Hi,
during holidays I'm taking a lot of photos. Before corona I used a notebook with card reader and connected my SSD via USB. In the evening I made copy action in hotel room. But I want to take less equipment with me.
A smartphone (Android) with TotalCommander and an USB hub with additonal power input is possible. Sometimes I have to remove card reader or SSD from USB host and attach again, because smartphone doesn't recognize them at once.
So my idea: take a microcontroller for that.
I see there is USBHost_t36 library for mass storage and a Teensy 4.1 has card reader.
A few pictures are on microSD, most are on normal SD cards. So I need card slots for both sizes.
On Teensy 4.1 board the 8 connectors from card slot are going directly to processor? No pins at the edge of the board?
Can you please tell me manufactor and type of card slot you use?
So easiest way is to use/make a "microSD Sniffer"? PCB should have same thickness like a microSD 0.7± 0.1 mm?
Bye
Jürgen
