Paperduino-Uno ==============================================
Paperduino UNO is an easy and cheap way of building your own Arduino board. It is build complete with standard electronic parts and there’s no need for a printed circuit board. And you also can design your board individually.
Another advantage is that the serial to USB adapter is separated from the board. That means you can reuse it for another project, once the Paperduino UNO is programmed. And if you want to develop applications for the Arduino UNO and the modified Atmega8U2 chip (for example used as a Midi-Controller or a USB mouse) it helps a lot when you physically can change the USB to Serial adapter with the modified Atmega8U2 board.
Al boards are made with PaperPCBs. In using the Atmega368 you will have an Arduino UNO or an Arduino 2009 clone. But certainly for a really cheap version it’s possible to use the Atmega168 or the Atmega8 chip, too.
Paperduino Uno:
Paperduino 2009:
Protoduino:
1. Build the PaperPCB like described at the PaperPCB-Side.
2. Solder the board and Components.
3. Put in the chip.
4. Burn the Bootloader on the chip:
You can use an AVR Programmer, a Parallel Programmer, an Arduino or a USB to Serial adapter.
Depending on the board version you can use a standard ISP wire or you have to build your own adapter.
5. Prepare your USB to Serial adapter.
If you use the Mini-USB adapter
you have to solder an extra pin on DTR.
If you have the Atmega8U2 Breakoutboard from Sparkfun
you have to solder pins to DTR, TX, RX, VCC and Ground
! The TX and the RX connection changed !
6. Depending on the power source you have to set the jumper on the board.
7. Connect everything and voila, you have a complete Arduino.
