Description
BK2461 Module 128 Channel SOC 120m Long Distance 2.4G RF Wireless Serial Transparent Transceiver Module
Product Description
Using the latest 2.4G SOC technology, characterized by free development, line of sight 120 meters, send and receive without switching, transparent transmission of serial ports, providing communication protocol, can be quickly debug successful. As long as the user to understand the serial communication, without complex knowledge of wireless communications, wireless communication products can be completed. There is no packet size limit, the delay is short.
Parameter
Working frequency: 2.4Ghz
Feature
1. Half-duplex communication, excellent anti-interference performance 2. 2.4GHz ISM band. No need to apply. 3. Maximum output power: 12dBm 4. Receiving sensitivity: -95dBm 5. Transmitting working current: 40mA @ 12dBm 6. Receiving working current: 24mA 7. Sleep current: 3.5uA 8. Standard TTL level UART serial port 9. Operating frequency can be set. Multiple modules frequency division multiplexing features anti-interference performance. 10. Communication protocol conversion and RF transmitting-receiving can be switched automatically. Users don"t need to intervene, which is very easy.
