The also arrived and this one is even worse than . At least the 98357 accurately describes itself as a DAC + Class D amp. The 5102 just says it is a DAC but is also a Class D amp.

I guess the "generate waveforms" part of this project is on hold until next week. Instead, I can work on software I need to hook up all the bits.

OK, the is working and it's if anything even more useless for my purpose than I thought.

I was looking for a and got a DAC, but with a Class D on the end of it. After I placed the order, I learned "Class D amp" means "this signal is only useful going directly to a speaker".

I'm just going to chuck these in a bin and never use them for anything again. Oooh, I'll play with the wifi/bluetooth on the board while I wait for my "programmable waveform generators" to arrive.

OK, the is working and it's if anything even more useless and stupid than I was led to believe, which is pretty useless and stupid.

I mean, it doesn't technically say right on it that it's a Class D amp, not a . So I guess this is my fault. Which I realize!

Even with the board working how I expect, the isn't. I don't think I even want to use this board, but the one I want doesn't arrive until Monday.

I wonder if I blew the board somehow while I had things hooked up wrong. It came with 3 units, I should try another one I guess.
