nRF21540 DB 開發組合工具包

低功耗藍牙®、藍牙®Mesh網狀網路、Thread、Zigbee及2.4 GHz專有協定範圍擴展套件開發組合工具包

nRF21540開發組合工具包(DB)包含nRF21540開發工具包(DK)和nRF21540評估工具包(EK)。

nRF21540 DK非常適於開發需要nRF21540 RF 前端模組(FEM)所提供的範圍擴展能力或鏈路預算改進的產品。nRF52840 開發工具包與我們最先進的nRF52系列開發工具包有許多相似之處。板載nRF21540 RF FEM的TX增益可以透過GPIO或SPI來調整。藍牙®5.2 nRF52840 SoC和nRF21540 RF FEM搭配是低功耗藍牙®與我們支援的Mesh網狀網路協定(即藍牙®Mesh網狀網路, Thread或Zigbee)進行多協定範圍擴展套件的完美開發工具包。雙天線埠可用於基於802.15.4協定(即Thread或Zigbee)的天線分集場景，以減少多徑衰減影響。

nRF21540 EK相容Arduino Uno Rev3擴展套件板，可與Nordic的nRF52或nRF53系列開發工具包或其他裝置一起使用。它可以透過SMA連接器連接到實驗室裝置，以監測nRF21540 RF FEM的效能。

nRF Connect SDK是nRF21540 RF FEM的軟體開發工具包，它提供對nRF21540 開發工具包的板載支援。支援低功耗藍牙®、藍牙®Mesh網狀網路、Thread和Zigbee應用的軟體開發。它整合了Zephyr RTOS、協定疊構、範例、硬體驅動程式等等。

電路板設計與原理圖可以在下載連結中找到。

包裝盒內含一個nRF21540 DK和一個nRF21540 EK。nRF21540 DK透過Micro-USB電纜(不含)連接到電腦。使用nRF21540 EK需要一根SMA電纜(不含)。
