Atom Motion

SKU:K053

Description

Atom Motion is a servo & DC motor driving solution designed for the ATOM main control series. It integrates an STM32 control chip and uses I2C communication for control. It provides 4 channels for servo control and 2 channels for DC motor interfaces. It comes with a built-in 16340/18350 lithium battery (700mAh capacity). It features two HY2.0-4P expansion interfaces, with 4 pins exposed, allowing for the connection of external sensors and expansion devices. It is suitable for multi-servo/motor control scenarios, such as multi-axis servo robotic arm control or car motor driving.
