Hello again, If I may, I'd like to ask one more question for clarification. According to the most helpful reply from elcrcp there are some pins that should not be connected which are GPIO 6 - 11. A push-button with a pull-up resistor is recommended for the enable and the IO0 pin. The datasheet for t...

Good morning, Thank you very much for this eloborate reply but most of all for this helpful analysis! I've added a push-button for I0 and pressed it. And voila, the module enters programming mode. A reset button was not needed probably because the module kept resetting itself. However, I will add a ...

Some posts in this forum say that GPIO12 (MTDI) must be pulled up. The schematic of my breakout board shows that this pin is left floating. When measuring it the voltage is 0V. The pdf datasheet of this module (https://www.espressif.com/sites/default/files/documentation/esp32-wrover_datasheet_en.pdf...

Hello, I've got a brand new ESP32 Wrover IB that's soldered on a breakout board that has a 3.3V regulator and some capacitors. I use a USB-Adapter to connect it to the PC. When opening the serial monitor of the Arduino IDE I repeatedly (~ every 400ms) get this message: rst:0x10 (RTCWDT_RTC_RESET),bo...

Thank you very much for this suggestion. This module looks quite promising indeed. However it is not available on ebay as far as I can tell. Would the ESP32 cam board work as well? To access the pins needed for DAC and I2S I would ask a friend to solder some wires to the board. But would the ESP32 c...

Hello, there seems to be a large number of different ESP32 modules available. There are are web sites that show some specs for modules like here: https://www.espressif.com/en/products/modules Still, I'm not sure which one I could use for my project to stream internet radio. My requirements are as fo...

Thank you very much for the link. I hat no idea that this was available on github.

Thank you very much for this helpful insight. Looks like I need to order a regular ESP32 for my project.

Where did you find this macro? I'd like to have a look at it to better understand and learn.

Thanks again for your support!
