Uno R3 ATMega328P CH340G Development Board & USB Cable

Updated version of this popular Arduino compatible board.  Fully compatible with the Arduino IDE software and the standard boot-loader is pre-loaded, which makes uploading sketches to the board simple. 

Improvements on older version include the addition of two rows of holes for pins so that dupont cables can be used, three rows of holes for wiring and replacement of the ATMega16U2 with the CH340G.  The standard Arduino (female) connectors come pre-soldered onto this board so that it is completely ready to use, although extra (male) pins are included to enable additional connectivity should you need it.

Many thanks for looking and don't forget to check out my other items!

INSTRUCTIONS

Recent eBay policy changes prevent me from including links in this listing to external sites where you can find useful information and download tested code libraries and drivers for Windows and the Apple Mac.  However, in compliance with eBay’s new policy, I now provide full details of these links in your order confirmation email, which will be sent within 2 working days of purchase.

To operate this Development Board, you will need to download the ‘Arduino IDE’ and the ‘CH340G Microcontroller Driver’.  Apple Mac users with OSX Sierra who experience issues with this CH340G driver should use instead the ‘Alternative Mac CH340G Microcontroller Driver’ download.

EXAMPLE ARDUINO CODE

The following example Arduino code will make your Development Board on-board LED flash on and off:

// Assign Digital Pin 13.
int led = 13;
 
void setup()
{
   //Initialize the digital pin as an output.
   pinMode(led, OUTPUT);    
}
 
void loop()
{
   digitalWrite(led, HIGH);   // Turns LED on (Voltage level is set HIGH).
   delay(1000);               // Pauses for 1 second.
   digitalWrite(led, LOW);    // Turns LED off (Voltage level is set LOW).
   delay(250);               // Pauses for 0.25 seconds.
 }
