M5Stack ATOM TailBat is an external battery accessory designed for the M5ATOM. The TailBat module directly supplies power, enabling the M5ATOM to be used in mobile applications. Since the TailBat has been designed simply to add battery power, it will not affect the original Grove Connection mode and USB functionality. The built-in 190mah battery can only be easily charged through the USB Type-C interface.
The M5Stack ATOM TailBat is also compatible with the M5Stick, M5StickC, M5StickV, and M5Camera.
