Advice for a board - Bergoglio - 01-08-2025
Good morning,
I'm searching a simple ESP32 board with these connections :
- 1 LAN rj45 port
- 2 dry contacts for two different switches
- 2 GPIO pins to pilot one DFRobot DFPlayer Mini MP3 Player
- 1 GPIO pin to pilot a RGB led strip (probably a WS2812 chip)
Because I'm quite a noob in electronic, I'm not able to choose between Your products and I need Your help / advice.
Best regards

Ok, I understand that I can wiring in this way :
- on DI 1 one of the two switch
- on DI 2 the second switch
- on GPIO 1 the led strip data cable
but where can I connect the two pins of DFRobot DFPlayer Mini MP3 Player (TX / RX) ?
