Additionally the FM24C02 internal eeprom chip(256KB-EEPROM)can be used to store vital data even when the device is off. A 1150mAh lipo battery keeps the device going for long periods and battery life can be further preserved by using the RTC(BM8563)to set the device into deep sleep and wake it up again when needed。Three HY2.0-4P expansion ports are included which allow for building complex projects using the existing sensors in the M5Stack ecosystem.

The PbHub extension mechanism that allows it to control IO using a single-bus data transfer wires is embedded inside the Mega328 with pre-programmed functionalities such as: GPIO, AD and DA to enable digital read and write and analog read and write features. In this case, the PbHub is sometimes not necessary for applications that doesn't require such specific features or require features outside of the scope of the IO pins both for analog and digital IO. For example, if some project requires PWM functionalities - the PbHub won't be useful for such application as there is no support for PWM.*
