APC340 20dBm sx1276/8無線數傳模塊

時間:2013-12-17點擊數:21961

APC340基于SX1276SX1278設計,采用SEMTECH LoRa擴頻調制技術,配合8位高速低功耗單片機,適用于對功耗、傳輸距離要求極高的應用場合,如極遠距離無線傳感器網絡,遠程工業自動化控制等,擴頻傳輸超強的抗干擾能力使之能適應于各種惡劣復雜的應用環境;SX1276覆蓋所有主要Sub-1GHz頻段,SX1278專為433MHz、470MHz頻段產品設計,APC340支持四種工作模式,各模式之間可任意切換,在周期輪詢喚醒省電模式下,使用電池供電可工作數年至數十年。

LoRa調制特殊的編解碼機制使APC340擁有極高的穩定性及適應性,超低的靈敏度及傳輸距離處于國內領先水平,模塊能夠透明傳輸任何大小的數據,而用戶無須編寫復雜的設置與傳輸程序,同時小體積寬電壓運行,較遠傳輸距離、豐富便捷的軟件編程設置功能,使之能夠應用于非常廣泛的領域。
