    Another quick way to build a LoRaWAN is with Microelektronika's click boards. The LoRa click carries Microchip's RN2483 fully certified LoRa Sub-GHz, 433/868 MHz European R&TTE Directive Assessed Radio Modem. It is designed to use either a 3.3V or a 5V power supply. It communicates with the target microcontroller over a UART interface (TXD, RXD, CTS) with the addition of a Reset pin (RST). The US version of the LoRa Click Shield can be found here.

    To use the LoRa click board, you need a base board such as the EasyPIC V7EasyPIC V7 Development Kit or you can use the Raspberry Pi, where all you need is a Click Shield, which plugs into the Pi and the click board plugs into the Shield. Note: there are different versions of the Click Shield: Pi1 Click ShieldPi1 Click Shield, Pi2 Click Shield, and Pi3 Click Shield.
