CAN-FD Shield Layout
The CAN-FD Shield has a double-height DB9 connector installed by default (P3) for
CAN/CAN-FD connections.
The Shield board layout includes provision for a DB9 connector to be installed (P2) but a
standard 0.1” header (P1) is installed by default; P1 would need to be unsoldered in
order for P2 to be fitted.
Note that header P4 is provided to allow convenient access to ground.
