@droftarts I have seen this page,but the can't find the intire model of the module ,according to the schematic Just get ESP32-S3-WROOM-1U,doesn't motion the Flash size and the RAM size

@iDavidFeng ESP32-S3-WROOM-1U-N4 is fine. The firmware binary is only 800K. We don't use PSRAM, so don't need the R# version.
