2.1 BOARD SETUP
Figure 2-1 is a photograph of the CAN/LIN/J2602 PICtail (Plus) Daughter Board. Call-
outs indicate the CAN bus, LIN bus and signal connections on the daughter board. Also
shown are two 2x15 headers that provide signals from the development board. These
headers can be probed for development, testing or monitoring of the application. For
their specific pinouts, see Section 2.3 “Auxiliary Header Pinouts”.

The daughter board obtains 9V DC input power from either the Explorer 16 Develop-
ment Board through the 120-pin signal connector (J7) or the PIC18 Development
Board through the 4-pin connector (J6) that is part of the PICtail™ daughter board con-
nector on the underside of the board. The power supply to the LIN bus transceivers is
switchable between the 9V available from the development board or an external +12V
supply. This external power supply must be connected to J1. Jumper J2 must be set to
use the required power supply.
