Base M5GO Bottom2 is an expansion base specially designed for Core2. It integrates an MPU6886 6-axis motion sensor, a digital microphone (SPM1423), and a 500mAh lithium battery. Two HY2.0-4P expansion ports bring out common ADC/DAC/UART pins, allowing connectivity to various types of sensors.
On each side of the base are 10 programmable RGB lights (SK6812) with frosted light diffusing strips for soft and comfortable lighting effects. The bottom is equipped with a pogo pin magnetic charging interface, which, when attached to a charging base, allows current to safely flow into the internal battery through the built-in TP4057 charging chip. In addition to charging, the pogo pin interface also brings out the main control I2C bus, making it possible to magnetically connect external expansions.
It has an embedded magnet and a LEGO-compatible back hole design for seamless integration with other LEGO structures.
