3.8 LIN”B”
(JP: 9, 10, 38, 39, 45)
One LIN-transceiver (U4, X6) can be connected to one of the microcontroller’s UART
interfaces.
JP9
enable LIN-Transceiver
JP10
LIN Master-mode
JP38, JP39
connects UART 1 to the LIN-transceiver (U4, X6)
If the LIN interface is not used then the jumpers should be left open.
Jumper
Setting
Description
Closed
LIN-transceiver is enabled
JP9 (LIN enable)
Open
LIN-transceiver is disabled
Closed
LIN Master-mode
JP10 (LIN Master)
Open
LIN Slave-mode
Closed
SIN8 of the MCU is connected to LIN”B”
JP38 (LIN”B”RXD)
Open
SIN8 of the MCU is not connected to LIN”B”
Closed
SOT8 of the MCU is connected to LIN”B”
JP39 (LIN”B”TXD)
Open
SOT8 of the MCU is not connected to LIN”B”
Closed
Vs of LIN B is powered by the board
JP45
(VBAT_B)
Open
No voltage supply to Vs of LIN B
1-2
Connects WAKE signal to Bus power
JP42 (WAKE)
2-3
Connects WAKE signal to VCC
By default, the LIN”B”-interface is not connected to a UART.
3.9 CAN“A”
(JP: 19, 25, 26)
One high-speed CAN-transceiver can be connected to the microcontroller’s CAN interface.
JP25, JP26
connects a CAN-port to the CAN-transceiver (U7, X10).
If the CAN interface is not used then the jumpers should be left open.
JP19
selects the power supply of the CAN A transceiver (5V / 3V3)
Jumper
Setting
Description
JP25 (CAN”A”TX)
closed
TX1 of MCU is connected to CAN”A”
JP26 (CAN”A”RX)
closed
RX1 of MCU is connected to CAN”A”
1-2
CAN A VCC is set to 5V
JP19 (VCC CAN A)
2-3
CAN A VCC is set to 3V3
