The M5Stack Base M5GO Bottom2 v1.3 expands the Core2 series with a 6-axis IMU, digital microphone, 500mAh battery and programmable RGB LEDs, alongside Grove and magnetic Pogo Pin connections for further expansion.
The M5StackBase M5GO Bottom2 v1.3 is an expansion base designed specifically for the M5Stack Core2 series. It features an onboard BMI270 6-axis IMU, LMD4020 digital microphone, and 500 mAh built-in lithium battery. Two HY2.0-4P expansion ports expose commonly used ADC, DAC, and UART peripheral pins for convenient connection to various sensor modules.
The base integrates 10 programmable SK6812 RGB LEDs on both sides. Combined with frosted light guides, they provide soft and even illumination. The bottom uses a Pogo Pin magnetic charging interface. When connected to a magnetic charging base, the onboard TP4057 charging management IC safely and steadily charges the built-in battery.
The Pogo Pin interface also exposes the host controller's I2C bus, supporting magnetic external expansion. Built-in magnets and LEGO-compatible mounting holes on the back allow seamless integration with LEGO structures.
