Hilitand Modules Editorial Review
The 16 Channels Audio Decoder Card DTMF MT8870 Audio Decoder Phone Voice Decoding Controller is a great addition to any smart home. It can decode phone voice and control 16 channels simultaneously. This product is easy to use with 8 modes to choose from and a mini stereo jack for input audio signal. It is helpful that there is a schematic diagram available online for the MT8870 chip, which is needed to enable decoding on the ABCD pins. Keep in mind that this product is not programmable to detect a particular DTMF set, but a microcontroller like Arduino can be used to decode the output. Overall, this product is a great addition to any smart home.
