4[4]x4[4] Analog Mux
This board is designed for routing is 2 sets of 4 to 1 audio (i2s) lines (bck, fs, rd, wd) for test automation and probing. However, due to the use of analog muxes, it definitely has additional uses and can be used as an all-around analog mux with limited analog bandwidth (datasheet suggests up to 100Mhz for -3db but the board routing at 2 layers probably creates a constraint lower than this. See datasheet for details.) The routing is control is via an i2c gpio expander chip and can be interfaced to any supporting microcontroller.
