Description

The M5Stack Base AAA is a compact AAA battery holder and dry battery base for the M5Stack 5 x 5cm system. It uses four AAA dry batteries, steps 6V down to 4V through DC-DC, and supplies power to the BUS BAT pin. The holder also provides a physical power switch, so power can be fully turned off to reduce dry battery drain during storage or transport. With PORT.B, PORT.C, a 1 x 12P 2.54 pitch female header, side mounting holes, bottom magnetic fixing, and two embedded brass nuts, the base is designed for portable prototypes and fixed installations.

Note: AAA batteries are not included.
