Hi jfpeyre, Which document do you mean and which ESP-IDF version do you use? I noticed that this eFuse is named differently across releases: v5.0.8 - DISABLE_JTAG https://docs.espressif.com/projects/esp-idf/en/v5.0.8/esp32/api-reference/system/efuse.html?highlight=disable_jtag v5.4 - JTAG_DISABLE ht...

Hi barkolorious, Welcome to the forum! The short answer is yes, you can use the GPIO pins labeled as ADC2 for digital inputs and Software Serial Rx and Tx while using Wi-Fi, as long as you're not using them for ADC (Analog-to-Digital Converter) functionality. The statement you quoted is specifically...

Hi rogue1, - v5.4 (release version): This refers to a stable, final release of ESP-IDF version 5.4. It has undergone complete testing and is considered production-ready. - release/v5.4 (release branch): This refers to the development branch for version 5.4. The release branch (release/v5.4) would co...

Hi Jason,

The ESP32, including the ESP32-WROOM-32E model you're using, has a single RMT (Remote Control Transceiver) peripheral with eight RMT channels.

Hi rma-31, According to the preliminary version of the ESP32-P4 technical reference manual: Each HP core implements the RISC-V standard single-precision floating-point instruction set extension ”RV32F”. The RV32F extension also provides its own register file and various CSRs for configuration and fl...

Greetings! The issue you’re encountering with GPIO 32 and 35 not triggering edge interrupts might be related to a known limitation described in the ESP32 errata documentation regarding GPIO interrupts within the same group of GPIO pins . According to the documentation, edge interrupts cannot be used...

The 40MHz crystal is required for the ESP32 to run.

Hello Steve, The list of all certifications is at https://www.espressif.com/en/support/documents/certificates The list of all certifications for ESP32-WROOM-32E is at https://www.espressif.com/en/support/documents/certificates?keys=&field_product_value%5B%5D=ESP32-WROOM-32E I do not see any ICASA ty...

Howdy,
The brown wire on the left is connected to the blue bus on the breadboard and looks like ground. I do not see it connected to any other ground. The blue buses on the breadboard are not connected to each other.
