ENG-CANSAT-V2-PINOUT

Power Section

This collect the information about the power circuitery for the Cansat V2 and the project.

The MCU Board (the Pico) is responsible from its own power regulation.

It can be powered from:

USB connector: so with 5V. That voltage will be made available on the USB pin.
VSYS pin : with a voltage from 3 to max 5.5V. A battery can feed that Pin

The MCU board (Pico) can be easily shutdown by placing its 3V3_EN pin to the ground.

Doing so, the Pico 3.3V DC/DC regulator will deactivates, shutting down the MCU and spare the battery power.

The following diagram show the power distribution with relation.
