Additional study materials
Way of continuous check of knowledge in the course of semester
Conditions for credit:
Eagle SW complete PCB design (or other SW complete PCB design based tutor agreement). Assembled PCB has to be delivered during credit week. The PCB design documentation in form of .pdf is enclosed. The documentation comprises parts as follows: assignment, wiring diagram, PCB diagram (if double-sided, then each side separately), assembly diagram (if double-placed, then each component side separately), components list.
If student has paid for the PCB and components, the assembled PCB belongs to him. If student has developed a device for the department, he is not expected to pay anything, nevertheless the assembled PCB belongs to the department.
