14. Breakout Connectors (J7/J8)

Connectors, J7 and J8, provide a direct interface to select functions of the

PIC24FJ128GC010 microcontroller. Connector, J7, is a standard riser and can accept

standard 0.025” square posts. J8 is a parallel connected set of through holes. The

mapping of microcontroller pins to riser pins is listed in Ta b le 1 - 1.

Many of the microcontroller pins are multiplexed with several functions. Refer to

Appendix A. “Starter Kit Schematics” and the PIC24FJ128GC010 device data

sheet if you wish to remap the pins for a custom application.

MICROCONTROLLER FUNCTIONS

15. C2032 Battery Holder (BT1)

This allows the Starter Kit (i.e., those portions driven from the PIC24FJ128GC010

microcontroller) to be powered from a single coin cell, as opposed to USB power.

Jumper, J10, must also be configured to use the battery power feature.

16. RF Transceiver Footprint (U2)

This 14-pin area is designed to accept an optional Microchip MRF42J40A wireless

transceiver, for use with wireless application development. Note that the transceiver

requires permanent surface mounting to this area. The preprogrammed demonstration

does not support the use of the wireless transceiver.
