A DIY version of Bus Pirate 3.5-SOIC is now on sale in the free PCB drawer. This is our first attempt at selling something directly. The PCBs were made through Seeed Studio’s Fusion PCB service. They’re red and 100% e-tested for errors.
Unfortunately, this PCB has a minor bug, but it is easily corrected with a solder bridge between two adjacent pins on the 4066 chip. More in the forum.
PCBs are available for $3.95 each, with shipping starting at $2 ($2.50 international). That’s 2 PCBs for $5, the most-requested price point in our survey. We couldn’t get it to $5/flat because there’s a fixed cost for each order that a single PCB doesn’t cover. Payment is handled by PayPal, but you can use any credit card to checkout. We’ll have a full, public analysis of the cost for this experiment once the dust settles.
Here’s the parts in a shopping cart at Mouser, it should be everything you need to build the PCB. It is completely untested, so double check the parts before placing your order. This is a new thing for us, let us know if you use it and how it works.

Add the FT232RL to the cart
Thanks! Updated.
Curiously, the 3.3V regulator is marked as End-of-life.
Last time I checked the supply was fairly huge (1000+) so not a real problem.
The voltage regulator can be any sot23-5 3v3 part for that mather. Will look tonight for a replacement part at mouser.
try the MCP1802T-3302I/OT
1,000 parts can disappear in seconds on Mouser. I’ve had parts go into backorder where plenty of inventory was shown at the time when I clicked “Buy.” I would consider 100000+ to be safe. I’m sure a replacement is easy to find.
*Most Excellent* . Adding the mouser shopping cart was the clincher for me. Never underestimate the power of convenience!
I love the Mouser cart, it’s great to see all the parts in one place, as a starting point for removing what I have (based on my own inventory) and identifying possible substitutions.
Can you start selling part as packs
Mouser already sells the parts at prices nobody can beat. How much more do you want to pay?
I hope this works out for you Ian.
Congrats on the start! Hope this takes off for you guys.
It looks like the pay with paypal option does not add $2 shipping.
My bad, it gets there eventually (shipping when using pay pal)
too bad FT232RL is back-ordered :(
Hi dolabra, then get FT232RL from eBay at 3$ shipped
yeah, that is what I did.
