Atom Motion
Description
ATOM Motion is a steering gear & DC motor drive base designed for the ATOM device series. It has an integrated STM32 control chip with an I2C communication control mode suitable for device communication. The base includes 4-channel steering gear and 2-channel DC motor interface. Integrated 16340 lithium battery (with capacity of 700mAh). Two-way HY2.0-4P interface expansion and 4 LED out pins which can be used to connect some sensors and expansion equipment. Suitable for multi-steering gear/motor control scenarios, such as multi-axis steering gear manipulator control or trolley motor drive.
