Hi, We noticed that our PCB design using the latest ESP32 S3 module draws significantly more current than our older PCB that used the ESP32 WROOM module. The datasheet claims that the ESP32 S3 module draws significantly less current than its predecessors but from using a bench top power supply and s...

I mistakenly remapped the original pin from GPIO0 to GPIO48 to make re-routing easier since GPIO0 on both WROOM and the S3 were on different sides of the module. I got carried away and completely neglected the fact that GPIO0 needed to be connected to the auto reset circuit instead of GPIO48... is i...

Hi, I recently designed and manufactured a custom PCB with PCBWay using the ESP32S3-1-N16 microcontroller and when I try to upload firmware via PlatformIO that worked on a previous PCB design, I get an error message saying: " Uploading .pio/build/esp32-s3-devkitc-1/firmware.bin esptool.py v4.2.1 Ser...

I also developed a custom PCB with an ESP32-S3 module and manufactured it through JLCPCB and I'm getting the same error message of "A fatal error occurred: Failed to connect to ESP32-S3: Wrong boot mode detected (0xb)! The chip needs to be in download mode." The only thing I didn't take into conside...

I'm working on a https://hackaday.io/project/165333-missions-the-sole-of-mission-st and I'm running into an issue with data transfer between a BLE scanner iOS app and the sensors attached to my ESP32. I've been trying to read pressure sensor values on ADC2 GPIOs while BLE is enabled, but all the pin...
