FAQ
Does NUC505 support digital microphone? Issue Date:2018-01-15
Yes, the NUC505 Audio CODEC supports digital microphones, but only supports one set of microphone at the same time. The left and right channel data are the same. This is achieved through the digital MIC clock in PA2 (Digital MIC clock in) and PA3 (Digital MIC data out) ports to the digital audio port of internal Audio CODEC. After the digital microphone data is sent to the digital audio port of the internal Audio CODEC via PA3, the internal Audio CODEC will encode the data into the I2S format and send it to the I2S DI of the NUC505. User only needs to connect four pins in the hardware circuit, namely VCC, GND, DMIC IN (PA3) and DMIC CLK (PA2).
