Hi Ian, what changes are you expecting to make in the BP7 (vs. BP6)?

So first of all, this isn’t anywhere close to release. It’s just a group discussion that creates prototypes as a byproduct. The first routed board was completed in October or November but there were no RP2350B to buy, and I wasn’t going to buy a full reel of broken silicon under the prerelease program for prototyping if there was a chance they might have a stepping.
There’s a couple threads discussing what people are interested in. I couldn’t find the main one earlier, so posted where you saw it.
We have a current completed PCB prototype with:
Note on this one: all those I2C chips are properly brand name and not cheap! This is a fantasy BOM because the new additions almost double the current BOM cost. It is not cost optimized, but more a luxury board with excessive perks
There is a revision under way with some ruggedizing:
This is where our discussion left off, around the holiday when everyone got busy/was away from keyboard.
At this point I’m very happy because we got a small quantity of rp2350B and can finally spin some REV0 boards. Then we can test it, see what the firmware build out will take, etc. As you can see, this is not a priority project, more a hacker space hobby horse with no actual timeline.
I may attempt to round up the rev7/BP7 threads tomorrow, but I really want to get the IR stuff done as it’s taken 4* as long as I anticipated.
am i the only one who likes saving stuff to sdcards ;-/ please dont retire my attic revision 8 firmwarez
It’s still supported! Glad you like it.
As usual, once these are ready for release, I’ll purchase immediately.
May I recommend one additional item?
And also… integrate this into the current BP6 manufacturing process, because it has benefits for the user and for issue triage.
I’ll create another linked post with initial thoughts for BP6 OTP programming.
I just ordered a bunch of RP2350 PICOs to test this with (since OTP programming is … mostly one-time), so while it’ll be a week or so before I can test, I think it’s going to be fairly straightforward.
