DTMF Decoder shield for arduino
This board decodes DTMF signal either from an audio source or phone line to 4 bit binary TTL(5V) level output. It also indicates outputs with LED. Suitable for use with microcontroller applications.
Order Code : RDL/DDS/14/001/V1.0
- Decodes DTMF as 4 bit binary
- TTL level output for direct connection to microcontrollers
- Low power 5V DC operation
- LED indication of outputs
- Simple to use.
- High quality PCB FR4 Grade with FPT Certified.
