10 Connectors
10.1 Breakout pads
Most I/O except the LCD pins are routed to the breakout pads at the top and bottom edge of the kit. A
2.54mm (100 mil) pitch pin header can be soldered in place on the pads for easier access.
Note
Some of the breakout pads are shared by on-board EFM peripherals. The shared pins can
be identified by looking at the Shared by column in the tables below. The schematic must
be consulted to make sure that it is OK to use a shared pin in your application.
