Call to arms | Teensy + SDRAM = true

Note It was also true with AD_B1_14 that was T41 pin number
I put in maybe proposed numbers for the pins that are not MMOD pin numbers. Note: I renumbered the ones on the left
What I mean is B0_12 is pin 32 for T41, T40 and the micromod. There's no reason to give it a new pin number. Same goes for AD_B1_14, it is already pin 26 for all models.
 
Please confirm so that I made no mistakes. I posted to images (one rotated) to make it easier to read the upside-down stuff.

Something I can't wrap my head around. B0_12 is 46 or 32. How can it be one or the other? Software pins are the same everywhere aren't they?
Different Teensy boards have different logical mappings from their Arduino Pin numbers to the actual IMXRT Port/Pin number.

In this case B0_12
On T4.1 we see:

So it is pin 32. And you are right it is also pin 32 on MMOD:
3265B0_122.121:TX1_RX3IO-102:12LCD_DATA8

@KurtE B0_12 is pin 32 on the micromod, not sure why your spreadsheet gives it a new number and says 32 is for T4.1 only?
Because I goofed.
 
Yes, it might mean dropping off 5V or GND from the long headers on the side, but you have many more on the other 90deg connector.

I think you are close, the only things are:
You showed 32 and 32 on right hand side above...
Note: this has slight numbering issue in that we don't have a 46 now. But no biggy, I will leave it as duplicate of 32... Or could mark it bad...

Alternative is to decrement on the new numbers by one, but makes really no difference.
 
Is there anyone missing on the Big Contributer list?
I've sorted it by widest name first (my OCD...)
If not then I feel ready to order these.
 
When you have the boards is there any chance that I could buy one from you?
I am more interested in what you can bring to the community. As I am not the best coder in the world, I have taken it upon myself to give these out to people that can contribute. If we as a community can make things available for people and for Paul, that's huge value.

Especially if Paul decides to make a future Teensy 4.x or 5.x, then there's already tons of complete code to implement. Which benefits us all.

I've seen your name plenty of times, but it's better I ask you directly, even if it may sound weird.
Can you contribute? :)
 
Not deep down in the nitty gritty but only general top level ideas from a general user point of view, like for instance reducing the maximum length to considerably reduce the manufacturing costs. In fact I think with the current size you will get two PCBs for the cost of one (if the width is kept at 50mm..or a few microns less).

With JLCPCB 1 off 100x50mm PCB will be the same price as 2off PCBs at that size. So the PCB cost is halved.

Although I have had previous experience working with MCUs (50 yrs ago...gosh I feel old, but I was quite young then) at the assembler level, in recent times I have produced drivers for things (see here) but they have tended to be add-ons rather than at the MCU level.

The code looks better then mine, that's a plus haha. Rezo also tells me that you're quite helpful in the forum, that is also very valueable for the community.

You have a board! The batch will take a few weeks until I have them in my hand. Hopefully they have no faults.
Send me your address, email and phone (for notification) in a PM.

Gee that's good, thanks.

One thought comes to mind. I know you have taken the "Magic" capacitor off, but would it be worth while leaving the pads available for future use just in case it raises it's ugly head again!
 
That was a tight squeeze but CAN FD on alternate pins are added.
AD_B0_14 and AD_B0_15. All I need now are the pin numbers, then it's time to place an order!
