The MangOh Yellow is a very capable development board packed full of features. Aimed specifically for cellular-enabled IoT applications, the board is designed to get users up and running quickly. The processor runs Legato, a variant of Linux designed specifically to integrate seamlessly with multiple wireless technologies. Furthermore, it contains all the necessary hardware to allow for multiple types of wireless connectivity.
The board sizes in at 65mm by 42mm. Available wireless connectivity options include Wi-Fi, Bluetooth 5.0 BLE, and NFC. Furthermore, a common flexible form factor (CF3) socket is available onboard for additional wireless and processing needs. For instance, many options available include a combination of 2G, 3G, and 4G cellular connectivity, GNSS positioning, and Cortex processors. Antennas are also integrated into the board design to support each of the wireless connectivity options.
Part of the design that lets developers get up and running quickly is the plethora of sensors available on board. They include an accelerometer, gyroscope, magnetometer, pressure, humidity, acoustic mic, air index quality, temperature, and light sensors. In addition, multiple LEDs, a buzzer and a touch button accompanied by 15 pin IO connector, SD card, audio connector, and IoT expansion card slot round out the additional interface options for developers.
To power up and connect to the device a USB connection is needed. This simultaneously provides power to the device as well as allows a user to make an SSH connection, send AT commands, and update the device’s firmware. In order to connect and send sensor data to the cloud, a user can set up an account with Octave, Sierra Wireless’s cloud-based IoT platform. A getting started guide is available after users register on the MangOh website. Additionally, for community help, a forum also exists for developers to share their experiences and ask questions about troubleshooting. This can be found here. Overall, the MangOh Yellow is a complex device with a rich feature set. However it offers a complete solution to getting started with IoT applications.
