The board provides an on-board microphone for audio applications. Short pin 1 and pin 2 of J13 to
select on-board microphone to be connected to the channel 7 of FPGA ADC2. The output audio
signal from on-board microphone will be pre-amplified by audio operational amplifier OPA1612,
then fed into the FPGA ADC.
Figure 3-26
shows the connection of on-board microphone and MAX
10 FPGA.

The MAX 10 NEEK comes with a standard PS/2 interface and a connector for a PS/2 keyboard or
mouse.
Figure 3-27
shows the connection of PS/2 circuit to the FPGA. Users can use the PS/2
keyboard and mouse on the MAX 10 NEEK simultaneously by a PS/2 Y-Cable, as shown in
Figure
3-28
. Instructions on how to use PS/2 mouse and/or keyboard can be found on various educational
