Unfortunately this is for medium volume production, so modifying modules is out of question. This means we would have to roll our own module, right?

I want to clock ESP32 from it, instead of build-in 40Mhz crystal that is in the module. I need the PWM frequency to be ultra-high stability. I can't disclose what this is for.

Frequency of the high stability clock is whatever i want it to be. Other devices use 20MHz, but it can be 40Mhz or ...

My application is using ESP32-WROOM-32E-N16 module. In the new revision we need to implement a very high stability clock based on a VCTCXO oscillator. Clock signal fed into ESP32 can be either 3.3V LVCMOS or 0.6Vpp clipped sinewave.

Is there a way to feed external system clock into this module? If ...

In my product, ESP32 manages its own power. As soon as possible after startup, it asserts a POWER_HOLD line which keeps the power enabled after the user has released the power button.

There is a problem with firmware update: as soom as the ESP32 is reset into bootloader, the GPIO controlling the ...

We're considering using ESP32-S3-WROOM for a product which needs logging capability. We want to use the internal flash to reduce part count and cost, but can't find any info regarding the part number of the flash chip or at least its write endurance.

Where can I get the spec for that, or at least a ...
