Pins 35 and 39, 2 channels of audio out.
- wallacoloo 8y agoI expect GP meant a 3.5mm audio jack (or similar).
- teilo 8y agoI would be rather annoyed if a project board like this had a hard-wired audio jack.
- camtarn 8y agoYes, I did. I work with industrial controllers with analog outs on a daily basis, but when I wanted to build an audio board I had to do a bunch of research to find out what voltage range I needed to output, and what current I'd need to be able to source/sink. An audio jack is a hardware API contract, basically: plug a wire in here and you will get audio out of it. I don't understand why people would go so far as to be annoyed by the presence of a jack. Are you annoyed by the LED present on most project boards, if you're planning to seal up the board in an enclosure that means you'll never see it? To be fair it would add to the BOM and probably impose additional limits on the board design (large footprint, through hole pins) but I'd argue that the beginner accessibility, and the classification of this board as for audio rather than just another assorted MCU/FPGA board, would be worth it. Of course, the board designers seem to have felt otherwise.
