▪ UART interface driven by USB FTDI chip – In normal operation, the M.2 UART interface is driven by the
FTDI FT232R USB to UART converter.
3.4.3 UART Interface Driven by External Source
▪ UART interface driven by external UART source – The M.2 module UART interface (TX, RX, CTS, RTS) is
presented at a 2.54 mm (0.1 in.) pitch headers (J15, J16, J17 and J18). To allow the M.2 UART interface to
be driven from the breakout header connector (J15, J16, J17 and J18):
– Development board must be powered from DC jack (CON5) and switch SW1 is in position DC JACK 5V.

3.5 32.768 KHz Oscillator
The development kit is fitted with a (U1) 32.768 KHz oscillator which provides sleep clock to M.2 module.
Fit a jumper on J1 to disable the sleep clock, if needed.
