]

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!
