* ELEC 301 - IMU
* ELEC 301 - IMU Board Rev 1.4
Added a 10K Ohm NTC thermistor and wired SPI_NSS to CS
-Added new schematic component NTC THERMISTORS 10KOHM 1608 SMD
-10K Ohm NTC Thermistor connected to VCC, PA3/AN3, and GND
-Connected PA4/SPI1_NSS to CS on the IMU
* ELEC 301 - IMU Board Rev 1.5a
Several changes to the schematic diagram:
-Added an op-amp and RC filter to the thermistor signal to reduce leakage
currents and reduce signal noise
-Added an off-board duraclik connector to connect to an external thermal
sensing unit
-Added a 3V LDO to the duralick connector
-Organized schematic into sections
TODO:
Update PCB to reflect the updated schematic.

-Added more GND vias
-Fixed silkscreen on bottom layer, and labelled all test points according
to the SPI interface
* ELEC 301 : Rev 1.5c
-Added testpoints to 3V LDO Vout, and the output of the op-amp contained
in the temp sense circuit
-Fixed some clearance constraints.
* ELEC 301 - Rev 1.6
-Saving progress for board reviews
* ELEC 301 : Quick Save
-Saving progress for rev 1.6
-Moved all analog components to use 3V from the LDO
-Moved some components around to create better ground plane coverage
