Connecting more than 2 I2S mems microphones

[RedPolo]

Hello everyone,

this might be a stupid question, but I have to compare the output of 5 mems microphones and I am very confused.
I would like to use an Raspberry Pi 3B and I was able connect two I2S mems microphones onto it using the I2S GPIOs 18 until 21. Is it possible to connect more onto other Pins if I configure them correctly? Or do I need to search for other hardware?

Kind regards

You can't do 5 without more hardware. There is only a single I2S interface on the Pi and it only supports 2 channels. You need a USB to I2S interface or do what the Audio Injector Octo does and use a FPGA to multiplex it.
