Q1) answer the following question regarding these two devices

MicroSD card breakout board+ by Adafruit https://www.adafruit.com/products/254

SparkFun Level Shifting microSD Breakout https://www.sparkfun.com/products/13743

a) Locate and analyze the schematics for the two breakout boards. You can find them starting at the links above. What appears to be the major difference between the two designs? (note: you have to be more specific than a different level-shifter chip was used, and I do not care about the voltage regulator or decoupling caps focus on the SPI lines)

b) Focusing on the DO (Data Out) signal of the SD card, what are the implications of each design as far as the ATmega644P is concerned? (hint: take a look at the ATmega644 datasheet as well as the datasheet of a typical SD card and perhaps the datasheets for 74HC4050 and TXB0104, all in the shared Box folder, and compare logic voltage levels VOH, VOL, VIH, VIL)
