ESP8266-D1 Arduino Compatible Development Board (HCDVBD0028)

Post by admin » Fri Jul 22, 2016 9:30 am


The ESP8266-D1 is a wireless 802.11 (Wifi) microcontroller development board compatible with the Arduino IDE. It turns the very popular ESP8266 wireless (WiFi) module into a fully fledged development board. The layout of this board is based on a standard Arduino hardware design with similar proportions to the Arduino Uno and Leonardo. It also includes a set of standard Arduino headers which means many existing Arduino shields can be plugged directly into the board (see note below).

The development board also includes a CH340 USB to serial interface giving it the ability to be connected and programmed directly from your computer and requiring only a common micro USB cable – no additional interface hardware or configuring is required. Once connected to the computer, and drivers have been installed, the ESP8266-D1 will appear as a standard serial COM port. The ESP8266-D1 can be programmed directly from the Arduino Integrated Development Environment (IDE) which is freely available for download from the Arduino website (

Direct Arduino IDE support for this development board can be added with just a few mouse clicks via the built-in board manager feature. Programming the ESP8266-D1 via the IDE is then as straight-forward as programming any standard Arduino development board. Many of the default Arduino commands will work including digital and analogue pin functions and many examples are included in the IDE which demonstrate how to take advantage of the ESP8266s WiFi capabilities. These examples range from simply blinking an LED to turning the ESP8266-D1 into a stand-alone web server.

To quickly get going we have provided an Arduino setup guide on our blog site here:

Please note: This board requires a USB driver to be installed. Currently supported operating systems include all 32 & 64 bit versions of Windows 7,8, & 10. Drivers can be found at the bottom of this post.

This a 3.3V development board and is not compatible with 5V hardware. Please check comparability before purchasing Arduino shields.

Example Arduino Blink Sketch:

Code: Select all

/* HCDVBD0027 Blink example - */

#include <ESP8266WiFi.h>

#define PIN 2               // Flash the LED connected to GPIO2

void setup() 
  pinMode(PIN, OUTPUT);     // Set the pin to an output

void loop() 
  digitalWrite(PIN, LOW);   // Turn the LED on  
  delay(1000);              // Wait for a second
  digitalWrite(PIN, HIGH);  // Turn the LED off
  delay(1000);              // Wait for another second
