Cansat V2 kit in few words
The CanSat-V2-Kit is build around the Raspberry-Pi Pico plateform.
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 but can also be programmed with C++ and Arduino.
MicroPython is a very robust environment natively compiling and running python script on microcontroller. MicroPython fits a compiler, a python virtual machine and a file system to store the scripts. Thanks to MicroPython, everything learned with Python language or any MicroPython boards can be applied to the Pico.
The Cansat-V2 is built around CANSAT-V2-BASE a pre-assembled board featuring:
- Lipo battery charger
- Radio module
- 3V 600 mA voltage regulator power enable to switch off the Power.
- Plug-able microcontroler/nano-computer board (namely the MCU board)
- Connectors for I2C bus, Serial/UART, Digital I/O, Analog inputs
- Breakout of all MCU signals (offering additional I/O to your project).
- Pre-solder connector antenna (and set of antenna for testing).
Retro Compatibility
Despite obvious visual changes, the CANSAT V2 kit is backwards compatible with the previous version.
The same pins are used to control the same device.
Electronic Aspect
The kit is designed to ease the prototyping thanks to the well known connectors:
- Grove connectors : supporting 3V3 compatible SeeedStudio sensors and M5Stack sensors (all compatible 3V3).
- Qwiic/StemmaQt : which is I2C bus only. Supporting the Adafruit Industries StemmaQt sensors and SparkFun Qwiic sensors. thanks to Grove-to-Male wires.
- StemmaQT sensors are available at Adafruit Industries USA and its distributor network.
- Qwiic sensors are available at SparkFun electronic USA and its distributor network.
The "Cansat V2 Board" features a MCU board connector where to plug the MCU board.
Remark: the MCU board must be oriented with the USB connector toward the "USB" word on the silkscreen.
Presently, only the Pico MCU board is available, alternative MCU board will exists in the future.
Many of the Pin of Pico are available on Grove connectors.
All the pins of the Pico are broken out to the CANSAT-BASE.
The Pinout description and Schematics will provide lot of useful information.
About Raspberry-pi Pico
The Raspberry-Pi Pico is at the earth of this kit. One is soldered onto the Cansat MCU sub-Kit, the other is free for use to make prototyping or creating the receiving base station.
See the Cansat Pico User Guide section for more information on its integration.
See the Official Pico MicroPython starter guide for learning more about MicroPython on Pico.
Mechanical Aspect
When the kit was designed, we did foreseen the fact that the project could be assembled in many way.
The CANSAT-BASE is accompagned of several other board designed to quickly create the CanSat structure.
The following picture shows the mechanical evolution of CANSAT-LETTUCE from version 1 to version 2.
As you may notice it:
- The 3 external fixing points stays the same than version 1.
- The general diameter reduced to 60mm (instead of 64mm) leaving more room for 3D Print wall.
- The 6.4mm central hole accross all the CanSat V2 boards to build a central reinforcement column.

Cansat V2 Pico Kit content
The Cansat V2 Pico Kit is designed to be compact, evolutive, customisable, sizable (in height) and programmed in Python (thank to MicroPython).

The CanSat V2 Pico Kit is made of various products sold separately. The boards with SMD components are soldered and tested.
Some of the product like PICO-CANSAT-MCU or PICO-RFM69-433-BOOT should still have their connectors and/or MCU solder to the user.
Thankfully, when included into the Cansat V2 Pico kit the connectors are also soldered for you.
