23-PIN ECU CONNECTOR SIGNAL
ROUTING AND WIRING HARNESS
The 23-pin ECU connector, routing
communication and external I/O
signals including:
– 2x ADC input channels;
– 2x HS PWM output channels;
– 2x PWM input capture channels;
– 3x CAN bus;
– 2x LIN bus;
– 1x 100M-base TX1 automotive
ethernet;
– +12V VBAT power supply input;
– +5V power supply output for
external devices;
The 23-pin ECU connector enables the
board to work as GP-ECU easily:
The 23-pin ECU connector matched
wiring harness with signal labels as
below photo.
