• Windows SER driver: http://www.wch.cn/downloads/CH343SER_ZIP.html
• MacOS driver: http://www.wch.cn/downloads/CH34XSER_MAC_ZIP.html

You have to install all of these drivers as every manufacturer of this board is using different chip.

ESP32 Hardware installation:

Follow this link to install esp32 core in your ide.

After installation of core, you have to select this board as shown in this image.

Built in LED blink code does not work on this board, you have to write this code in in 38 pin esp32 to test either its built-in led is working or not.

Example Programming Code:

void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(2, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(2, HIGH);   // turn the LED on (HIGH is the voltage level)
delay(1000);                       // wait for a second
digitalWrite(2, LOW);    // turn the LED off by making the voltage LOW
delay(1000);                       // wait for a second
}
