Please add a "Connection" tab to show pins and layout like your other product pages.

Hi, haley. Thank you for your kind suggestion. We have added the 'Connection' to Interface Extension Kit (AA-AA11428). Wish this could help you.

Hello. If I understand the product correctly, there are 2 input channels and 3 output channels. According to the datasheet, the ADAU1701 has 4 output channels. Is it at all possible to use the 4th output channel on this board?

Hello, geppa. Thank you for your interest in our products. Please kindly be noted that the APM3 is a 2-in, 3-out interface board. It provides RCA, 3.5mm headphone and line output ports. But they cannot be used at the same time. Wish this could help you.
