Datasheet

Charge with 5-6V DC, USB or 6V solar panel!

Too dark out? Use a USB mini-B cable (http://adafru.it/260) or a 5V DC

adapter (http://adafru.it/276)

Automatic charging current tracking for high efficiency use of any wattage

solar panel

Use any 6V solar panel (6V seems to work best, 5.5V may work, 5V does not work)

Three color indicator LEDs - Power good, Charging and Done

Low Battery Indicator (fixed at 3.1V) with LED output on (labeled CHRG)

Set for 500mA max charge rate, can be adjusted from 50mA up to 1A by soldering

in a resistor

Will always draw the most current possible from a solar cell - up to the max

charge rate!

Smart load sharing automatically uses the input power when available, to keep

battery from constantly charging/discharging

Temperature monitoring of battery by soldering in a 10K NTC

thermistor (http://adafru.it/372) (not included) - suggested for outdoor projects where

the battery may get hot (50°C) or cold (0°C).
