Overview
The Texas Instruments CC2340R5 LaunchPad™ (LP_EM_CC2340R5) is a development kit for the SimpleLink™ multi-Standard CC2340R5 wireless MCU.
See the TI CC2340R5 LaunchPad Product Page_ for details.
Hardware
The CC2340R5 LaunchPad™ development kit features the CC2340R5 wireless MCU. The board is equipped with two LEDs, two push buttons and BoosterPack connectors for expansion.
The CC2340R5 wireless MCU has a 48 MHz Arm® Cortex®-M0+ SoC and an integrated 2.4 GHz transceiver supporting multiple protocols including Bluetooth® Low Energy and IEEE® 802.15.4.
See the TI CC2340R5 Product Page_ for additional details.
.. zephyr:board-supported-hw::
All I/O signals are accessible from the BoosterPack connectors. Pin function aligns with the LaunchPad standard.

Programming and Debugging
.. zephyr:board-supported-runners::
The LP_EM_CC2340R5 requires an external debug probe such as the LP-XDS110 or LP-XDS110ET.
Alternatively a J-Link could be used on the J4 header, in combination with a 3.3V power supply over the pinheader. Debugging and flashing is currently only tested using a J-Link on the J4 header.
To get a console, connect an external USB to UART converter with:
+----+-------+ | TX | DIO22 | +----+-------+ | RX | DIO20 | +----+-------+
Then you can connect to it from you PC:
.. code-block:: console
$ microcom -p <tty_device>
Replace :code:<tty_device> with the port of your USB to UART converter.
For example, :code:/dev/ttyUSB0.
Applications for the CC2340R5 LaunchPad board configuration can be built and
flashed in the usual way (see :ref:build_an_application and
:ref:application_run for more details).
Here is an example for the :zephyr:code-sample:hello_world application.
