SD Card Voltage Level Translator for nRF52811

[bardia3000]

Hello, I'm using nRF52811 and It works with 1.8 voltage on it's VCCs. Is it possible to use a micro SD? Should I use a voltage level translator (for example TXB0108)? I know there is example in SDK16 ("...\examples\peripheral\fatfs") explained the code.

Hi,

Using a voltage level translator is required and should work. The device you mention seems to have the correct specs. You will also need a boost regulator to power the SD-card if you do not have a 3.3V domain in your system already.

Best regards,
