NuMaker-IMU-M487

This reference design is based on the NuMaker-IOT-M487 board with an IMU (inertial measurement unit) algorithm, which can be used to measure the angular velocity and acceleration of an object and obtain the attitude of the object.

This IMU algorithm is a gyro navigation system developed by UNITEC based on NuMaker-IoT-M487. It is suitable for flat navigation. Users can obtain heading angle by calling API in the IMU algorithm.

This solution had passed the test. The NuMaker-IMU-M487 is placed on the cover of the robot vacuum. The test site is kept level and greater than 6 square meters. After the robot vacuum is started for cleaning at least 30 minutes, the attitude of this solution is under an error of 10 degrees per hour. 

Nuvoton introduces the NuMaker-IoT-M487 development board for IoT applications. Embedded with the NuMicro M487 series microcontroller, NuMaker-IoT-M487 development board has built-in RJ45 Ethernet and Wi-Fi modules, which allows users to connect to cloud in a wired or wireless manner. NB-IoT, 6LoWPAN and other connectivity capabilities are provided through different wireless daughter boards to meet various application scenarios. NuMicro M487 series built-in encryption and decryption accelerator, the efficiency of encrypted network connection improves.

The NuMaker-IoT-M487 development board integrates common components and supports Arm® Mbed™ OS, built-in multi-axis sensor. It also provides compatible Arduino UNO and mikroBUS™ interfaces, which means GPIO, UART, ADC, PWM, SPI, I²C, etc. can be connected. The built-in Nuvoton NuMaker Brick I²C interface is also available. A unique simulated image sensor interface can connect to the CMOS image sensor to capture image for analysis. Combined with the NAU88L25 audio codec, the development board provides high-quality recording and playback. The external SPI Flash and microSD card socket provide additional data storage.

NuMaker-IoT-M487 provides multiple networking, interfaces, image sensing, audio recording, playback functions, and flexible extended data storage. Whether you need a sensor node or a light-weight gateway, the NuMaker-IoT-M487 is an ideal choice for IoT applications.
