    Great thanks, 1 question are the pads spaced 0.1" from the header, that would make it easy for putting on a breadboard?

    Nice work Mike. I have only one objection: EEPROM pin 3 should allow pull-up for using some 128KByte devices or pull down for others.Better solution available [noparse]:)[/noparse]

    Now if there was a way to take full advantage of a distributed multi-processing Spin application on these boards, it would be very useful ... for anyone who cares to understand what that means.

    Sorry to check but I mean between headers. e.g. on the eagle file above the spacing between the programming header and the 20pin header isn't a multiple of 0.1, so inserting into a breadboard would mean making sure the 2 headers are on opposite sides of the board.

    not really sure why you would want to put the eaders into a bread board. for 1 think 1 double row header like the spins studio header can't go in 1 without shorting pins out.

    you can use this:

    it is only $6 on ucontroller.com and io and power rails are labeled.

    jazzed your wish is my command. will add pull up and pull down on pin 3. if you can find a 1Mb eeprom in TSSOP package it will work.

    Why are you using TSSOP? SOIJ is more common but not as small.

    because i tried to keep to my stock parts as much as possible and i like small. Used QFP prop in this one because easier to assemble.

    Well given that, it's probably just a hack job to have the pull up/down option.
    It's hard to be everything for everyone even (or maybe especially?) when you're giving it away.
    My "giving it away days" are just about over.

    Though i could probably make money selling them I expect it will get used more and for cooler things if it is cheaper then I could sell it for.

    I want to see someone run 1000 props like this. would be cool.


    As for 1Mb i will remove the jumper. if you want you can use AT24C1024B-TH25-B

    it does not require A2 to be high like some.

    Ok i have included 3 stands. stands are grounded.

    managed to keep the 6A grid rating so all max power formulas listed are still valid.

    Jazzed mentioned wasted space.

    Current design uses female headers on all side so that by using generic male headers in the middle they can be pluged together in any orientation.

    If the design was changed to 2oz copper board($20 extra per panel) then 200mil could be shaved off 2 sides(top and right). this would allow for male pins to be used on these sides while still keeping the max grid current however if female headers were used it would weeken the mechanical strength of these headers.
