The AC164166 extension board can be connected to any microcontroller board that contains a mikroBUS Host Header. The 14-Pin SOIC socket board contains both the I2C and the SPI interface as shown in Board Configuration. The diagram below shows a configuration using the Microchip Explorer 16/32 Development Board and the dsPIC33CK 16-bit microcontroller. Note that the Explorer 16/32 board allows for a variety of 100-pin Microchip microcontrollers to be used.
