Build Your Own Custom Bluetooth Speaker with ESP32 & A2DP | DIY Audio Project

Let's make a custom stereo amp breakout board and use it to build a Bluetooth speaker using an ESP32 and A2DP. Thanks to PCBWay for sponsoring this video, PCBWay offer PCB Production, CNC and 3D Printing, PCB Assembly and much much more. You can find their details here: https://www.PCBWay.com/?from=atomic [1:07] Custom stereo board schematic [4:00] PCB Layout And Manufacture [7:10] Testing [8:34] A2DP Software Stack Up until now, I've been using the MAX98537 breakout board from Adafruit for most of my audio projects (see here    • ESP32 Audio Output with I2S DMA and the MA...   for a good intro to I2S and the board). I decided to create my own breakout board to support stereo output. To test it out I've created a very simple Bluetooth speaker using A2DP. This is based on the excellent work done by pschatzmann here: https://github.com/pschatzmann/ESP32-... Really very straightforward to do and a fun project! You can buy a standard mono amplifier board here - https://amzn.to/3cg88Z5 And I'm using the TinyPico board from Unexpected Maker - https://amzn.to/3vVoONp Soon as I make the updates to my design I'll publish them on PCBWay. ---- Patreon:   / atomic14   ko-fi: https://ko-fi.com/atomic14
