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.
Important facts:
- The MCU board is responsible of its own voltage regulation.
- The MCU bpard regulated voltages are not shared with the Cansat Base board.
- The Cansat Base is responsible of its own voltage regulation.
- The Pwr Enable (on Cansat Base board) disable the voltage regulation on the Cansat Base and MCU board.
When USB plugged on MCU board : xxx
When USB unplugged : xxxx
When Lipo unconnected : xxx
When another voltage required : xxx
