DFRobot Beetle ESP32 Board

This Beetle-ESP32 Microcontroller is a simplified version of FireBeetle-ESP32 and specially designed for electronic engineering fans and DIY lovers. It is equipped with 4 analog ports, 4 digital ports, UART and I2C interfaces, which would be a perfect replacement of FireBeetle-ESP32.

This microcontroller enables users to directly burn programs via the on-board USB interface. Meanwhile, Bluetooth and WIFI are integrated in the microcontroller for supporting more applications. With this Beetle-ESP32, you can easily build up your dream project.

Example Code - Blink

The default LED for Beetle Board-ESP32 is D9, input following code:




// the setup function runs once when you press reset or power the board
void setup() {
	// initialize digital pin LED_BUILTIN as an output.
	pinMode(D9, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(D9, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(D9, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
