描述

nRF24L01 USB 無線串口模組 串口轉 nRF24L01+ 無線通訊模組

• 支持WINDOWS 98/ME/2000/XP/Server 2003/VISTA/Server 2008/Win7/WIN8 32位/64位。
• USB無線串口傳輸模塊，支持AT 命令對系統進行配置！
• 採用穩定的 CH340T 晶片做 USB 轉串口。
• 多頻點：125頻點，滿足多點通信和調頻通信的需要。
• 模組兩個LED燈分別是電源指示燈(紅色)、nRF24L01狀態指示燈(藍色/綠色)。
• 內置看門狗防司機程序，可以在環境惡劣的工業控制場合穩定運行。
• nRF24L01 模組 插入方向如網頁下面圖片所示，插反系統不會工作，但不會燒壞無線模組
• 採用此模塊做無線串口通信可以使傳輸距離更遠(100~1100m，取決於採用的無線模塊功率)，遠遠超過藍牙串口(10m)的傳輸距離。

NRF24L01 Wireless Module Wireless Transceiver Module USB Wireless Serial Interface Transmission Booard

• USB wireless serial port data transmission module supports AT command to configure the system.
• Using a stable CH340T as a serial port for USB.
• Built-in watchdog anti-crash program can be used in harsh industrial environments.
• NRF24L01 module insertion direction should be installed correctly, when it is inserted the oppositethe, the system will not work, but will not burn the module.
• Using this module as wireless serial port can make the distance of transmission farther (100-1100m), which is depended on the wireless module, and it is farther than the transmission distance of the Bluetooth serial (10m).

Parameters and commands:
1, the number of effective bytes of a single transmission: 1-31 bytes.
The first 0 bytes of the system reserved for the transmission of each packet length statistics; For example, the serial port to send “123” (ASCII code, 3 bytes), the actual transmission of the first 0 bytes to 3, the actual receiver The number of packets received should be determined based on the number in this byte.
2, the module baud rate: 4800,9600,14400,19200,38400,57600,115200.
Covering the commonly used baud rate, (factory default baud rate of 9600)
3, NRF24L01 module transfer rate: 1Mbps, 2Mbps (factory default 1Mbps)
Transmission rate setting command: send ASCII code [AT + RATE = x] (x is 1, 2 corresponds to 1Mbps, 2Mbps transfer rate)
Such as: modify the transfer rate of 2Mbps, then the serial debugging assistant to send ASCII code [AT + RATE = 2], the system reply:

Transfer rate setting is successful!

Transmit power: 0dBm

Transmission rate: 2Mbps

Low Noise Amplifier Gain: On
4, NRF24L01 module address setting: 5-bit address, local address and receiver 0 address the same (factory default 0xFF, 0xFF, 0xFF, 0xFF, 0xFF)
Address set command: send ASCII code [AT + ADD = 0x ??, 0x ??, 0x ??, 0x ??, 0x ??] (0x ?? to set the address comma, must be a comma )
