Install ESP32 Arduino Core (arduino-esp32) on Arduino IDE for the ESP32, ESP32-S2, ESP32-S3 and ESP32-C3

To development ESP32 Series using Arduino Framework, Arduino Core (arduino-esp32) can be installed in Arduino IDE.

The easiest way to install arduino-esp32 is using Arduino IDE. This vieo show the steps and tested on ESP32-C3-DevKitM-1.

Click on Arduino IDE MENU > File > Preferences

Enter the Stable release link or Development release link into the Additional Board Manager URLs box.

Stable release link:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Development release link:

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json

Then, open Boards Manager, Search and install esp32 by Espressif Systems.

After then boards of ESP32/S2/S3/C3 are available in boards selection.

ESP32C3_info.ino, read ESP32 info.

#include <Esp.h>

void setup() {
  delay(500);
  Serial.begin(115200);
  delay(500);
  Serial.println("\n\n================================");
  Serial.printf("Chip Model: %s\n", ESP.getChipModel());
  Serial.printf("Chip Revision: %d\n", ESP.getChipRevision());
  Serial.printf("with %d core\n", ESP.getChipCores());
  Serial.printf("Flash Chip Size : %d \n", ESP.getFlashChipSize());
  Serial.printf("Flash Chip Speed : %d \n", ESP.getFlashChipSpeed());

  esp_chip_info_t chip_info;
  esp_chip_info(&chip_info);
  Serial.printf("\nFeatures included:\n %s\n %s\n %s\n %s\n %s\n",
      (chip_info.features & CHIP_FEATURE_EMB_FLASH) ? "embedded flash" : "",
      (chip_info.features & CHIP_FEATURE_WIFI_BGN) ? "2.4GHz WiFi" : "",
      (chip_info.features & CHIP_FEATURE_BLE) ? "Bluetooth LE" : "",
      (chip_info.features & CHIP_FEATURE_BT) ? "Bluetooth Classic" : "",
      (chip_info.features & CHIP_FEATURE_IEEE802154) ? "IEEE 802.15.4" : "");
  
  Serial.println();

  Serial.println();
  Serial.println("\n- end of setup() -");

}

void loop() {
  // put your main code here, to run repeatedly:
