The ESP32-S3-WROOM-1U-N16R8 is a powerful wireless MCU module designed for advanced IoT, AIoT, embedded, automation, and connected-device applications. It features a dual-core Xtensa LX7 processor running up to 240 MHz, integrated 2.4 GHz Wi-Fi and Bluetooth Low Energy connectivity, 16 MB Flash memory, and 8 MB PSRAM.
The 1U variant uses an external antenna connector instead of an integrated PCB antenna, making it suitable for applications requiring flexible antenna placement or improved RF performance.
