I used the USB-C in parallel to "power" the PCB. Learn so far: - The former upload was successful as I can see the old program runnin...

I setup the Arduino IDE as shown in the screenshot + the build and upload was successful at least according to the screenshot. I tried to keep the code as clean as possible. void setup() { Serial.println("Hello World"); } void loop() { } however I also tried it with Serial-println in the loop. Regar...

Hi there, I have designed a custom PCB (my first one) with an ESP32, UART Bridge and some sensors. I am able to connect it, and even to upload some code (with pushing the boot button). However u don’t get any signal feedback on the serial.monitor. I tried different settings in Arduino IDE and Platfo...

thanks again for your help. That was exactly the problem! Great. Now I can proceed.

Oh okay, thank you! I will try that out. Keep you updated if this helped
