Based on the newly acquired facts, I decided that the prototype will use an ATmega644, the core of the sanguino. Here are a few technical specs:
- 4KB static RAM (that's the main reason I chose it);
- 64KB flash memory;
- 2KB EEPROM;
- completely through-hole.
Not many stores sell the sanguinos, nor the ATmega644, especially with the bootloader. I ordered mine from wulfden.org.
I already started building the board, and one of the first observations is that the distance between the two connectors (2x8-pin) on the back of the 0832 display module from Sure is not multiple of 0.1", as I expected. So my plan to use the connectors as plug-ins the "mother-board" is half ruined. I may need to use only one connector, which would confer less mechanical sturdiness, or have the "mother-board" un-attached mechanically, but connected through the short parallel cable that comes with the display. Both suck.
