First of all, I noticed that the module can draw up to 100 mA of current at a point.In my application this module is tied to the same 3V3 rail as other sensors, a display and a Bluetooth module.
A subpar picture of the hardware
The module runs on fumes (74HC4050), but the CARD could use up to 150mA.
Why don't you use the module's onboard 3.3volt voltage regulator.
Which Arduino do you use, and where is your code.
Link does not work.
