Retired: This product has been replaced by a newer version USB Boarduino v2.0. This page is for your reference only.

If you've ever struggled to use a solderless breadboard with an Arduino, you understand how frustrating it can be!
This clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferrable! The kit includes all parts necessary, the assembly is straightforward and well documented.
This version of the Boarduino does not have a DC jack. That means you can't use a 9V adapter or battery holder with it (unless you build a 5V power supply). However it does have USB built in and you can power your project with USB or by using a Mintyboost kit (which takes 2 AA batteries)


  • Designed to plug into a breadboard for easy prototyping
  • Petite size, only 3" x 0.8" (75mm x 20mm)
  • All 'standard' pins are brought out - Digital 0 thru 13, Analog 0 thru 5, ARef, 5V, Ground, Vin and Reset
  • Chip comes preprogrammed with my "no-wait" Arduino bootloader (Read more here).
  • All through-hole parts are easy to solder (SMT parts are presoldered and tested)
  • 2 LEDs, green power and red "pin 13" just like the Arduino!
  • All through-hole parts are easy to solder
  • Reset button
  • Atmega328 chip has twice as much storage, runs at 16.00 MHz, just like the latest Arduino. Upload baud rate is 57600, use Arduino IDE v13+ (note that the product photo above hasn't been updated)
  • 6-pin standard ICSP header
  • Standard USB jack (just like the original Arduino)
  • 500mA fuse protects your computer's USB port from overcurrent
  • 6-pin header at the end for a USB-TTL cable
  • Auto-reset capability (can be easily disabled by removing or not installing a capacitor)
