Free PCB Sunday: Bus Pirate EEPROM board

in Free PCBs by Ian | 24 comments

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service.

This week’s free PCB is a new version of the 3 EEPROM test board for the Bus Pirate. We tried to make it cheaper by using SMD footprints that Seeed will fill with parts, and through-hole footprints for working with your own chips. This board is still hung up by the 1-wire components. Maxim might give away lots of free samples, but purchasing 1-wire parts, SMD or through-hole, is really expensive.

To get one of these PCBs, please suggest a part for a future Bus Pirate demo board in the comments. Your suggestion can be a type of part, or a specific part number if you know it. We’ll give away 2 or 4 of these this week.

The high quality picture of this week’s free PCB is thanks to our new scanner, because photographing shiny PCBs is a huge pain.

Some stuff:

  • Yes, we’ll mail it anywhere in the world!
  • Be sure to use a real e-mail in the address field so we can contact you for shipping info.
  • First come, first serve. If we can’t contact the first commenters we move down the list, so you could consider making a request even if it looks like all the PCBs are gone.
  • Limit one PCB per address per month please.
  • Like everything else on this site, PCBs are offered without warranty.

We try to stagger free PCB Sunday posts so every time zone has a chance to participate, but the best way to see the post first is to subscribe to the RSS feed.

    I would like one, please :) Thank you!

    • Zdravko says:

      Oops, forgot to put my suggestion above :)

      I have some temperature sensors chips from Texas Instruments speaking I2C protocol, a demo board for those should be handy: part numbers is TMP105.

  2. Kake says:

    Can I have one? Please. Thank you.

  3. Rohit says:

    One please?

  4. Mykeyfinn says:

    I would love one of these

  5. Mykeyfinn says:

    same issue as above, forgot my suggestion, perhaps add some capacity for testing high voltage equipment, with the Osciliscope script this might come in handy

  6. pwa says:

    yes, please.

    A ZIF socket might be handy on one of your test boards.

  7. Cristian says:

    One for me!!

  8. Greeeg says:

    I would like one of these :D

    my suggestions:
    An SPI ram footprint might be useful. (not sure how universal the pinouts are between models though.)

    I also think having a bank of MOSFET’s (mabye 3 or so) would be handy for easily connecting up higher current loads. Something like the IRF7343, as it can sink and source current.

  9. Shadyman says:

    Hmm, perhaps a series of tiny boards that sit on a downwards-facing 2×5 female header to fit over the headers, and adapt to various things, ie a 1-wire RJ12-type plug to plug in iButton readers, etc to.

  10. Rafa says:

    Can I get one?

  11. Mick M says:

    Sign me UP!!

  12. Rob T. (rct) says:

    The DS1077 dual digital programmable oscillator looks interesting. 16 khz to 133 mhz. For the lower end how about some DACs and some digital pots?

    Might open up some new possible uses for the bus pirate.

  13. Ahmed Lazreg says:

    I would like one of it’s not too late ;)

  14. Adam says:

    I’m sure it’s too late, it always is, but I’d love one if there’s still one available.

  15. Rh says:

    Well I am still trying to get the Blinkm to work properly, there is something in the way they use i2c I can’t figure out so I will suggest it. Oh I got the parts you sent.

    • Ian says:

      I got my Blinkm from the ThingM people, I was able to use it with the Bus Pirate, I posted my experience in the forum. I’ll do a larger demo later too.

  16. Dave says:

    I’d love one if you’ve got one to spare ;-)

  17. the Drake says:

    I just bought the bus pirate…this would make a nice addition if you got any spare.

  18. the Drake says:

    I plan to play with some MCP3002 or simular SPI or serial based ADC chips in a few weeks or so.

  19. Mykeyfinn says:

    Just came in today, Ingenious securing by the way :p, board is intact and tests fine, gonna start mounting components this week.

  20. Daniel says:

    Hi Ian!

    I would like to win these PCBs for tests in my home…
    Very good your website!

    Thanks,
    Daniel
