Atomic Motion Base

SKU:A090

Description

Atomic Motion Base is a servo and DC motor driver designed specifically for the ATOM series controllers. It integrates an STM32 control chip internally and uses I2C communication for control. Atomic Motion Base provides 4 servo channels and 2 DC motor interfaces, offering convenience for scenarios that require control of multiple servos or motor drivers, such as multi-axis servo robotic arms or small car motor control.

Internally, Atomic Motion Base integrates a 16340 lithium battery with a capacity of 700mAh or 18350 lithium battery with a capacity of 1000mAh, enabling independent power supply and convenient portability without the need for an external power source. Additionally, Atomic Motion Base provides two HY2.0-4P interface extensions, which expose 4 PIN pins that can be used for connecting sensors and other expansion devices.
