The board was designed for the SEm VHDL FSM lab.
It has a beeper which can emit a Morse code signal and a microphone for receiving it.
The beeper is driven directly by a digital I/O line. The microphone's output is amplified and connected to an ADC. The amplified signal is also triggered in order to deliver a simple digital input to the FPGA.
