→Pico, PowerBoost and Cansat Kit
The {{pl|2271|Kit Cansat with Pico}} does have a footprint to receive an Adafruit PowerBoost 500 charger. This works exactly as described above but with all the wiring already done on the board.

Just place the PowerBoost under the board. Place it over the footprint drawed and solder it with the help of a PinHeader.

* Unplug the USB to make the LiPo powering the CanSat.

* The PWR_OFF connector (near the border of the board) can be fitted with a switch. Close the switch (so PWR_OFF tied to the ground) to deactivates/shutdown the PowerBoost.

* PowerBoost status LED:
* PowerBoost status LEDs are visible under the CanSat (see next section for description).
* PowerBoost LBO pin (Low Battery Output) is accessible on the breakout and may be useful to report battery state via radio.
{{ambox-stop|text=WARNING: Do not connect it directly to a 3.3V GPIO}}.
{{underline|About LBO pin}}: the LBO Pin is pulled high to '''BAT''' voltage (so 4.2V when battery is fully charged) in normal operation. When the battery voltage drops under 3.2VDC then the LBO pin is tied to the ground.
