A.1.2 Headers
The BL2100 has an option for 0.1" IDC headers, friction-lock connectors, or bottom-
mount sockets at J1, J4, J7, J10, and J13 for physical connection to other boards or ribbon
cables. The holes on the “outside” edges of the connector locations are the holes used by
the friction-lock connectors and by the holes in the bottom-mount sockets.
Figure A-3 shows the BL2100 footprint. These values are relative to one of the mounting
holes. (Two other mounting holes are located under the RabbitCore module.)

NOTE:
The same footprint applies for the IDC header and bottom-mount socket options.
Headers J21, J22, and J23 are used to mount the optional LCD/keypad module.
