KOOBOOK 5Pcs MT8870 DTMF Voice Decoder Decoding Module Telephone/Audio Decoder Speech Module for Arduino (Color: 5PCS)

(KOOBOOK 5Pcs MT8870 DTMF Voice Decoder Decoding Module Telephone/Audio Decoder Speech Module for Arduino)

Onboard MT8870 complex frequency decoding chip,onboard voice input interface,onboard 5 LED indicator, easy to view the output status..
It is a complete DTMF receiver integrating both the bandsplit filter and digital decoder functions..
After receiving the DTMF signal, it splits the signal into a high frequency band and a low frequency band, and sends the signal to the digital decoder to decode the key value, and then the solved key value is in a binary manner with four lines (Q1, Q2, Q3, Q4) output to the external shared Bus..
When the MT8870 solves a button value and outputs it to the outside, its STD pin will rise from a low state to a high state, and then drop to a low state after a period of time.
With this feature, when the signal is detected by this pin, , the value generated by the Q1-Q4 pin is immediately read into the CPU, and then the button value of the phone is solved..
The basic chip has been the main pin leads.PCB size: 26.5 (mm) x24.5 (mm).
