Description

The ESP32 C3 SuperMini is an loT mini development board based on the Espressif ESP32-C3 WiFi/ Bluetoot hdual-mode chip. The ESP32-C3 is a 32-bit RISC-V CPU that contains the FPU (floating point unit) for32-bit single-precision operations with powerful computing power. It has excellent F performance and supportsIEEE 802.11b /g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also has a small and delicate form factor combined with a single-sided surface mount design. It is equipped with a wealth of interfaces, with 11 digital I/ OS that can be used as PWM pins and 4 analog I/OS that can be usedas ADC pins. It supports four serial interfaces: UART, I2C and SPI. The oard also has a small reset button and a boot loader mode button. Combined with the above features, the ESP32C3SuperMini is positioned as a high-performance,lowpower,cost-effective iot mini development board for low-power iot applications and wireless wearable applications.

  1. Connect to WiFi network and Blink Builtin LED:

Copy the Following code in the IDE

#include <WiFi.h>
const char* ssid = “YOUR_WIFI NAME HERE”; //your WiFi Name
const char* password = “YOUR_WIFI PASSWORD HERE”; //your WiFi password
int ledpin=8;
void setup()
{
pinMode(ledpin,OUTPUT);
Serial.begin(115200);
delay(10);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print(“Connecting to “);
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(“.”);
}
Serial.println(“”);
Serial.println(“WiFi connected”);
Serial.println(“IP address: “);
Serial.println(WiFi.localIP());
}
void loop()
{
  digitalWrite(ledpin,HIGH);
  delay(1000);
  digitalWrite(ledpin,LOW);
  delay(1000);
}

After uploading, you will see the LED flashing on the board with a 1-second delay between each
flashing.
