Auxiliary UART Port [J8]
The Auxiliary UART port, labeled
J8
and
UART
on the printed circuit board, can be used to connect an
optional external contactless module or UART 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 2-3 - Pinouts for mDynamo Auxiliary UART Port J8
Depending on usage, the Auxiliary UART port can provide up to 400mA @ 5V to power an external
UART device.
For details about integrating an NFC contactless module or UART Encrypting IntelliHead with
MagneSafe V5, see the
Installation and Operation Manual
or
Technical Reference Manual
for the
module you plan to connect. Programmers should see section
references to programming tools and documentation for communicating through the port.
