→One-piece interfaces (J45 / J52)
It is worth remembering that some of the J45/J52 signals are reserved for internal use or shared with mezzanine board connectors. Please contact DAVE Embedded Systems' [mailto:sales@dave.eu Sales department] to get more information.
The following tables reports the interfaces' pinoutthat is the same for J45 and J52:
