Description

Base X is a specialized base compatible with LEGO EV3 motors. Its structural design is similar to BASE26, supporting multiple mounting methods and providing a LEGO connector base so it can be integrated into LEGO builds.

Base X can connect up to 4 LEGO motors simultaneously, supporting angle and speed reading and control. It also provides 2 servo interfaces for direct servo angle control, a built-in PDM microphone for sound acquisition, a UART interface, and a GPIO interface for flexible sensor connection.

The base includes a built-in 950mAh battery that can be charged through the M5Core USB Type-C port. To improve motor driving capability, it also provides a DC power jack for external 9-12V DC motor power input. Charging through the base is not supported.
