i’m working on a Full size SD Card Reader to fit into the expansion card, let me know if someone is interested to help out mechanic design and firmware design. My FW is a bit rusty because in the last time i mainly do HW electronic development
I finally manage to find all the electronic parts needed to do a USB C to SD card reader and i will have the schematic finished soon.
The hard part where the connectors, but with some mechanical modification i think i solved the connector problem: see attached pictures:
Things to do:
Schematic ( this is no problem)
Final Mechanic design → where to put screws on outside
FW design for the IC ( there are some examples, i think they just need to be adjusted to my HW)
Optional dual SD FUll size connector + uSD connector in same expansion card
( the connector will fit and the IC supports dual SD, only need to check layout if all electronic parts fit to PCB)
What do you think?
