Thank you. I also was assuming these should be connected to GND, but the footprint I got had all those vias connected to nothing, causing KiCad to give lots of DRC errors.

I have quad PSRAM enabled, but these GPIOs are reserved at startup regardless of the PSRAM selection, and based on the definitions inside soc_caps.h file for ESP32-S3 chips.

Hi! I have a WT32-SC01 Plus module which according to the datasheet has an ESP32-S3-N16R2 on it. The board uses GPIO number 35, 36, and 37 for I2S. When I use a simple Arduino sketch, I can hear the sound from the speaker I connect to it. The problem is when I want to do the same thing with ESP-IDF ...

Hello. I have seen in multiple footprints of ESP32-S3-WROOM-1U that there are vias around the central ground plane like in this image https://ibb.co/vLcg8hp ( https://ibb.co/vLcg8hp ) What is the use of this? And can I just remove them, or at least put them on the ground pins? I'm getting A LOT OF r...

Hi all! I've seen in the documentation of ESP32-S3-WROOM-1 that IO47 and IO48 pins on modules with PSRAM are set to 1.8V logic. Is it possible to do the same in modules without PSRAM, and then use these pins for UART connection to a GSM module that works at 1.8V?

I'm trying to use the new I2C driver (5.3.1). The problem is when I add a callback function, I can use i2c_master_transmit_receive fine, but I see a warning in the logs that says async I2C is experimental (well, this is the driver that deprecated the normal i2c.h, and it's still experimental!!!). Th...

Oh that's correct. I totally missed that one

Hi! First of all, I think this new I2C driver really needs extra API for writing to an addressable register because copying the whole buffer every time you want to write something just doesn't make sense! And my question is, what about reading from a register? You need a repeated start after sending...
