My system consists of 3 uppercase characters, 5 numbers i.e. EPD00501
• EPD: Refers to a Product Design PCB, EPT: Refers to a Test PCB
• 005: Refers to the PCB number
• 01: Refers to the revision of the PCB
When a PCB is modified then the revision of the PCB will change to distinguish between the old and new designs.
