Buy Freeduino



Freeduino.org releases files and provides a name... other people do the rest. Some people have made new products with the Freeduino PCB files, while others have adopted the Freeduino name in true open-source spirit! We list each of them here with a link to its appropriate maker/vendor, in no particular order.

Didd you make a Freeduino board with the name "Freeduino" printed on it? Send us the detials and we'll post it here for free!

 

Freeduino USB: the original!

!

NKC Electronics has a Diecimila-compatible USB Freeduino that is available as a kit, with the USB chip pre-soldered.

 

Freeduino SB 2.2

Wow! This is the Freeduino SB 2.2, designed and built by the fine folks at Solarbotics. The "SB" 2.2 is 100% compatible with the Arduino Diecimilatm, and adds some extra perks:

  • choose between a type "A" or type "B" USB socket
  • preinstalled 16MHz crystal
  • FTDI "Bit-Bang" interface pins
  • battery-friendly power routing
  • space to add an optional potentiometer for ARef (analog reference)
  • has a power swtich
  • the RX/TX leds are near the USB jack, meaning you can see them with a shield mounted
    four mounting holes
  • attractively priced at $26!

The Freeduino SB 2.2 is sold as a "semi kit", with the surface-mount components already professionally soldered. You just need to solder theincluded through-hole parts like the socket, header pins and jacks. Check it out over at Solarbotics / HVWTech...

 

Freeduino Epic

Wow! This is the Freeduino Epic, a new Freeduino by DH-Global. In their own words, "The Freeduino Epic is an Arduino Mega compatible clone with minor differences. It has the same specs, i.e. an ATmega1280 microcontroller with 54 digital I/O's, 16 analog inputs, 4 UART's, power jack, reset button, and an ICSP header. The main difference is it does not have a USB port, but a serial header to be used with an FTDI USB to serial cable. Not putting USB on the board lowers the cost of the board benefitting the buyer. It also does not come with headers for the I/O. "

JK Devices Freeduino 5V/3.3V Hybrid

Another Freeduino is born, this time from JK Devices. The JKD Freeduino Hybrid is dual-voltage, dual regulator Freeduino Board that is Arduino Shield and Duemilanove compatible. Special features include on-board level translators for 5V/3.3V, an additional header aligned to 0.1" grid for breadboard compatibility that allows you to create your own shields without modifying or bending pins, and all the usual Freeeduino/Arduino fixings. Even better, it is available as kit, so you can solder up a storm, just as every good Freeduino builder was meant to do!
