TinyZero and MicroSD Shield

Does the TinyZero work with the MicroSD shield? I just ordered these, and wanted to make sure they'll work together. My main concern was the 3.3 V coming from the TinyZero, which looks like it goes into another 3.3 volt regulator on the MicroSD shield. Does the regulator on the SD shield need > 3.3 volts to work?

Hi, realized this did not get a response- yes they do work together, and you're right that it's a regulated 3.3V into another 3.3V regulator. The regulators that we use are all LDO type and the voltage drop is very small(spec: 50mv @ 100mA).
