Looking for DTMF transceiver module

寻找 DTMF 收发器模块

I’m looking for a DTMF transceiver module compatible with Arduino. So far I have not located one that uses the MT8880 chip which as a lot of support in the Arduino community. I hope you all can point me in the right direction. 我正在寻找一款与 Arduino 兼容的 DTMF（双音多频）收发器模块。到目前为止，我还没有找到使用 MT8880 芯片的模块，该芯片在 Arduino 社区中拥有广泛的支持。希望大家能为我指明方向。
