I’m a beginner at electronics and want to learn more I have been looking at tutorials on how to make an mp3 player but everyone uses premade pcb. I want to learn what I need for it and attempt to make my own pcb for the project. I’m very confused as to where and how to start. I have a LoRa 32 wifi BLE, 0.96” 128X64 OLED by HELTEC. I saw that you can make an mp3 using that but I want to make a good project and if esp32 is not the most suitable I can invest in something else. I need clarity on what to buy and where to research and study as to understand what I’m doing and how I’m doing it instead of blindly following an already made project. If anyone has any advice or tips would be very grateful.
