Bluetooth receiver based on an ESP, fitted on my own PCB design.
DAY 1 - 19/06/2025
- Today I started creating the PCB, more specifically the power supply:
It will be a diet with 2 voltages, one at 5v atraverse a connector to Barrell Jack, an interruption a status LED and several filter capacitors, the other at 3.3v useful for the ESP obtained at the time the use of an AMS 1117 - 3.3.
- I started thinking about that ESP 32 module to use, I think it is for one with SMA lactacco to use the external antenna.
- I decided that for the audio output I do not use the TRS or XLR connectors but of the bipolar connectors so that both types of peripheral can be connected like this:
- I evaluated the use of an DAC and I came to the conclusion that it is a necco but I still have to understand which one and how to choose it.
