Product details
SC9270 DTMF Decoder Module is a multi-frequency decoder. After receiving the DTMF signal, it divides it into high-frequency and low-frequency groups and sends it to the digital decoder, which determines the key value and sends it to the outside bus via four lines (Q1, Q2, Q3, and Q4) as binary from the module. It is often used in Mobile Controlled Projects or Robots.
Features
- Decode DTMF as a 4-Bit Binary
- Low Power Consumption
- LED Indication
