adilinden: Are there any plain basic 1284 boards with UNO foot print? The Bobuino is cool but way more features then I need. Essentially need UNO foot print, more RAM then 328 offers and shield compatibility. Be connecting Ethernet shield and a GSM shield. Much prefer on board USB over external FTDI.
The only board I know of with the Uno footprint is this one, http://www.thaieasyelec.net/index.php/Arduino/ATmega32-Dev-Board-Arduino-Diecimila-Compatible-DIP-28-DIP-40-/p_133.html, but it's out of stock and the corresponding Thai page seems to indicate it has been "retired", http://www.thaieasyelec.com/Development-Board/Arduino/Dev-Board/Arduino-Diecimila-Compatible-DIP-28-DIP-40-ATmega32.html.
If you want something that's fully shield compatible (including the location of the ISP header - essential for using the Ethernet shield) then I think my Calunium board is the only other option. The footprint is similar to the Mega2560 footprint (same length, a bit wider). All the files and software are available on Github under a CC license. I had 10 PCBs made by Iteadsutdio for $25, and delivery was just $5. You only need to populate a few and the cost each is about the same as the Uno. You will need an FTDI cable.
