All transparent changes to a user but significant enough to trigger a new SKU.</p>

One says TX0 is GPIO1, the other says TX0 is GPIO0.</p>

The peeled back plated through hole on one pad shorted to the next. The slants between the holes indicate a very blunt router bit cut them out.<p>To be fair I boungt in the past other Sparkfun products have been really excellent.</p></p>

The downside is that we had a lot of boards pre-ordered and we are working through orders in the order that we received them. Hopefully you will be able to get your package soon!</p>

Check the features tab, it has two areas of breakdown. Now, you might ask, how do we get to 20? I asked the same question. There are 18 0.1" pins that are multifunction, there are also two pins available in the Qwiic connector that <em>could</em> be used for I/O.</p>

Customer #1650333 on DEV-17717 - SparkFun Pro Micro - RP2040Customer #1650333urn:uuid:77562cb6-6e48-330a-037d-cb5e69f741452021-03-15T08:50:47-06:00<p>Just had these show up and it looks like there's a manufacturing defect with them. The copper on the castellated edges is peeling and flaking, and completely fell off of at least one of the pads. I thankfully wasn't planning on using the castellated edges so it's not a big deal for me, but definitely something others who are need to be aware of. Hopefully this is just a bit of teething problem with this new product and Sparkfun fixes it quickly.<p>Edit: Sparkfun support says (via the forums) they haven't had any other reports of this problem, but that if anyone else is seeing this to let them know.</p></p>

(I know its hard to predict, just want to know if its like in a week or month)<p>Thank you soo much</p></p>

I know this is pre-production, but it'd be great to be able to start designing custom boards with the RP2040 even with the caveat that the circuits have not been tested and therefore the design cannot yet be guaranteed.</p>
