M5Stack K065 ATOM PWM Kit

m5Stack K065 ATOM PWM Kit is a single-channel PWM regulated DC driver with a built-in MOSFET load capacity up to 12V @ 100W. This device is 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 5kHz, duty cycle adjustment range 0-100%, resolution up to 13bit). When combined with the built-in Wi-Fi® and BLUETOOTH® function, it can also quickly achieve remote control. The m5Stack K065 ATOM PWM Kit supports UIFlow graphical programming for easy signal output and function expansion configuration.
