CAN Header
The RZ/G1H Qseven Carrier Board supports CAN interface through RZ/G1H
CPU’s
CAN1 interface. This CAN1 interface
signals from Qseven MXM connector (pins 129
th
& 130
th
) is connected to
CAN Bus transceiver “
SN65HVD230DR
” and
to 6pin custom CAN header (J20). Mode select pin (Rs) of the CAN Bus transceiver is connected to GPIO4 (189
th
Pin) of
the Qseven MXM connector. This CAN header is physically located at the top of the board as shown below.
Number of Pins
: 6
Connector Part number : 53047-0610 from Molex
Mating Connector
: 0510210600 from Molex with crimping pins
