Keeping it to just rerouting the 3.1 to the larger footprint would (hopefully) aid in both making it quicker/easier to do and in not needing to find stock of whatever this or that new components - it may even be possible to lay out in such a way as to work with the existing bed of nails if it can allow the new real estate to just poke out at that end.ДЄ bit unfriendly to lesser skilled & tooled people but I am willing to bet that most people bugging you for the Teensy ++ 3.1 are reasonably capable and this could be a comfortable enough (for most parties) way of cutting to the chase for this one hopefully not much time needed on it so you can get back to concentrating on the next generation Teensy you really had in mind and that wiki I'm about to return to my experiments I don't really appreciate you quoting me this time. Hey Paul, would it be very hard against your grain to lay out the Teensy 3.1 circuit in the much sought after 48 pin footprint and then just build one or two to test, no bed of nails, not that great a burden on PJRC resources - post the board on OSH Park (or where-ever that was I saw a lovely little collection of boards offered via them from you) and (perhaps) offer to sell a set of components required? At this point, real debug capability is by far the most commonly requested feature. This, and that it's less convenient but still not too difficult to get to those bottom side pads when necessary.ДЇrom PJRC's perspective (I'm assuming a lot of things here) it probably makes more sense to focus on the ++3.1, as opposed to devoting development time to the 3.1. This is also a pretty common response I hear.

I have to (try to) choose wisely.Д«ut, to be honest: I needed these bottom-pads only one time (two of them). Only a small fraction of things everyone wants can get done. The hard part is fitting the massive number of very different requests into a fixed number of hours per day. Releasing any new product, even something seemingly simple, uses up quite a lot of time that necessarily delays other stuff.ДЄfter all, PJRC is a commercial enterprise and most companies listen to the wishes of their users/customers. Time is the really precious, limited resource. like a debug version and a ++ board with that new 180 MHz part and new USB types and about 100 feature requests on the audio library and adding write support to the improved SD library and a biopotential sensor library and setting up a wiki and someday even putting serious work into really improving the website. The 2 biggest concerns are the financial investment to make large enough batches for Teensy's normal low pricing (on a model that's unlikely to sell much), and spending time working on this, rather than things many people want much, much more.

but I can assure you, that's not some effortless natural talent. Robin and I are actually pretty good at it. If you look around most of the hobbyist hardware market, lots of products go out of stock regularly. What you don't see is an incredible around of unglamorous hard work. Much like olympic figure skating, done flawlessly, it looks easy.

I think ongoing product manufacturing, from forecasting sales to purchasing to inventory management to actual production to testing & packaging to actual shipping as sort of an art form. It's all do-able, but it adds up to quite a lot of work. it's quite a bit more involved then 'and be done with it'. But when you add on building a new bed-of-nails test fixture, ordering PCBs and scheduling production of product, increasing the ongoing complexity of scheduling parts far in advance so no Teensy goes out of stock, and lots of other little behind-the-scenes things that all have to happen correctly. The actual engineering doesn't take too long, maybe a few days to lay out the PCB and build/test it. This is exactly my thinking, except we program the mini54 chip. I'd just wonder if it's worth the time and effort put into it, as it's only cost effective (especially with the added cost of the pre-programmed bootloader chips) if you make a LOT of them at a pass - and it seems like the regular Teensy 3.1 is enough for the majority of people.
