==> See layout guidelines

TJA1049 8 SOIC with 5V supply and 3.3V IO:
http://www.nxp.com/documents/data_sheet/TJA1049.pdf

Supply: LM2940-N IC REG LDO 5V 1A SOT223
==============> THIS HAS REVERSE BATTERY PROTECTION ELIMINATING 1 COMPONENT!!!!!!
Input cap: CAP CER 0.47UF 50V X7R 0805	C0805C474K5RACTU



Reverse protection diode:

SparkFun uses MBRA140 (1A, 0.56V drop, 40V reverse)

OpenXC uses RS1J (1A, 1.56V drop, 600V reverse)

  ==> Use MBRA140

0.016 width for power supply trace

Make VCC plane around regulator (both sides if possible) and use a bunch
of vias under the case to transfer heat.


MicroSD card => Just connecto to SPI (no external interfacing needed)
