SPI through level-shifter

Hi,

We have developed a mockup based on the Arduino board to validate some peripherals (ePaper & LoRaWAN modem). All went ok, with matching signals current for both devices (3.3V).

Now, we are being integrating the solution with Breadboards, so the signals have dropped down to 1.8V so we need level-shifters.

We did a first try with Adafruit's bi-directional voltage-level translator TXB0104, but only UART is working. SPI does not seems to detect anything.

Any advice or idea for SPI LLC? Thanks a lot in advance...

Hi mike.aski,

Thanks for your interest in the Intel Edison Platform.

I would recommend to check this thread , where some users discuss about different level shifters that they have used. Still, you should know that we haven't tested these devices, so they may or may not work.

Hope you find this information useful, have a nice day!

Best Regards,
