The ESP32-S3-DevKitC is an entry-level development board equipped with ESP32-S3-WROOM, a general-purpose Wi-Fi + Bluetooth® LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions.

The ESP32-S3 is a powerful, generic Wi-Fi + Bluetooth LE MCU module that has a rich set of peripherals that comes with a PCB antenna. They provide acceleration for neural network computing and signal processing workloads.

Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S3-DevKitC on a breadboard.

ESP32-S3 has a full-speed USB OTG interface, compliant with the USB 1.1 specification. The interface is used for power supply to the board, for flashing applications to the chip, for communication with the chip using USB 1.1 protocols, as well as for JTAG debugging.

Neopixel on-board is pin 48.
