One of the sponsors of the CTE Mission CubeSat challenge is XinaBox.cc. They developed a unique system of arduino based components, sensors and radios for the STEM/STEAM market. The components “snap” together forming a rigid stable platform for experimentation. Their system is much faster to assemble than traditional breadboarding or even 4-wire systems such as Adafruits’ STEMMA or Sparkfun’s Qwiic. This allows components to be shared among multiple classes, since students can quickly break down and setup their projects.
In addition to Arduinos, their “bridges” allow use of other processors such as Raspberry Pis and micro::bits with their system.
