SPI1
If the PICtail Daughter Board is mated to the topmost SPI1 slot on the Explorer 16 or PIC32
I/O Expansion Board, the following connections will be made:
SPI1 Mating Connections
If using the PIC32 I/O Expansion Board with a PIC32 USB Starter Board (Rev B), do not
plug the PICtail Daughter Board into the SPI1 slot. The RD14/U1CTS signal is routed on the
starter board to USB power control circuitry and will cause bus contention with the
ENC624J600 chip select signal.
SPI2
If the PICtail Daughter Board is mated to the middle SPI2 slot on the Explorer 16 or PIC32
I/O Expansion Board, the following connections will be made:
SPI2 Mating Connections
Note that Explorer 16 and PIC32 I/O Exp. signal names are with respect to the Explorer 16
schematic, which assumes the use of a PIC24FJ128GA010 PIM. Various other PIMs
(e.g., PIC32MX460F512L) have a different pinout, making several of the pin names listed in
the prior two tables inaccurate. Always check the PIM or PIC32 processor board
schematics, or documentation to ensure that the signals have not been rewired.
