The M5Stack Base X expands M5Core with support for up to four LEGO EV3 motors, dual servo outputs, built-in microphone, GPIO/UART connectivity, and a rechargeable battery, making it ideal for LEGO-compatible robotics and custom sensor projects.
The M5StackBase X is a specialized base compatible with LEGO EV3 motors. Its structural design is similar to BASE26, supporting multiple mounting methods, and additionally providing a LEGO connector base that allows Base X to be easily integrated into LEGO builds.
Base X can connect up to 4 LEGO motors (RJ11) simultaneously, supporting angle/speed reading and control, perfectly compatible with the original motor functions.
In addition, the base provides 2 servo interfaces for direct servo angle control, a built-in PDM microphone for sound acquisition, a UART interface (16/17), and a GPIO interface (26/36), making it more flexible for connecting various sensors in different scenarios. The base has a built-in 950mAh battery that can be charged via the M5Core’s USB Type-C port to extend battery life. To improve the driving capability of the interfaces, the base is equipped with a DC power jack for powering motors using an external 9 ~ 12V DC power supply (charging through the base is not supported).
