M5 Stack Atomic Motion Base v1.2 is a high-performance servo and DC motor drive base specifically designed for the Atom main control series. It deeply integrates power control, intelligent expansion, and safety protection functions to provide a one-stop solution for multi-domain development. The product is equipped with 4-channel servo interfaces and 2-channel DC motor interfaces, which can precisely drive various actuators; two HY2.0-4P interfaces support the rapid connection of various sensors such as temperature, humidity, and light, easily realizing device function expansion.

In terms of communication, it uses a stable I2C communication protocol, combined with STM32+RZ7899 control chips, ensuring stable driving, efficient data transmission, and low latency.

In terms of the power supply system, it has a built-in rechargeable 900mAh 18350-specification lithium battery, equipped with a DW01-A high-precision single-cell lithium battery protection chip and an INA226 current/voltage detection chip to form a dual safety protection system. The DW01-A chip has overcharge, overdischarge, and short-circuit protection functions to comprehensively protect battery safety; the INA226 chip monitors the battery voltage, current, and power in real-time to provide data support for the stable operation of the system. In addition, the product integrates overload protection and convenient charging functions, combined with an independent power switch and a removable battery design, making it flexible and safe to use.

Atomic Motion Base v1.2 features a highly integrated and dual-protection design, making it particularly suitable for application fields that require a balance of safety, scalability, and portability.
