Main features of the M5Stack Base Dual 16340 battery stand
- M5Stack Battery Base : Provides mobile power to compatible controllers and embedded devices
- Two 16340 batteries : two cells with a capacity of 700 mAh each provide a total capacity of 1400 mAh
- Parallel connection of cells : allows for increasing the available capacity while maintaining the voltage typical of a single Li-Ion cell
- INA226 Monitor : allows real-time voltage, current and power measurement
- I2C communication : allows the master device to read parameters from the power monitoring system
- DW01A protection system : is responsible for protecting the batteries during operation
- Overcurrent protection : increases system safety in the event of excessive load
- Reverse polarity protection : reduces the risk of module damage due to incorrect cell assembly
- Slide Power Switch : Allows you to quickly turn the power on and off without disconnecting the batteries
- Two HY2.0-4P connectors : provide GPIO and UART interfaces for cooperation with sensors and peripheral modules
- Compact design : 54 x 54 x 21 mm housing fits well in portable devices
Pinout and compatibility of the Base Dual 16340 module with M5Stack
The Base Dual 16340 uses a 30-pin M5-Bus connector , which provides power, communication, and battery monitoring lines. The bus provides the INA_SDA and INA_SCL lines for the INA226 chip, RXD and TXD, 3.3V and 5V power supplies, BAT, and HPWR lines, among other things. This allows the base to be integrated with compatible M5Stack controllers using the M5-Bus system. Two Grove HY2.0-4P connectors are also available. PORT.B provides GND, 5V and the PORT.B OUTPUT and PORT.B INPUT lines, while PORT.C provides GND, 5V, and the TXD and RXD serial communication lines. This solution allows you to simultaneously power the device and expand the project with additional sensors or peripheral modules without the need for an additional connection board. Before connecting to a specific M5Stack controller, consider the M5-Bus pins used by the project to avoid conflicts between modules.
Two Grove interfaces provide access to GPIO and UART and allow you to connect additional sensors, modules and peripherals.
The M5Stack Base Dual 16340 will prove to be a mobile power source for M5Stack projects.
