I really like the flexibility of HQ’s programming key. There’s no reason you couldn’t adapt nearly any PCB design to use it (or some variation of it). I picked up 6ea from oshpark and can’t wait to try my hand at designing my own driver boards with integrated programming ports.
Thanks for open sourcing the design. I’ll probably try using kicad, so I’ll see if I can release some definitions for the footprint.
Are you already a user of KiCAD? I’d like to learn it, but the learning curve is steep for me. There is an Eagle tutorial around here from years ago, which helped a lot of us get started in PCB design. If you know how to use KiCAD, it would be helpful to at least some of us if you could help out with a quick-start tutorial of sorts. :innocent:
Never used kicad, I’ve used eagle a bit in the past. This is mainly a good excuse and project for me to get back into embedded electronics. I’ve been meaning to learn kicad for a while (not a huge fan of eagle since auto CAD bought them). I’ll definitely try to document my descent into the abyss!
Alternatively if there is another inexpensive part that allows me to go from the key to the USB ASP let me know. I have small gauge wires and extra jumper wires but nothing else.
Thanks I bet I could snip the ones I got shorter if the pads line up right. I got extras. If not I guess the wires may help with the flexing.
On a related note, DigiKey has outdone themselves and they are now competing with Arrow packaging (RIP Free Shipping).
FW3A for scale.
Why such a big box you ask? To protect the 4 feet of heatshrink tube of course. Other items included a few LEDs, resistors, and those jumpers. :person_facepalming:
Yea Mouser has been doing that too for years… I think they are concerned you will call it ‘damaged’ if it arrives kinked.
The “fix” is to include a note on the order that says “Please fold the heat-shrink to reduce shipping costs.” That has been working for me.
Check these out. I actually had this exact idea for edge mounting the connector a month ago and even ordered parts to build one. Now a more intense Google search shows the exact idea already exists.
