Overview
4+
********
5+
6+
The Wio-WM1110 Dev Kit is based on the Wio-WM1110 Wireless Module. This module
7+
integrates a LoRa® transceiver and a multi-purpose radio front-end for geolocation.
8+
The LoRa® transceiver provides low-power network coverage, while GNSS (GPS/Beidou)
9+
and Wi-Fi scanning offer location coverage while also providing connectivity options
10+
for a variety of peripherals.
11+
12+
Hardware
13+
********
14+
15+
Wio-WM1110 Dev Kit featuring:
16+
17+
- Accelerometer, LIS3DHTR
18+
- Temperature and humidity sensor, SHT41
19+
- Two user LEDs (green and red)
20+
- Three buttons (two user and one reset)
21+
- Three Grove connectors
22+
- USB Type-C connector
23+
- GNSS antenna connector
24+
- LoRa antenna connector
25+
- NFC antenna IPEX connector
26+
- Support for solar and battery power
27+
28+

29+
30+
The Wio-WM1110 Wireless Module is embedded with Nordic Semiconductor nRF52840
31+
and Semtech LR1110. In this module the nRF52840 is intended to be used as an
32+
application processor and the LR1110 interfaces with it via SPI. Most of the
33+
interfaces and pins exposed in this board are on nRF52840.
34+
35+

37+
Nordic Semiconductor nRF52840 featuring:
38+
39+
- ARM® Cortex®-M4 32-bit processor with FPU, 64 MHz
40+
- Bluetooth®5, IEEE 802.15.4-2006, 2.4 GHz transceiver
41+
- 1 MB flash and 256 kB RAM
42+
- ARM® TrustZone® Cryptocell 310 security subsystem
43+
- Secure boot
44+

87+
88+
.. note::
89+
The Wio-WM1110 Dev Kit does not include an on-board debug probe. But it can be
90+
flashed and debugged by connecting an external SWD debugger to the SWD header.
91+
92+
Flashing
93+
========
94+
95+
You can build and flash an application in the usual way.
96+
97+
Here is an example for the :zephyr:code-sample:`blinky` application.
98+
99+
.. zephyr-app-commands::

103+
104+
Debugging
105+
=========
106+
107+
