PSRAM Needed. Replace ESP32?

[mikesloper]

The memory on the ESP32-WROOM-32E is not enough for my application.

Can I replace it with ESP32-WROOM-32E-N16R2 or ESP32-WROOM-32E-N8R2?

I believe GPIO 16 and 17 (rs232) are a problem. I would like to keep rs232 if possible. If not possible also OK.

Also, are there plans for a new version for the A6 board with ESP32-S3 with PSRAM?

if you don't use GPIO16, then you can replace with ESP32-WROOM-32E-N16R2 or ESP32-WROOM-32E-N8R2. Because of PSRAM need use by GPIO16.
we already have the development plan, this year will design new relay controller series by ESP32-S3 N16R8 version.
