Description
Base Dual 16340 is a compact battery base module for M5Stack controllers that supports two 16340 rechargeable cells in parallel to provide stable battery power to the main system. The module integrates power-path management, power-switch control, overcurrent and reverse-polarity protection, and battery status monitoring, helping to monitor voltage, current, and power in real time for power-management and energy-analysis tasks.
Inside the module is an INA226 current and voltage monitoring chip that communicates with the host through an I2C interface. It also provides two Grove expansion interfaces, making it easy to connect various sensors and peripheral modules for battery expansion of M5Stack devices or standalone embedded applications.
