Skywire® ST Micro mbed Shield
The Nucleo-F401RE is the development board for STM32 F4 series, providing an affordable, flexible way to build prototypes. For applications requiring cellular connectivity, the NimbeLink Shield plugs into the Nucleo development board and, in turn, accepts a plug-in NimbeLink Skywire® end-device certified cellular modem, providing quick cellular access. This first-in-the-industry plug-in cellular solution is easier and more compact than USB or other modem connection options, and the end-device certified Skywire embedded modem eliminates the cost and complexity of obtaining FCC and carrier certifications.
The NimbeLink shield comes with four integrated MEMS sensors for easy proof-of-concept development. Sensors include an accelerometer, a temperature sensor, an atmospheric pressure sensor, and a humidity sensor. The sensor shield also provides headers similar to those on an Arduino board. These accept any of hundreds of compatible expansion boards allowing the addition of capabilities like GPS, screens, motor controllers, and more. The NimbeLink Cellular Skywire Shield requires 5-12vdc power and accepts a variety of antennas.
The NimbeLink Cellular Skywire Shield is compatible with any of NimbeLink’s Skywire cellular modems. The Skywire line includes 4G LTE, 3G, and 2G modems including LTE-M and NB-IoT variants. These are available with bundled data plans and complete development kits.
Developers can connect to the modem in any of three different ways:
- Skywire® Socket supports 4G LTE, 3G, and 2G cellular modems
- Footprint compatible with all STM32 Nucleo Boards
- 4 sensors integrated for effective demonstration of IoT devices
- Example mbed code to upload data to Bug Labs Freeboard
