M5Stack ATOMIC PWM Base

Description

The M5Stack ATOMIC PWM Base is a single-channel PWM adjustable DC driver base for ATOM series hosts. It supports DC 12-24V input and uses built-in MOSFET switch control to adjust the output signal duty cycle, with a maximum load capacity of 12V@100W.

The built-in DC-DC step-down circuit allows the input power to drive the load while powering the whole device, making deployment simpler. Combined with the Wi-Fi function of ATOM series controllers, it is suitable for remote control applications such as high-power DC motor speed control, LED brightness adjustment, power control, and industrial heating wire control.

Features

• ATOM compatibility: compatible with Atom-Lite, Atom-Matrix, AtomS3, and AtomS3-Lite.
• Single-channel PWM: low-latency PWM signal output for DC control applications.
• High-power output: high-power MOSFET with 12V@100W output capability.
• Grove expansion: reserves 1 x Grove expansion interface.
• Built-in DC-DC circuit: converts 12V to 5V for convenient device power supply.
• Protective casing: integrated design with a protective enclosure.
• Development support: supports Arduino and UIFlow workflows.
