ATOM TailBat

by M5Stack

A handy plug and play external 190mah lithium battery for use with ATOM development boards.

A single click of the physical button will turn on the power, and a double-click will turn it off. The TailBat just provides power, so it won't affect the original GROVE Connection mode and USB functionality. The battery can only be charged through the USB-C interface, not through the GROVE interface.
