I’m a bit unsure about how to connect a microSD to an EMX module.
I have read several related questions on the forum, but did not find an answer to mine.
The connector I want to use (Multicomp 460DE08C3) has the following pin layout:
Oh I see. No, I do not need card detect, because the card will always be in the holder. I will use it as storage for application settings and html files for the embedded webserver.
Your pin layout looks fine. But I would search a microSD slot with mechanical card detect switch, so you can detect insert/removal of the card. F.e. the DM3D-SF http://www.hirose.co.jp/cataloge_hp/e60900232.pdf
Thanks a lot! The link you send me in your first reply is very helpfull. I was a bit confused because the pin layout is diffrent compared to a “regular” SD card.
I I do not actually need CD for this project, but it’s likely that my next project requires it. I might as well do it right the first time…
I get started on drawing the Hirose connector in Eagle.
