2.4G wireless module - data, voice transmission 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. 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 can be provided for your secondary development application.
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.
