What flash memory chip to use

Postby don.vukovic » Thu Jan 18, 2024 7:09 pm

I would like to upgrade the flash memory chip in the ESP32-WROOM module.
What part number should I use ?
Thanks

Mine ESP32-C3-WROOM-02 module after delidding shows XMO 25qh32 SOIC-8 3V flash, so probably something like that but with more capacity.
But note that if you use flash with different voltage you'll need to burn some efuses. Also components around that flash on WROOM module are tiny and knocking something out while soldering means that your module will be unusable.
