Description
Save batteries for your microcontroller projects.
Operation:
==========
- The SW connector powers on the MosFET so your micro controller gets power.
- The C-Pin on the 4-pin header shuts the mosfet down.
It is possible to have a RTC circuit with Alarm pin connected to the SW-connector to power on on a regular time basis and the micro controller can shutdown with the C-Pin after work is done.
