Charge with 5 6v dc usb or 6v solar panel.
Solar panel charging adafruit.
Use any 6v solar panel.
Low battery indicator fixed at 3 1v with led output.
Automatic charging current tracking for high efficiency use of any wattage solar panel.
Will always draw the most current possible from a solar cell up to the max charge rate.
200 these panels come to us from voltaic systems makers of fine solar powered bags and packs.
Once you ve done that you can simply plug in the solar panel into the dc jack look for the pwr good led to indicate that the solar panel is providing power and then plug the battery into the batt slot in the left.
Combine a properly sized solar panel with the adafruit usb dc solar lithium ion polymer charger and a lithium ion battery and your project will stay powered with energy from the power of the sun.
Plug the battery into the batt port using a 2 pin jst cable and the solar panel into the dc jack.
The charger chip is super smart and will reduce the current draw if the input voltage starts to dip under 4 5v making it a perfect near mppt solar charger that you can use with a wide range of panels.
Set for 500ma max charge rate can be adjusted from 50ma up to 1a by soldering in a resistor.
To connect the panel to the adafruit solar charge controller a barrel jack adapter is needed.
Use only 3 7v 4 2v lithium ion polymer batteries.
We cannot guarantee this will work with solar panels purchased elsewhere.
Stick the fuzzy side to your bag neatly and aligned with the size of your solar panel then mate the scratchy hook side of the velcro to the fuzzy side peel off the adhesive back and gently press on your solar panel.
Three color indicator leds power good charging and done.
Solar charging is easy don t forget to prepare your solar panel and solder in the electrolytic capacitor beforehand.
Use two pieces of adhesive velcro tape to secure the solar panel to your bag.
A 2 1mm adapter cable is also required to adapt a solar panel to the dc power jack.
You can power another project like a mintyboost at the same time by connecting to the load output port.
Put the solar panel outside and keep the battery out of the sun it needs to be kept shaded to start charging.
Using larger panels either higher voltage or current output could also damage the charger.
The adafruit universal usb dc solar lithium ion polymer charger can use usb dc or solar power with a wide 5 10v input voltage range.
3 7v 4 2v lithium ion or lithium polymer battery charger.
These are waterproof scratch resistant and uv resistant.
Please purchase this kit and panels from adafruit to ensure optimized functionality.
