ISM頻段，內置頻率合成器、功率放大器、晶體振盪器、調製器等等功能芯片，並融合了增強型ShockBurst技術，其中輸出功率和通信頻道可通過程序進行配置。nRF24L01的特點是功耗低，在以-6 dBm的功率發射時，工作電流只有115mA，在接收時，工作電流只有45mA。\nNRF24L01+配有PA(Power Amplifier) 和LNA (Low-Noise Amplifier) 芯片，和2.4GHz 2.2dBi天線，使得有效通信距離大大擴展到800米，更可用於點對點傳輸或組成星形網絡。", "specs": { "voltage_v": { "typ": 1.9 }, "logic_level_v": 3.3, "interface": [ "spi" ], "connectivity": [ "wifi" ], "chip": [ "nRF24L01+" ],

"供電電壓為1.9V至3.6V，典型3.3V。切勿直接使用5V供電，否則會燒毀模組。與5V單片機（如Arduino Uno）連接時，所有信號線（CE、CSN、SCK、MOSI、MISO、IRQ）必須經過電平轉換，例如使用電平轉換模組或分壓電阻。PA+LNA版本發射時電流較大（約115mA），建議在VCC和GND之間並聯10uF至100uF的電解電容以穩定電源，避免因供電不足導致通信失敗。天線應垂直安裝，並遠離金屬物體和地面，以獲得最佳通信距離。市面上有很多副廠模組，晶片可能為仿製品，性能差異較大。部分模組的引腳順序可能不同，使用前請以實物絲印為準。"
