Mrk 0.0, Alpha Release
First hardware implementation of the logger, functional but with higher than desired power consumption and some awkwardness with header orientation and component selection
Errata:
Sleep and power shutoff issue due to bleed through of power through SD card and external I2C lines, causing additional power draws
Workaround: None (use a bigger batter)
Additional power consumption caused by FTDI converter
Workaround: None (use a bigger batter)
