MT8870 DTMF Voice Encoder Decoder Module Telephone Module for Arduino  MEGA2560 NANO
 
 
 
 
Module No.:  CE005
 
 
 
Package ：(Does not include Arduino UNO/MEGA2560):
1 PCS MT8870 DTMF decoder module;
1 PCS Male to Male audio wire (3.5mm jack ) ;
 
 
 
 
 
 
 
Description: 
 
Onboard Complex Frequency Decoder IC MT8870DS 
 
Onboard 5 LED indicators for easy viewing output state 

 

DC Power Supply Voltage：5V(4.5V-5.5V)

Operating Temperature : -40-+85 °C

IO Drive : Current Maximum 10mA.

PCB Size : 25.4x25.4MM

This decoding module is for mobile and fixed telephone voice dialing decoding function
Designed specifically for ARDUINO Board.also use for other MCU(AVR PIC MSP430 STM32 ARM7/9/10/11 FPGA/CPLD)
Does not require any wiring, can be inserted directly into the UNO/MEGA2560/DUE board to use.
12 Digital outputs decode mobile and fixed telephone keys (0-9, * #).Another 4 Digital output(ABCD) can use "DTMF Dial" Software control.
