lorawan 2部分：如何使用微芯片的模块，速度的物联网设计
编者按：在这个系列的1部分，LoRaWAN 1部分：如何获得15公里和10年的电池寿命的无线物联网，我们看着LoRaWAN满足长期需求的能力，低功耗的物联网通信。在2部分，我们将展示如何开发人员可以使用一个基于微芯片技术2903架盒来实现lorawan物联网中的应用。
lorawan提供性能特点适合于物联网的需求。除了扩展经营范围和低功耗的要求，LoRaWAN提供了安全、灵活的通信选项。然而，硬件和软件需要实现一个lorawan溶液可以证明开发团队专注于物联网应用的一个主要障碍。
本文将详细阐述微芯片技术的2903 LoRa模块介绍部分1，并展示了如何使用它来实现一个远程的一些额外的硬件和软件的低功耗设计，物联网。
Quick-start kits
Microchip Technology‘s RN2903 LoRa module is a near drop-in LoRaWAN hardware soluTIon for an IoT design. Even so， it remains only the cornerstone of a complete LoRaWAN network， and developers must sTIll account for support hardware and software systems. Microchip addresses this need with a comprehensive evaluaTIon kit that provides the addiTIonal elements needed to implement LoRaWAN for the IoT.
As mentioned in Part 1， Microchip Technology’s RN2903 supports LoRaWAN-compatible communications at 915 MHz and is designed to simplify development of IoT applications. Fully certified， the Microchip module includes all of the components required to implement LoRaWAN connectivity （Figure 1）。 The module’s command processor uses the onboard LoRaWAN firmware to fully support the LoRaWAN Class A protocol. The onboard EEPROM provides storage for LoRaWAN configuration parameters， enhancing performance and increasing security by reducing data transfers between the host and module.
