Atomic Motion Base v1.1 is a servo and DC motor driver base designed for the ATOM controller series. The product provides 4-channel servo interfaces and 2-channel DC motor interfaces, while also featuring two Grove interfaces for easily connecting various sensors and expansion devices. In terms of communication, it uses the I2C protocol and is equipped with an STM32 controller chip to ensure stable data transmission. For power supply, it integrates an 18350 lithium battery (900mAh) and uses an INA226 current/voltage detection chip to monitor battery voltage, current, and power in real time, ensuring stable and safe power for the system. Additionally, it includes an overload protection feature to prevent damage to the device from excessive loads. The product also includes a battery charging function to conveniently charge the battery, extending usage time. An independent power switch is mounted for easy user operation of the power on/off function. This product is suitable for multi-servo control, robotics development, smart device prototyping, and automation experiments.
