Cansat ver 3.20 https://esero.no/wp-content/uploads/2016/02/The-CanSat-Book-R2.13.pdf includes a list of pins. The Norwegian page https://www.narom.no/undervisningsressurser/the-cansat-book/introduction-to-cansat/ is rather comprehensive.

The Instructables portal has a page or two on Cansat, see https://www.instructables.com/CanSat-Beginners-Guide/

Theory

This uses the Cansat shield made by Narom, Andøya Space Center. See constructing the cansat shield for more information about the shield. This intro is for version number 7, but I assume that all versions are about the same.

Materials

All material (except for the third mission) is included in the Cansat shield. We need

• Arduino
• Circuit Board (cansat shield)
• USB Cable for programming
• Antenna
• Battery connector
• Data logger (SD Card reader)
• Male pin connectors
• Temperature sensor
• Resistor for T sensor
• Header Sockets
• Dip jumpers
• GY-91 10 DOF MPU
• APC 220 Radio
• Usb Connector for radio
• And solder, soldering iron and soldering stand.

Below is some older data.

• Temperature sensor NTCLE100E3103JB0
  • Resistor 10 kOhm.
• GY-91 (BMP-280, MPU-9255)

Or

• MPX4115a
• LM35DZ
• NTC
• GPS Module
• Anything else

Building

Parachute

Vähimmäislaskeutumisnopeus: 8 m/s Enimmäislaskeutumisnopeus: 11 m/s Sallittu massa: 300–350 g ilmanvastuskertoimet: Puolipallon muotoinen: 1,5 Ristin muotoinen: 0,8 Liitovarjo: vaihtelee muodon mukaan (voidaan määrittää testeillä) Tasainen, kuusikulmainen: 0,8

Terminaalinopeudessa eli tasaisessa nopeudessa gravitaatiovoima on sama kuin laskuvarjon hidastusvoima.

$G=mg={\frac {1}{2}}C_{d}\rho Av^{2}$
