The STEVAL-MKI129V3 is a System-in-Package evaluation platform designed to enable users develop and test applications. Specifically, this package includes a Microcontroller Unit (MCU) for the core processing, a power management unit and a high-density Wireless Sensor Network (WSN) Sub 1 GHz for wireless communication.

The MCU is based on a Cortex®-M3 and is an 8-bit mixed signal controller. It has wide efficient peripheral sets, including DMA, CAN, EUSCIA, I2C, LCD Port, SPI, UART, and USB 2.0. The power management unit uses Linear Technology’s® LTC36xx family. It has support for multiple power sources, including USB station, battery, wall adapter, etc., and a current limited mode with overload protection.

The STEVAL-MKI129V3 has a WSN Sub 1GHz transceiver operating in the 434/868/915 MHz ISM Band with selectable power up to +15 dBm. It provides reliable short, medium range communication in the presence of interference sources and multipath fading. It is a highly scalable system with flexible bandwidth, operating at 2 different data rates: 100kbps as standard mode, and 40kbps in low power/low range mode.

In addition to the MCU, PMU and WSN, the STEVAL-MKI129V3 also contains several peripherals, including a 128kB Serial Flash, a 3-AXIS digital accelerometer, a temperature sensor, a capacitive touch sensor and a dual-mono audio codec.

The STEVAL-MKI129V3 can be used for various types of applications. It can be used for sensing, monitoring, security, and energy management applications. By using the integrated audio codec, the platform can also be used for voice communications. It has a wide range of application field — from home and building automation, smart cities and connected consumer goods to industrial and medical applications.

The working principle of STEVAL-MKI129V3 is very simple. It is based on a system-on-package design with integrated wireless capability. The Cortex-M3 MCU runs the application code and the peripheral devices work together to allow the user to interact with the platform. The power management unit manages the power sources and the WSN Sub 1GHz transceiver allows for wireless communication.

The STEVAL-MKI129V3 is a versatile evaluation platform that allows users to develop and test applications in a wide range of application fields. It uses a reliable short and medium rangecommunication and supports multiple power sources in a single package, making it an ideal platform for testing and evaluating applications.
