Review on 🔊 Teensy 4.0 Audio Adapter Board by David Schweigert

I followed the instructions on the manufacturer's website and made all the examples. They all worked, but when I tried the ones with the LED flashing function turned on, they crashed. by commenting out that part of the code, they worked great. I am currently developing my own code to create a noise reduction filter (DSP filter) for my amateur radio. The combined cost of the processor board and this board is much less than the cost of either of the pre-built DSL filters, and I can optimize my own code.
