Overview
4+
********
5+
6+
RAK11160 is a WisDuo module based on the STM32WLE5 MCU with integrated LoRa
7+
transceiver. It uses an Espressif ESP8684H2 co-processor to support Bluetooth
8+
and WiFi connectivity. This module is ideal for various IoT applications such as
9+
home automation, sensor networks, building automation, and other IoT network
10+
applications.
11+
12+
Hardware
13+
********
14+
15+
The module has below hardware features:
16+
- STM32WLE5CC MCU with LPWAN single-core Cortex®-M4 at 48 MHz
17+
- 256-Kbyte Flash memory and 64-Kbyte SRAM
18+
- RF transceiver LoRa® modulations
19+
- Hardware encryption AES256-bit and a true random number generator
20+
- SMA connectors for the LORA antenna and BLE/WiFi antenna
21+
- 32-bit single core RISC-V ESP8684 MCU
22+
- 2 MB in ESP8684 MCU flash
23+
- ESP8684 MCU support 802.11b/g/n
24+
- A Bluetooth LE subsystem that supports features of Bluetooth 5 and Bluetooth Mesh

Building & Flashing
42+
*******************
43+
44+
.. zephyr:board-supported-runners::
45+
46+
Connect the board to your host computer and build and flash an application.
47+
The sample application :zephyr:code-sample:`hello_world` is used for this example.
48+
Build the Zephyr kernel and application, then flash it to the device:
49+
50+
.. zephyr-app-commands::
51+
:zephyr-app: samples/hello_world
52+
:board: rak11160
53+
:goals: build flash
54+
55+
Run a serial terminal to connect with your board. By default, ``usart1`` is
56+
accessible via the USB to TTL converter.
