Mount this jumper (JS501) to set the LIN transceiver as
Master node. Default setting in production is mounted. |
J502 |
VS_LIN |
VCC_TARGET_P3V3_P5V0 |
Mount this jumper (JS500) to power the LIN transceiver
from VCC_TARGET_P3V3_P5V0. Remove this jumper when the LIN transceiver
is powered from the LIN bus. Default setting in production is
mounted. |
J504 |
CAN device, Standby pin |
GND |
Cut this jumper to explore the standby functionality of
the CAN transceiver (ATA6561). The footprint is 0603 sized. |
