Motion Base v1.1 is a servo and DC motor drive base designed specifically for ATOM main control series. The product provides 4-channel servo motor interface and 2-channel DC motor interface, as well as two onboard Grove interfaces, which can facilitate the external connection of various sensors and expansion devices. In terms of communication, I2C communication method is adopted, and STM32 control chip is used to stable data transmission. In terms of power supply, it is equipped with a built-in 18350 specification lithium battery (900mAh) and an INA226 current or voltage detection chip to monitor battery voltage, current, and power in real time, ensuring the safety and stability of system power supply. At the same time, the integrated overload protection function effectively prevents equipment from being damaged due to excessive load. The product also has a battery charging function, ensuring that the battery can be easily to extend its usage time. The onboard power switch design facilitates users to switch on and off the power supply. This product is suitable for multi servo control, robot development, intelligent device prototype design, and automation experiments.
