AZ3166 MXChip IoT DevKit

Overview

The AZ3166 IoT DevKit from MXChip is a development board designed for IoT (Internet of Things) projects. It’s an all-in-one board powered by an Arm Cortex-M4 processor. On-board peripherals include an OLED screen, headphone output, stereo microphone and abundant sensors like humidity & temperature, pressure, motion (accelerometer & gyroscope) and magnetometer.

More information about the board can be found at the MXChip AZ3166 website [1].

Programming and Debugging

The az3166_iotdevkit board supports the runners and associated west commands listed below.

flash debug

Flashing

Build and flash applications as usual (see Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

First, run your favorite terminal program to listen for output.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the micro:bit board can be found. For example, under Linux, /dev/ttyACM0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b az3166_iotdevkit samples/hello_world
west flash
