2.4G wireless module
2.4G wireless module-data, voice transmission module supports Two-way Voice Transmission or transmit data by UART that amount can be 2Kbit / S. It is smaller, lower power use, transmission longer, and stronger anti-jamming capability, so it can be widely used in various occasions which need short-range wireless communications. Industrial-grade chips guarantee the stability. According your needs, different programs are convenient for your secondary development application.
Features:
1. Operating frequency 2.4G ISM digital public band.
2. Support UART data exchange.
3. AFH Adaptive Frequency Hopping technology.
4. Shared 2.4G band with wireless LAN and Bluetooth devices at the same time.
5. Support voice intercom, the onboard microphone input and mono speaker output.
6. transmit power>=18dBm, and receive sensitivity of-100dBm.
7. Open transmission distance of 500 - 600 meters
8. Baud rate 38400bps
9. 2.54 pitch pin connector module can directly plug.
Application scope :
In short-range wireless data transmission
Data transfer, acquisition automatically
Automatically records residents' meter, such as water, gas, heat, electricity meter

IO Control | Control module enter into the data transmission or voice talkback state. When the electric which exterior provide for is higher than 3.3 V, it will enter the data transmission; When the electric which exterior provide for is hang, module enter into the speech talk back. Note: It need two module feed to high level at the same time to enter the data transmission. |
