Details:

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

Definition of Pin Function:  

VDD	Operating voltage,DC3.7V-5V
GND	Signal Ground
UART-TX	Transmit Data(need external voltage 3.3V)
UART-RX	Receive Data(need external voltage 3.3V)
SPK	Spreaking
MIC	Microphone
RESET	Reset the System
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.
Code Matching	Control module of code
LED Instruction	Indicating the state
