Subsystems

It is suggested that parts for the PCBs are sourced carefully using the exact model number and datasheet information. Large global suppliers such as Mouser, Farnell, RS and Digikey are normally reliable suppliers. This will avoid the risk of mismatch with PCB footprints and part specifications.
