While my DE0 board is winging it thru Australia Post, I am a little confused...
1. Is there only one version of the DE0 board (from Chip) or is there a second version that Sapieha is using?
2. Can I use the BOM in Sapieha's first post? I presume from later comments that the 65R 0805 s/be 47R and the 110R 0805 s/be 82R ???
3. Just a note: 2x 100nF are 0.2" t/h (pcb seems to be 0.1") and 4x 22uF 16V 20% Tantalum are 2413 (6x3.2mm) smt.
4. Examining the circuit, there seems no reason why the 1N5819 shottky diodes could not be replaced with 1N4004.
For those Aussies getting pcbs, I will be ordering the 47R, 82R, LM1117 and tantalums, most likely tomorrow. I will get a few sets. I have 9x10K networks. I need to check if I have spares of some of the other parts available. If you want a set (free), email or PM me with your address.
Are there two versions of the DE0 emulator board? Yours looks nothing like the one I got.
There are two different DE0-Nano boards, one designed by Sapieha and one by Chip. Sapieha's has more features but has to be assembled. Chip's comes already assembled.
Chip's PCB come mounted with all components. And to You come that one.
One I made Ken send as kit --- With some components mising and some incorrect.
EDIT. To my version
1. It is 2 versions
2. That is correct.
3. Correct -- and correct on Tantalums
4. Can be used - But give litle more Voltage fail
I used on my one shottky 1N5819RL 1A

Mods made now.
And now my NANO reprogrammed and running on External voltage only. Serial and Monitor working correct
Time to test at all pins to uSD PS2 are addressed on correct positions and then run all Demo's.

Thanks David. Fantastic! That clears up my confusion.
Comments
Thanks
My version of Emulator PCB next clear to Run.
Need only cut one trace to VGA connector and solder one wire to conect to P[4]

Thanks Chip for config file.
On both my PCB and Chip's use AC adapter that don't give more that 8V measured (Not same as specified on most of them) on it else VReg will be to hot
You need PM Ken for that
Thanks David. Fantastic! That clears up my confusion.
I think one of DAC's - DAC0 in config to my version of PCB have incorrect MSB to LSB
