STEM Cubesat training with Leo (8AAT). 2 month training process also addresses the lack of hands-on experience many students entering into University face due to COVID-19 High School lockdowns and remote learning for 2 years. Our attrition rate is low - so this process is working. Here, our CA2RC-SAT Team tackles Arduino Uno R3 educational computers for the first time. A great tool to prepare CA2RC members for the real Cubesat build coming soon.
