This is great! I hope it gets merged soon. I am using the 30333 labels for a project. May have to pull this PR into my local env

Praise the deity of your choice... I went through 3 other connector types before determining it was in fact a 6 pin Molex Picoblade. Bluepill to Picoblade connection/pinout could be clearer (perhaps less wire color dependent!). IDENTIFY Pin 1 on Picoblade, etc. Just my 2¢. I appreciate any ongoing clarification on this project. I've tried to help a few folks and I've needed help along the way. This is the best Hack-A-Day/GitHub project I've done!

If you have problems finding the correct Picoblade connectors, I got mine from Adafruit. Part# P4986A. As of 03/25/24 they are a whopping 95¢ each (you'll want two).

@KudzuKid This is what I used, and they worked great!

Ditto... The article needed a little refinement on a few points. Once I found the correct connector type the test of the project was a snap. I'm thinking of out-boarding the USB connector on the 'Pill to make it easier to flash different binaries for the labels. Not sure how well the plastic Dymo body will hold up with those metal screws being repetitively removed/reinstalled. Fortunately I usually just use the standard address label binary and don't often change. This hack works GREAT and I'm very appreciative of everyone's contributions.

I also wish there was a longer ribbon cable for that front-most ribbon on the main board, otherwise it wants to yank out when you open the printer (5XL in my case). Annoying. On my future improvements list to try to source that. I have an empty core I may need to scan and donate if they're still needed.

Generic labels are about 1/10 the cost of Dymo's DRM'd labels. Overall, this is a needed and fairly simple hack. Can't thank you all enough!

What's really nice about the Adafruit ones is that either set (the ones I bought or yours) are already correctly color coded for this project! :-)
