Hi all,

I developed a PCB with the ESP32 Wrover IB:

After i ordered the first PCBs, i noticed that the data sheet changed to: Not recommended for new designs (NRND)
I searched for a new alternative, but i am not able to find one that fit.
I need minimum 8mb PSRAM.

Could you please suggest some new board. Maybe also Devkit boards that i can play around before a bit.

Best,
Daniel Ehrhardt

I'm using ESP32-WROOM-32U(16MB) in two products and just noticed these are not recommended for new design. How long will this model be available? I need the U.FL connector for an external antenna. Is ESP32-WROOM-32UE(16MB) fully compatible with the old 32U version?

Basically, ESP32-WROOM-32UE could be compatible with ESP32-WROOM-32U, but it is still suggested to read the user guide to make sure:
