DNT2400C RFIO Stripline
The DNT2400C has a U.FL coaxial connector mounted near pad 42 for antenna connection (see Antenna Con-
nector discussion below). It is also possible to connect an antenna using a stripline from pad 42. It is important

UART flow control input. The host sets this line low to allow data to flow from the DNT2400 on the
RADIO_TXD pin. When the host sets this line high, the DNT2400 will stop sending data to the host.
UART transmitter output. The DNT2400 sends serial data to the host on this pin.
UART receiver input. The DNT2400 receives serial data from the host on this pin.
UART flow control output. The DNT2400 sets this line low to indicate it is ready to accept data from the host
on the RADIO_RXD input. When the DNT2400 sets this line high, the host must stop sending data.
Module’s +3.3 V regulated supply. Connect to pad 3 to support 3.3 V full scale and/or ratiometric ADC read-
ings, etc. Current drain on this output should be no greater than 5 mA.

RF ground for the DNT2400C only. Connect to the host circuit board ground plane.
Alternate RF port for the DNT2400C only. The antenna can be connected to this port with a 50 ohm stripline
or coaxial cable. Leave unconnected when using the U.FL connector.
RF ground for the DNT2400C only. Connect to the host circuit board ground plane.
