Energy Harvester v1
Failed design, discarded. See e.g. Solar Harvester.
Energy harvester is an LTC3588-1 based board to harvest solar power and to store it into a super capacitor. Output voltage can be selected to be one of 1.8V, 2.5V, 3.3V, and 3.6V using two solder jumpers. For 3.3V and 3.6V output, two super capacitors in series can be used for higher voltage tolerance.
The board can be used with a Base Board or as a standalone. The board provides PGOOD signal to indicate good power output from the LTC3588-1.
9V battery can be used as a backup power for rainy days.
