sd-adaptor for teensy 3.*

[flipflop]

Hi,

Is it possible to avoid the 74LCX125 to make a more simple sd-adapter for the teensy 3.*?

regards!

As Headroom pointed out, the Teensy 3 already operates at 3.3V voltage levels, so it needs no voltage translation like 5V-based MCUs. In the link provided, Paul also pointed out that the voltage regulator inside the Teensy 3 can handle the power requirements of a SD card without issues. So, enjoy hooking up that SD card.

thanks!

Thanks!!!, in the link don't specify if the 10k resistor is needed, and the final question is... is the pullup 10k resistor (in the MISO pin) needed for some reason???

The SD library will work without the pullup resistor.

A new SD+Wiz820 adaptor is now available for Teensy 3. It connects the 4 signals directly, since Teensy 3 is 3.3 volt signals.

Yeah, I would love to know as well

Oh, lovely, thanks!
