Re: Is it possible to use ESP32_ILI9341 to do zoom in and out?
The pinch/zoom feature does not depend on the display controller itself, but on the touch sensor applied on the surface of the display and its controller, if any. Pinch/zoom feature requires a multi-touch capacitive sensor, the type of display module you describe, seem to come with a resistive touch...

Re: Can ESP32 use multi-boot functionality by selecting operating system like Windows?
Greetings from Franco,
There are ESP32 modules with memory size up to 16MB, it is a lot of space even considering the flash partiyii for OTA. I hope I have well understood your question.

Re: Seeed XIAO ESP32C3 only runs programm when connected to PC
Could it be related to the LDO or other power management circuitry hasn't output discharge feature? Just trying to guess.

Re: Expand analog inputs
Are you designing a giant trackpad or a keyboard type of application? If keyboard, you can look at using multiple chips like this one

It can handle 18 mutual capacitance inputs.

Re: To Matter --- OR not to Matter??
Hi Keith, To my knowledge, Matter is license free, but the products must be Matter Certified to use the Matter logo. This is the same for Bluetooth, Zigbee and even Wi-Fi if the Yin-Yang Wi-Fi logo is used. Matter Certification can be much simplified by using the ESP-ZeroCode for Matter modules or E...

Re: 6x ESP32 each with Servo
You could use this LED light example and tutorial, based on Rainmaker, which will give you the firmware, the phone app and the cloud services in a very easy implementation. However, I am not familiar with how servos are controlled, if it's ON/OFF then thy job is done, otherwise it will require you t...

Re: ESP32S3 as SDIO slave at 1.8V
Due to the number of lines, an integrated circuit is a better solution, you can search for SDIO voltage translator and will get several results
MOSFET are more suitable for I2C.

Re: ESP32S3 as SDIO slave at 1.8V
According to the ESP32 datasheet, the minimum IO voltage is 2.2V, so my opinion is that to use 1.8V SDIO, you may want to add a bidirectional level shifter that can be made with a couple of N-channel MOSFETs.
