Auxiliary SPI Port [J7]
The Auxiliary SPI port, labeled
J7
and
SPI
on the printed circuit board, can be used for connecting to an
optional external SPI Encrypting IntelliHead with MagneSafe V5. It is a 10-pin 1.25mm pitch Molex
PicoBlade header designed to mate with Molex PicoBlade connector
51021-1000
. The dot on the printed
circuit board indicates pin 1. Pinouts are shown in
Figure 2-4 - Pinouts for mDynamo Auxiliary SPI Port J7
Depending on usage, the auxiliary SPI port can provide up to 100mA @ 3.3V to power an external SPI
device.
For details about connecting to an SPI Encrypting IntelliHead with MagneSafe V5, see the
Installation
and Operation Manual
or
Technical Reference Manual
for the module you plan to connect. Wiring
specifications for SPI heads are shown in
. Programmers should see section
for cross-references to programming tools and documentation for communicating
through the port.
