CAN0: 2-wire, (non-FD).
CAN1: 2-wire or Single Wire (software selected), (non-FD).
CAN2: 2-wire (CAN-FD).
CAN3: 2-wire (CAN-FD).
LIN0: LIN.
LIN1: LIN or KWP.

Communication to host computer: Ethernet.

Hardware Configuration
Hardware configuration of the board is determined by customer requirements.
The hardware configuration is noted in the white "Rev" block on the top of the board.
Some hardware configurations are listed below. Other configurations are available, ask us.
A unique revision level and order number will be assigned for each unique hardware configuration requested.



PC Board Revision

PC Board Revision

The revision of the PC board is noted in copper on the bottom of the board.
It only changes when the board is redesigned.

PC Board Revision A0

1 February 2016.
Original board design.
Qty. 2 built.
Never released for production. Prototypes only.
"A1" - Remove R41. Remove R44.
"A2" - Connect NB-PD2 (NB-P2-32) to NB-UART1_RX (NB-P2-21) to monitor state of LIN0 bus. Connect NB-PD3 (NB-P2-37) to NB-UART2_RX (NB-P2-31) to monitor state of LIN1 bus.

PC Board Revision B
18 February 2016.
Changes: Corrected the 3.3 vdc converter (it was upside down); added R53 to Port F0 for ISR timing measurements; Re-sized the board to fit a Hammond RM2055M enclosure.
Qty. 2 built.
Never released for production. Pre-production only (early May 2016).
"B1" - Remove R41. Remove R44.
"B2" - Remove R41. Remove R44. Connect NB-PD2 (NB-P2-32) to NB-UART1_RX (NB-P2-21) to monitor state of LIN0 bus. Connect NB-PD3 (NB-P2-37) to NB-UART2_RX (NB-P2-31) to monitor state of LIN1 bus.
"B3" - Connect NB-PD2 (NB-P2-32) to NB-UART1_RX (NB-P2-21) to monitor state of LIN0 bus. Connect NB-PD3 (NB-P2-37) to NB-UART2_RX (NB-P2-31) to monitor state of LIN1 bus. Replace U23 with a NCP7805TG fixed three-terminal voltage regulator (very little +5v supply needed, linear regulator is more than adequate).

PC Board Revision B2
Date unknown.
Changes: Corrected the 3.3 vdc converter (again); updated footprints of both DC/DC converters.
Qty. none built.
Pre-production only (early May 2016).

PC Board Revision C
Late May 2016.
Changes: Added the solid state relays (switches) to the CAN termination network for all four CAN channels.
Qty. 100 built; now available.


Circuit Configuration - for board rev. "C" only

The "PC board revision" is noted in copper on the bottom of the board.

The "Circuit Configuration Revision" is noted in the white block on the top of the board.
