BetaFPV ExpressLRS(ELRS) 奈米接收器
BetaFPV ExpressLRS(ELRS) 奈米接收器
BETAFPV Nano 接收器是基於 ExpressLRS 項目,這是一個用於 RC 應用的開源 RC 連結。 ExpressLRS 旨在在速度、延遲和範圍方面實現最佳的鏈路效能。這使得 ExpressLRS 成為最快的 RC 連結之一,同時仍提供遠端效能。
大量 ExpressLRS 商品現已上市!

了解有關 ExpressLRS 的更多信息
ExpressLRS 是用於 RC 應用的開源 RC 連結。每個人都可以找到這個項目 Github 或加入Facebook Group 中的討論。
ExpressLRS 是基於 塞姆泰克勞拉 分別用於 RX 和 TX 的 SX127x 或 SX1280 硬體。它的目標是在速度、延遲和範圍方面實現最佳的鏈路性能。在 900 MHz 時,支援最大 200 Hz 的資料包速率。目前,自訂 OpenTX 版本支援 2.4 GHz 的 500Hz。這使得 ExpressLRS 成為最快的 RC 連結之一,同時仍提供遠端效能。
越來越多的供應商開始在不同部分支援 ExpressLRS 無線電協議,例如庫存有 ELRS 的無線電發射器、內建 ELRS 接收器的無人機、適用於 JR bay 或 Nano bay 的 ELRS TX 模組。 BETAFPV團隊參與了此專案並提供了一系列ExpressLRS元件。

配置與綁定
ExpressLRS 使用 Crossfire 串行協定(又稱 CRSF 協定)在接收器和飛行控制器板之間進行通訊。因此請確保您的飛控板支援 CRSF 串列協定。接下來,我們使用帶有 Betaflight 韌體的飛控來示範如何設定 CRSF 協定。
ELRS Nano 接收器和 FC 板之間的連接如下所示。
在 Betaflight 配置器「連接埠」標籤上啟用對應的 UART(例如下面的 UART3)作為串行 Rx。
在“配置”標籤上,選擇“接收器”面板上的“基於序列的接收器”,然後選擇“CRSF”作為協定。遙測在這裡是可選的,並且由於這些傳輸插槽用於遙測,因此會降低您的棒更新率。
Nano接收器透過3次開關機即可進入綁定狀態。
插拔 Nano 接收器 3 次;
確保 LED 快速閃爍兩次,這表示接收器處於綁定模式;
確保RF TX模組或無線發射器進入綁定狀態,發出綁定脈衝;
如果接收器的燈常亮,表示已綁定。
注意:綁定一次,接收方將保存綁定資訊。重新上電,自動連線成功。
