Building an IoT project on your Raspberry Pi has never been an easy task for many developers. This is due to the messy hardware connections involved, and complicated software programming. Seeed and Microsoft have worked together to alleviate some of these challenges by introducing the Microsoft IoT Grove Kit.
The GrovePi+ cape included in the kit is fully compatible with your Raspberry Pi 3 and Raspberry Pi 2 that both run Windows 10 IoT Core. With the easy-to-use Grove system, you are now able to connect up to 15 Grove modules to your Raspberry Pi simply through the Grove interfaces on the GrovePi+.
In addition to the high performance sensors and actuators, the kit contains a 5 inch HDMI Display and a RGB LCD with a backlight. The Microsoft IoT Grove Kit is a powerful platform on which to begin your exploration on the Internet of Things.
The Dragino Lora/GPS_HAT is a expension module for LoRaWan and GPS for ues with the Raspberry Pi. This product is intended for those interested in developing LoRaWAN solutions.
The Lora/GPS HAT is based on the SX1276/SX1278 transceiver. The add on L80 GPS (Base on MTK MT3339) is designed for applications that use a GPS connected via the serial ports to the Raspberry Pi such as timing applications or general applications that require GPS information. This board can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so the HAT can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate™ technology, the Lora/GPS HAT can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions. The GPS also supports automatic antenna switching function. It can achieve the switching between internal patch antenna and external active antenna.Moreover, it keeps positioning during the switching process.
The RTC module is specifically designed for Raspberry Pi. It communicated with Raspberry Pi through I2C bus. There is a Maxim DS1307 and CR1220 button cell on the board to keep the real time for a long time after the Raspberry Pi has it’s power off. In order to offering a convenient way to debug, there are five pin has been setup which are 5v, 3.3v, Rxd,Txd on borad.
