## Description

The ideal development board for IoT projects and automation, based on the ESP32 dual core, with integrated WiFi and Bluetooth for quick network and peripheral connection. It is easily programmed from the Arduino IDE via Type-C, offers 20 digital pins and 6 analog pins for sensors and actuators, operates at 3.3V, and includes 4MB flash memory for complex applications.
Arduino compatible development board, Wemos D1 R32, ESP32 dual core processor faster than ESP8266, with integrated WiFi and Bluetooth connectivity.
The board can be programmed with the Arduino IDE via the Type C port.
This is a board that operates at 3.3V, which is why it may not be compatible with all expansion boards (shields) for UNO.

Usage:
The board may be misleading regarding power from an external source because at first glance it does not start when powered.
To start the board from an external source, it is necessary to press the Reset button.
It is recommended that, before powering from an external source, the code be first uploaded to the board via the Type-C cable (not all cables work).
To program the board, the "ESP32 Dev Module" board should be used from the boards list. If it is not present, it should be added.
Afterwards, a "Blink" code like this can be used to light the onboard LED (2).
Arduino IDE example code:
void setup() {
// put your setup code here, to run once:
pinMode(2, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(2, HIGH);
delay(1000);
digitalWrite(2, LOW);
delay(1000);
}
