2.4GHz -98dBm SMD,19.2x18mm RF Transceiver Modules and Modems RoHS The ESP32-WROOM-32UE-N16 is a 2.4 GHz wireless MCU module built around the ESP32 SoC. It combines a dual-core processor, integrated Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 (Classic + BLE), along with rich peripherals. The “UE” variant specifically uses a U.FL / IPEX connector for an external antenna, making it ideal for applications that require better RF performance or flexible antenna placement (e.g., enclosed products or long-range communication). The “N16” indicates 16 MB external flash memory, suitable for large firmware, OTA updates, and data-heavy applications.
