amplifier

I've been searching for a new, off-the-shelf solution to my N64 portable audio needs and have come up short. Ideally I would think we'd want an amplifier board that can do all the following: Drive external speakers (4-8 Ohm, 1-1.5W perhaps). Has built-in headphone jack. Headphone jack drops...

I think I know how to do this, but I just wanna make sure before I go ahead and start. I'm planning on wiring in a headphone/amp switching circuit to my handheld (a unit running RetroPie), which is on a Raspberry Pi B+. Using this TRS jack as an example, I'm pretty sure I need to wire Terminal...

I just received a couple prototype audio amplifier boards from JLCPCB. It's a legit miracle, I've soldered and tested them and both of them worked! So I thought I'd share them with you guys. First, I made them both to fulfill these req's: Analog audio input Analog (potentiometer/volume wheel)...

Can somebody help me (this is the amp from the bom), I feel like I wired this correctly yet I can't get it to work. I just wanted to test it so I hooked up my left and right input to a 3.5mm jack. My 5v source is coming from a 5v 2a USB source.
