I am thinking about migrating my current (though neverending) project from T3.6 to T4.1.
Unfortunately I made use of almost all Pins of the 3.6 so I am running in some issues - which means I have to use every single pin T4.1 has to give.
I am sure I am not the only or first one who asked this but I could not find very much helpful information here. Correct me if I missed something.
Bottom Pads: (I will not need more RAM or flash memory)
Has anyone tried to solder a 1.27mm SMT pin header to the pads? Like this one:
https://www.digikey.de/de/products/detail/amphenol-cs-fci/20021121-00008C4LF/2209054
After some measurements this should work.
SD Card Pins: (I will not need the onboard SD card reader)
This will be more complicated I guess. I found tall-dogs solution:
https://www.tindie.com/products/loglow/micro-sd-breakout/
But this seems to be no longer available. And I am not sure how long lasting this will be if the device is used in a somehow not very solid (=car) environment...
If there was no card reader installed (like on the T4.0) it would be possible to connect e.g. some flexible pcb to these pins.
I think I will have to reduce the functionality of my device to save some pins, but at the moment I am trying to anything to find another solution.
Any weird ideas?
