5.2.2.5:UART Interface
UART interface is implemented with single row 6 way pin header CN1007. Applied interface is
commonly used interface and allows commercially available USB/UART cable e.g. FTDI TTL-232R-
3v3 adapter cable. Pin header type is Harwin M20-9730645. Signal order in pin header is shown in
following

5.2.2.6:Audio interfaces
The evaluation module has two audio interfaces. Analog audio interface N1000 is 3,5mm standard
mono jack SJ-3523-SMT from CUI Inc providing audio in, audio out and GND. Signal order in analog
audio interface is shown in
Table 21
.
