Atom PWM

SKU:K065

Description

Atom PWM is a single-channel PWM adjustable DC driver with a built-in MOSFET capable of handling up to 12V@100W. It is suitable for applications such as high-power DC motor PWM speed control and industrial heating wire control. Using Atom-Lite as the core controller (built-in ESP32), it offers a wide range of PWM dynamic adjustment (e.g., at a frequency of 5 kHz, the duty cycle adjustment range is 0-100%, with a resolution of up to 13 bits). Combined with the built-in WIFI function, it can easily achieve remote control. It supports UIFlow graphical programming, making it easy to configure signal output and function expansion.
