HOW TO ACCOMPLISH THIS

PROJECT MANAGEMENT

PROGRESS

RISKSInput Power to Arduino Due

Risk: The Arduino Due can only have an input of 3.3 V unlike the Arduino Uno having 5 V.

Mitigation: Zener diode limiter (clamping circuit.)

Collaboration with Team Receiver

Risk: Improper co-location with Receiver Team. Mitigation: Keep in close contact with Receiver team upon design of final board.

Scheduling

Risk: Not having the code and/or board complete by deadlines. Mitigation: Sticking to Gantt chart schedule to ensure project components are completed on time.

Risk: Manufacturing company lead times being inaccurate. Mitigation: Board design submitted two weeks early in event of delay.

Test Points

Risk: Having a completed faulty board and no way to connect to certain areas to test.

Mitigation: Insert appropriate test points in design.
