Description
RF connection to PCB antenna.
tion 4.2 )
50 RF connection through radio front end to
transceiver part of chipset. (see section 4.2 )
Ground
Serial wire clock (SWD Interface). Uses inter-
nal pull down resistor. Do not connect if not
needed.
Serial wire input/output (SWD Interface). Uses
internal pull up resistor. Do not connect if not
needed.
Reset pin. A low signal resets the module. Uses
internal pull up resistor.
Boot pin. A low signal during and short after re-
set starts the module in OTA bootloader mode.
Uses internal pull up resistor
if not needed.
Supply voltage
Operation mode pin with internal pull down re-
1
sistor during start-up. Low level or open: Nor-
mal Mode. High level: Peripheral only Mode.
Do not connect if not needed.
Indicates if module is busy with data transmis-
sion when using Peripheral only Mode (see sec-
tion 10.4.2 ). Do not connect, if not needed.
Indicates the module state (active high). Do not
connect if not needed.
Indicates the module state (active high). Do not
connect if not needed.
UART (Transmission)
UART (Reception). Uses internal pull up resis-
1
tor .
/RTS signal, if flow control is enabled. Static
low, otherwise. Do not connect if not needed.
/CTS signal, if flow control is enabled. Using
1
internal pull down , otherwise. Do not connect
if not needed.
Wake-up will allow leaving the system-off mode
or re-enabling the UART. Uses internal pull up
1
resistor . Do not connect if not needed.
Ground
(see sec-
