To ensure that your order reaches you in the fastest time possible and in good condition, we ship our goods only through DELHIVERY, DTDC, and SPEEDPOST.ĭepending upon the weight and destination, the shop will automatically calculate shipping charges for the order (refer to Shipping Charges for more details). 12 Digital outputs decode mobile and fixed telephone keys (0-9, * #).Another 4 Digital output(ABCD) can use "DTMF Dial" Software control.ĭTMF Decoder module with chip for Arduino Does not require external circuits, can be inserted directly into the UNO/MEGA2560/DUE board to use.Can also be used for other MCUs(AVR PIC MSP430 STM32 ARM7/9/10/11 FPGA/CPLD) Designed specifically for ARDUINO Board.This decoding module is for mobile and fixed telephone voice dialing decoding function.Onboard 5 x LED indicators for easy viewing output state.Can be used to build mobile controlled robots, home automation projects, IVR style applications, etc FEATURES This module is suitable for modem interfaces, mobile radios and other DTMF related applications. You may connect a phone to the module and the module will output the key(0-9, *, #, A, B, C or D)pressed on the audio source. The DTMF Signal in the audio source is decoded and the digital outputs on the module, indicate the key pressed. The module offers a 3.5mm audio connector to connect an audio source. Suitable for use with microcontroller applications.This is a MT8870 DTMF Decoder Module. Decodes DTMF audio signal to 4 bit binary TTL level output with LED indication.
