The {{pl|2271|Kit Cansat with Pico}} does have a footprint to receive an Adafruit PowerBoost 500 charger. This can also be used with a {{pl|2508|SparkFun Lipo Booster/Charger}}.

The {{pl|2271|Kit Cansat with Pico}} does have a footprint to receive an Adafruit PowerBoost 500 charger. This can also be used with a {{pl|2508|SparkFun Lipo Booster/Charger}}.

The Lipo charger must be wired to the powerboost breakout as indicated in the assembly section.

The Lipo charger must be wired to the Lipo Charger/Booster breakout as indicated in the assembly section the "[[ENG-CANSAT-PICO-ASSEMBLY|Assembling section]]".

 

We do recommend to wire the Lipo Charger/booster UNDER the base plate (to preserve access to the Pico signals on the top).

Once soldered, plug a LiPo battery and the final setup should look like the following:

* Plug the USB on the Pico to refill the LiPo.

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

* 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 LEDs are visible under the CanSat (see next section for description).

* The 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 over the radio.

* The SparkFun Lipo charger/booster do no offer LBO pin (Low Battery Output).

 

 

{{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.
