Example Connection Arduino IDE:

To perform this example, you will need the following:

1x ESP32-C3 Super Mini Development Board || Reference ZWIXUC_ESP32-C3_super_mini

Step 1 - Download Arduino IDE

Link: Arduino IDE

Before connecting the board, start by downloading Arduino IDE 1.8.x from the link above, according to your preferences and operating system.

Step 2 - Necessary settings in Arduino IDE.

First, you will need to download a set of boards in Arduino IDE, so after opening Arduino, go to File->Preferences, and in the "Additional Boards Manager URLs" section, attach the following URL:

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

Click OK, then open "Tools"->"Board: ", and from the drop-down list, select the "Boards Manager..." button.

Search for "esp32", and the "esp32 by Espressif Systems" package should appear in the list. Click install and wait for it to finish installing.

Next, go to "Tools"->"Board"->"ESP32 Arduino" where different Arduino-compatible ESP32 boards will be displayed. Choose "ESP32C3 Dev Module" from the list.

After selecting the board, also in the tools menu, change the "USB CDC On Boot:" option to "Enabled" to allow code uploading without the need to enter the boot mode of the board.

In Arduino IDE, from the "Tools -> Port" menu, select the new port that appeared in Device Manager once the board is connected.

If you have multiple ports and are not sure which one is the ESP32-C3 Super Mini, press "RESET", disconnect the board from USB, then check the "Ports" menu in Device Manager to see which one appears.

Step 4 - Making connections and uploading test code

• Example 1: Testing the built-in LED on the board (Blink):

Copy the code below and upload it to the development board:

After uploading, the LED connected to digital pin 8 will blink with a delay of one second.

• Example 2: Scanning available WiFi networks:

Select Files->Examples->Wifi->

After uploading, open Serial Monitor and set the baud rate to the value in the code (115200).

The available WiFi networks will be scanned and displayed as shown above.
