ESP32-S3-FPU

Postby surajnagulamalyala » Mon May 30, 2022 3:01 pm

Greetings of the day,

Am Looking for an Latest ESP32-S3 FPU based development board/module, Can you please differentiate from ESP32-S3-WROOM-1-N8R8 and ESP32-S3-WROOM-2-N32R8V (mentioned single precision FPU in datasheet), where as FPU not mentioned for ESP32-S3-WROOM-1-N8R8,

1) What is the use of FPU ?
2) Can ESP32-S3-WROOM-1-N8R8 Pins used/Compatible with ESP32-S3-WROOM-2-N32R8V, as I have dev kit with this module (ESP32-S3-WROOM-1-N8R8 )
3) Can you please suggest the better module from above 2 ?

Thanking you advance,
Suraj, N

Both modules use the ESP32-S3 which has a FPU in it, so both modules have the FPU. Of those two modules, the Wroom-2 has more flash (32MByte), otherwise they're the same. (Note that the Wroom-1 appears to have more GPIO, but those extra 3 GPIO pins are not usable on the N8R8 version.) Otherwise, they look compatible to me.
