Taidacent Audio Generator Dual Tone Multi-frequency Decoding DTMF Decoder Encoder Keypad Board DTMF Module

DTMF V1 is a dual-tone multi-frequency decoding and encoding module. Code sending process: The ASCII code input through the serial port is converted into a dual-tone multi-frequency code after being received by the module, and then converted into an audio signal and sent out through the 3.5MM audio interface. Code receiving process: Use 3.5MM audio interface to convert the received audio signal to dual-tone multi-frequency code, and then convert it to ASCII code and send it through the serial port. The module can use audio cables to connect the input and output together, and send and receive data at the same time. The module can receive 30 data from the serial port at a time and wait for it to be sent.

Technical parameter

1 Working voltage 5VDC 2 Working current <10mA 3 Working temperature -40℃～65℃ 4 Storage temperature -40℃～65℃ 5 Size 40*30*10mm

Application

Remote device control; Dual-tone multi-frequency code decoding; Three, technical parameter table

Features

(1) Receive and send data through the serial port. (2) The audio cable can be used to connect the input and output together, and send and receive data at the same time. (3) The module can receive 30 data from the serial port at a time and wait to be sent. (4) The received data is sent out immediately through the serial port. 5. Drive mode: serial port communication format: baud rate 9600, no parity bit, 8-bit data, 1-bit stop 6. Scope of application: dual-tone signal decoding and encoding; remote control equipment. 7. Module interface: (1) Communication interface P2: 5V: Power supply positive port (5V). GND: Power ground interface. RXD: the receiving end of the module; connected to the TXD of the sending end of the microcontroller (MCU) TXD: the transmitting end of the module; connected to the receiving end RXD of the microcontroller (MCU) (2) Signal input interface J1: 3.5MM audio input interface. (3) Signal output interface J2: 3.5MM audio output interface. Module and wiring block diagram: Note: Please do not connect the circuit module directly to the serial port of the computer. You must convert the signal to a TTL level signal through (RS232 to TTL module) before it can be connected to the circuit module, otherwise the module will be damaged. (RS232 signal is negative 15 volts to positive 15 volts, TTL232 signal is 0 volts to positive 5 volts)
