The AEAK micro SD card module might not work. It is intended for 5V systems and has a voltage regulator. The TF card version looks even worse.

Try powering it from the 3V3 pin anyway, it might be OK like that.

This version works well.

while the SD card module shown above does indeed have an onboard 3v3 regulator, that regulator is just there to provide clean 3v3 power to the SD card, nothing else. there is NO level-shifting IC present, which has in the past been the source of problems.

What is the thinking of using the module OpenLog from sparkfun, it requires only TX beside power of 5V.

cheers
