Build your own Arduino compatible board ! Freeduino USB complete Kit includes all the components needed to assemble the Freeduino. All you need is a soldering iron, some solder, a multimeter and soldering skills.
The kit comes with a mini USB-B connector pre-soldered to the PCB and the Atmega 328 microcontroller.The FT232RL chip is pre-soldered, eliminating the most difficult component to solder. The rest of the components are easy to solder through-hole.
To program the Freeduino, select "Arduino Duemilanove w/ATmega328" in the Arduino IDE.
Some new features available in Arduino diecimila, implemented in this Freeduino (Arduino compatible) board:
-
AutoReset: It is possible to upload compiled sketch to the MCU without pressing the board reset button
-
USB overcurrent protection: A resettable polyfuse protects the USB port from overcurrent and shortcut situations.
-
New bootloader with 1 second delay
-
Easy to solder board
