Core2 Expansion Base with 500mAh Battery, MPU6886 IMU, Digital Microphone, and RGB LEDs
The M5Stack A014-C Base M5GO Bottom2 is an expansion base designed specifically for M5Stack Core2. It integrates an MPU6886 6-axis IMU, LMD4737 digital microphone, 500mAh lithium battery, and 10 programmable SK6812 RGB LEDs. The built-in motion sensor and microphone extend Core2 with motion and audio-input capabilities, while the dual RGB light bars provide programmable visual indication and lighting effects.
Two HY2.0-4P expansion ports expose ADC, DAC, and UART signals for connecting sensors and peripheral modules. A bottom pogo-pin interface supports magnetic charging through the onboard TP4057 charging IC and also exposes the Core2 I2C bus for compatible magnetic expansion accessories. Integrated magnets and LEGO-compatible mounting holes simplify mechanical installation in portable controllers, IoT devices, educational projects, and custom Core2 systems.
