A.1.1 Headers
The RCM2200 uses headers at J4 and J5 for physical connection to other boards. J4 and J5
are 2 × 13 SMT headers with a 2 mm pin spacing. J1, the programming port, is a 2 × 5
header with a 2 mm pin spacing.
Figure A-3 shows the layout of another board for the RCM2200 to be plugged into. These
values are relative to the header connectors.
A.1.2 Physical Mounting
A 9/32” (7 mm) standoff with a 4-40 screw is recommended to attach the RCM2200 to a
user board at the hole position shown in Figure A-3. Either use plastic hardware, or use
insulating washers to keep any metal hardware from shorting out signals on the RCM2200.
