Introduction

The NL-ESP32-S3-DevKitC development board is based on Espressif's ESP32-S3-WROOM-1-N16R8 module, and is compatible with Espressif's official ESP32-S3-DevKitC-1 development board。 The biggest feature of this development board is that it uses a USB HUB chip (CH334P), directly connected to the ESP32S3 USB port (19D-, 20D+), and also connected to the USB interface of the USB to serial port chip (CH343P), and is connected to ESP32S3 UART0 (44RX, 43TX) through CH343P, so that only a TypeC interface is needed to realize download and debugging at the same time.

Pin Description

Port name	Input	output	Note information
3.3V			3.3V power output
RST			The main control chip reset pin
VIN			5V power input
GND			Power Supply
0	pulled up	√	Strapping pin, enter serial port download mode at low level
3			JTAG source
45	√	√	0:VDD_SPI is 3.3V; 1:VDD_SPI is 1.8V
46	√	√	ROM log print 1: print 0: do not print
44（RX）	√	√	U0RXD, serial download and receiver
43（TX）	√	√	U0RXD, serial port download and send port

Notes:

1. Pay attention to the level of the external device on pin 0 to prevent the motherboard from entering download mode and not working properly.

2. ST is the pin of the main control chip. It can only work normally when it is high (3.3V) ESP32S3 if the ground prevents the main control chip from starting. This means that you can restart the ESP32S3 using that pin connected to the button.

// NeoPixel Ring simple sketch (c) 2013 Shae Erisson
// Released under the GPLv3 license to match the rest of the
// Adafruit NeoPixel library

#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
 #include <avr/power.h> // Required for 16 MHz Adafruit Trinket

// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS 1 // Popular NeoPixel ring size

// When setting up the NeoPixel library, we tell it how many pixels,
// and which pin to use to send signals. Note that for older NeoPixel
// strips you might need to change the third parameter -- see the
// strandtest example for more information on possible values.

  // END of Trinket-specific code.

  pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)

  // The first NeoPixel in a strand is #0, second is 1, all the way up
  // to the count of pixels minus one.

    // pixels.Color() takes RGB values, from 0,0,0 up to 255,255,255
    // Here we're using a moderately bright green color:
    pixels.setPixelColor(i, pixels.Color(0, 150, 0));

    pixels.show();   // Send the updated pixel colors to the hardware.

    delay(DELAYVAL); // Pause before next pass through loop
