ESP32-S3-Wroom-1-N4 module with PCB antenna

The ESP32-S3-WROOM-1-N4 module from Espressif contains the ESP32-S3 with two Xtensa LX7 cores up to 240 MHz, 512 KB SRAM, 4 MB SPI flash and an antenna on the circuit board. It provides 2.4 GHz Wi-Fi and Bluetooth 5 (LE), plus vector instructions that accelerate AI applications such as speech and face recognition. The module is soldered onto your own circuit board.

For experiments on the breadboard there is the Waveshare ESP32-S3 Development Board.
