ESP32-S3-WROOM-1U-N8R8
Espressif SystemsESP32-S3-WROOM-1U-N8R8 is the external-antenna twin of the ESP32-S3-WROOM-1-N8R8, built around the ESP32-S3R8V SiP with 8 MB quad-SPI flash and 8 MB octal-SPI PSRAM in an 18 x 19.2 mm SMD module with a U.FL-class antenna connector instead of the on-board PCB antenna. Its advantage is RF flexibility: a connector lets the designer pick a high-gain or metal-enclosure-friendly antenna, recover range in shielded housings, and pass modular certification once while swapping antenna SKUs per region. Electrically and mechanically it is the same module as the N8R8, so firmware, PSRAM timing and power budgets carry over unchanged. Selection advice: the -40 to +65 C ambient rating of the R8 variants applies here too — 85 C needs PSRAM ECC and the other datasheet conditions; choose the 1U when the enclosure is metal or the range target exceeds what a PCB antenna delivers, and pick the on-board-antenna 1-series when BOM simplicity matters.
