Description
Description:The ATOM PWM is a single-channel PWM regulate 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 (eg, frequency of 5 kHz, duty cycle adjustment range 0-100%, resolution up to 13bit), and combined with the built-in WIFI & Bluetooth function, it can also easily achieve remote control. Supports UIFlow graphical programming for easy configuration of signal output and function expansion.
