Introduction:
The
ESP32-S3-N16R8
uses the ESP32-S3 chip, suitable for IoT application testing
prototypes and actual applications. It is equipped with two USB ports, one is a hardware USB
to serial port (CH343P WCH), and the other is the ESP32-S3 USB port.
This guide will help you quickly get started with the ESP32-S3-N16R8 and provide
detailed information about this development board.
The ESP32-S3-N16R8 is an entry-level development board with a Wi-Fi + Bluetooth® LE
module ESP32-S3-WROOM-1.
Most of the module's pins are exposed on both sides of the development board,
allowing developers to easily connect various peripherals through jumper wires or insert
the development board into a breadboard.
