M77N - Mezzanine Card with 4 UARTs
The M77N is an M-Module with 4 high-performance RS232 or RS422/485 ports. It is designed as a replacement for M77 for automation, medical or in-vehicle applications in combination with MEN F12, F18 and A203.
- Four independent full-duplex asynchronous high-performance UART channels
