LIN Configuration

The EVB is fitted with an NXP MC33661F LIN transceiver (U50) and two different style connectors: A
standard LIN Molex connector (J14) at the edge of the board and a standard 0.1" connector (P3).
The pin-out of the Molex connector J4 is shown in Figure 8.
For flexibility, the LIN transceiver is also connected to a standard 0.1" connector (P3) at the top side of
the PCB as shown in Figure 9. For ease of use, the 12V EVB supply is fed to pin1 of P3 and the LIN
transceiver power input to pin2. This allows the LIN transceiver to be powered directly from the EVB
supply by simply linking pins 1 and 2 of connector P3 using a 0.1" jumper shunt.
By default the LIN interface is not enabled. To enable the LIN interface the jumpers detailed in Table 5
need to be placed.
