The Rev 2 CANSAT kit is an update of the original with the USB integrated into the processor board, a terminal block for connecting a battery, and a power switch. The UART port has been updated for full UART signal access and a new conenctor has been added to provide access to two PWM ports for controlling servos. The sensor board has been updated with a new pressure sensor and two sensor expansion ports. The kit is compatible with the previous version. Lesson material has been rewritten.
