Where are the BS1 Schematics?

Humanoido

Looking for BS1 schematics for the following:

BS1USB
Stamp 1 Project Board

By programming, I know the power LEDs are wired differently
in these two boards, so I cannot use the universal BS1 schematic.

Thanks in advance.

Humanoido,

I'm checking with our engineer and I should have some information later today.

I found one schematic and I've attached it.· I'm still working on the other.

Thanks sincerely Dave.

Just a few questions about the BS1USB schematic.

1) The LED light is missing



2) Three versions of PDF readers cannot read the overprinted characters



3) There are some wire leads that go nowhere

....

On the schematic above, the overprinted line goes nowhere?
On the schematic at the right, pins 6 & 5 join together and then go to the right, but no connection?

Thanks for your help.

I apologize for the incomplete schematic and I will have this corrected.· The answer to your question regarding the over written line is Vdd (5V).· Pins 5 and 6 both go to Vss (ground).· The interpreter chip is missing 4 pins in the schematic.

Kind regards,

Dave

Dave,

Thank you for the Project Board schematic. This is very helpful to the new SBS supercomputer project now appearing in the Project Forum section, and working out some new programming ideas.

I look forward to seeing the revised BS1USB schematic.

I have revision B Stamp 1 Project Boards and the schematic is revision C. Where can I find a revision B schematic for the same project board?

Also looking forward to the BS1USB schematic. Thanks.

Did a clean BS1USB schematic ever surface?
I'm working on the tiny stamp supercomputer manual and it won't be complete without the schematic.
Thanks.
