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
You want a bare Bobuino board & just populate the parts you need? I could order a batch of PCBs, you build up what you need.
