Cansat NeXT

The CanSat is a simulated satellite — integrated within the volume and shape of a soft drink can.

The challenge for students is to fit all the major subsystems found in a satellite, such as power, sensors and a communication system, into the volume and shape of a soft drink can. The CanSat is then launched by a rocket up to an altitude of approximately one kilometre. Its mission involves carrying out a scientific experiment and a technology demonstration, achieving a safe landing, and analysing the collected data.

Getting started

Required Software

Required Hardware


  1. Download the required software (Arduino IDE):

  2. Open Boards manager from Tools>Board>Board Manager. Type in “esp32” to the search. Install the latest ESP32 Boards package provided by Arduino.

  3. Copy Cansat example scripts from to your PC.

  4. Connect CanSat to your PC with a USB cable and open the led_blink/led_blink.ino file from example scripts with Arduino IDE.

  5. From the top pane of Arduino IDE, choose “Select Board”. Your Cansat should show up as an ESP32 device.

  6. From the top pane, click “Upload” to flash the example code to your Cansat. Your Cansat board LEDs should now be blinking.
