I'm building a project that I'd like to eventually sell in small batches as a commercial product. The RPI Compute Module 4 I/O (CM4IO) has most of what I'd need, but one extra thing I need is the ability to connect a 3.5mm audio jack to use it with headphones or speakers. Adafruit has something, but I'm not too sure if it's compatible:
