In this project, a rocket avionics control card was designed. Various sensors have been measured with an ARM microcontroller. Measurements and values are sent to the ground station by RF module. The same pcb should be used in the ground station and in the rocket. It can communicate at a distance of 10 km.
With rocket avionics backup card;
Uart Data transfer,
Powerful feed filter,
Sd card feature,
2 channel DC motor control,
You can use its features actively.
