Folks,

Some time ago Ossi saw my Fiat widget design and suggested there may be a market for it. I felt that the design could be bettered - for example, to bring out all the pins and to remove the ECU specific parts (and necessary software uart) - and have done so, but never found the time or the energy to do anything with it.

So, here it is. Feel free to make your own, use, abuse, whatever. I'd prefer not to see commercial versions... my feeling is that this is something which could be useful either as a beginner's experimental device, or a plug-in versatile graphical display.

Brief details:
- Overall dimensions approx 75*45
- ATMega32 or pin-compatible (8MHz max for M32)
- 3.3v on board, 6-18v input
- all surface mount 0805 passives
- ISP connector
- Optional Displaytech 64128E LCD display on rear of board
- USB (FT232R) adaptor
- All I/O connections brought out to pins on 0.1" centres
- LCD software available, including 16*6 and 8*6 fonts

Enjoy...

Neil :mrgreen:

Thanks for your nice work.
Upcoming beginners will feel good about this work.
I am also going to use this one.

Thanks. It occurs to me that I should emphasis that I have not constructed this board though I several dozen close relatives. I have no doubt it will work, but I haven't tested it...

Reviewing the board - it occurs to me that it would be wise to thicken the traces from JP4 to the diode (the positive power input), from the diode to the regulator, and from the regulator to the capacitors. That would allow more current to be taken from the AVR if required.

Also - don't forget that the board has a ground plane below and a positive (3v3) plane on the top side.
