About

The ESP32-S3 is the board to reach for when a plain ESP32 runs out of steam: twice the usable GPIO (up to 45), native USB 2.0 with OTG, 14 ADC channels, and DSP/vector instructions that make it a favourite for voice assistants and AI projects. This N16R8 version carries the largest memory configuration — 16 MB flash plus 8 MB PSRAM — enough for camera work, audio processing, colour displays and MicroPython with room to spare. The board has two USB-C ports (one native USB, one via the UART bridge, so you can debug and flash at the same time), BOOT and RESET buttons, an addressable RGB LED, and a u.FL connector for an external Wi-Fi antenna. Header pins ship loose so you can mount them in the direction your project needs — or solder wires directly.
