Free PCB Sunday: Bus Pirate PIC/AVR programming adapter

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. PCBs by Seeed Studio.

This is a PIC and AVR high-voltage programming adapter for the Bus Pirate (through-hole version). It has a 5pin PIC-ICSP header and a 6pin AVR-ISP header. It also includes a small 13volt boost-converter power supply. A 13volt VPP supply is required to program PIC 12/16/18F microcontrollers, and clear the RESET fuse in AVRs.

We’re giving away two PCBs this week. Ideally these would go to someone who can help with Bus Pirate high-voltage programming support in AVRDude, or the Bus Pirate port of USBPICPROG. Just ask for one in the comments.

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.
  • 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.

  1. I know it’s really late, but it would be great to get one of these. Is there any way to buy them?

  2. Hey, did anyone ever do a high-voltage programming mode for AVRdude+BusPirate?
    I just messed up the fuses on a bunch of ATtinys, and I’m too much of a cheapskate to just put them in the bin…

  3. do you have any of those left? I know this is a really old post, but I think it is worth giving it a try. Thanks.
