The Extension Board of the Can Satellite (“CANVAS”) is an auxiliary circuit board designed to expand system functionality. As the name implies, it enables flexible integration of various sensors and specialized modules according to mission requirements.
Primary Functions of the Extension Board
Integration of User-Defined Sensors or Modules
Supports a wide range of additional components such as barometric pressure sensors, temperature/humidity sensors, radiation detectors, GPS modules, and UV sensors.
Provides physical space for custom equipment installation tailored to specific experimental goals.
The top section of the board features a PROTO area, where users can solder sensors and directly configure circuit layouts.Expansion Interface with the Main Board
Offers multiple signal lines via pin headers, including SPI, I²C, GPIO, and power connections.
Can be interfaced with the main board or sub board for integrated system control.Prototyping Area for Experimental Circuits
Equipped with a dot matrix (prototype area), allowing users to construct custom wiring or test sensor configurations directly on the board.Flexible Mission Design and Reusability
Enables mission-specific customization without altering the main board architecture.
By simply swapping the extension board, different experiments can be conducted, making it ideal for educational use and team-based CanSat competitions.
