The '''Raspberry-Pi Pico''' is a powerful dual core microcontroller created by the Raspberry-Pi foundation. The Pico goes far beyond the Arduino Uno in terms of power and capabilities.
 +
 
 +
It is distributed with the MicroPython firmware and can also be programmed with C++ and Arduino.

 +
MicroPython is a very robust environment natively compiling and running python script. MicroPython fits a compiler, a python virtual machine and a file system to store the script. Thanks to MicroPython, everything learned with Python language or MicroPython boards can be applied to the Pico.
 +
 
 +
The kit is designed to ease the prototyping phase, it can be open flat on the desk to ease access to every logic signals and components/boards added to the initial setup.
 +
 +

 +
 
 +
The "Cansat Pico Board" feature the Raspberry-Pi Pico and already embeeds useful and smart features to ease the prototyping and testing phase for your Cansat project.
 +
 
 +
When the kit was designed, we did forseen the fact that the project could either be:
 +
* placed between the boards (inside).
 +
* placed ouside of the boards and use a shorter ribbon (boards are enclosed right in the middle of the project).
 +
 
 +
We did also features a Qwiic/StemmaQt connector available underside. This very compact connector do features power and I2C bus. It can be used to quickly and safely connects toons of I2C capable sensors boards.
 +
* [https://www.adafruit.com/category/1005 StemmaQT sensors] are available at [https://www.adafruit.com Adafruit Industries USA] and its distributor network.
 +

 +
 
 +
Just flip over the "Cansat Pico Board" to discover additional features available underside the Pico.
 +
 
 +
As we can propotype under the board, it is also very important to have the board fully labelled this side.
 +
 
 +
[[fichier:ENG-CANSAT-PICO-CONTENT-13.jpg|640px]]
 +
 
 +
As the Raspberry-Pi Pico doesn't features Lipo battery circuitery, we do added a special connector to plug an [https://www.adafruit.com/product/1944 Adafruit PowerBoost 500 charger] on the board.
 +
 
 +
Just connect the Pico to you computer (or power it with a wall adapter) and the Lipo will auto-magically starts to charge-up.
 +
 
 +
Unplug your pico from computer and the PowerBoost charger will take over. The Lipo will discharge to power your project.
 +
 
 +
Thanks to the PowerBoost, your cansat projet do also have a 5V power rail (500 mA max).
 +
 
 +
Needs to spare energy? no problem, the "Power Off" pin is available near of the board boundary. Once the PWR_OFF tied to the ground, the PowerBoost is disabled (as Pico and the project).

You can develop your project:
 +
* '''either''' in the inner space between the bottom and the top boards.
 +
* '''either''' using smaller spacers to develop your project in the inner space {{underline|and}} also the outer space.
 +
 
 +
Outer space can also be used thanks to the through holes PCBs and the labelling the both sides of the PCBs.
 +
 
 +
=== Pico Boards ===
 +
 
 +
The Raspberry-Pi Pico is at the earth of this kit. One is soldered onto the Cansat Kit, the other is free for use to make prototyping or creating the receiving base station.
