This DAC and ADC module at a small price shows its versatility by proposing a complete connectivity. It offers Jack 3.5mm, coaxial, optical Toslink and an analog input on PH2.0 connector. We find the same connectivity at the output except for the Jack 3.5mm, but with a stereo RCA output. This connectivity is completed by a Bluetooth 5.0 reception and transmission capacity, so it is possible to broadcast music to the module from a smartphone or a tablet for example, but also to transmit the signal from the module to headphones or Bluetooth speakers. Practical, this function greatly limits the use of cables in a modern audio installation.
