Photon Battery Shield With Solar Panels

Yes there s the 5 3 3v via the photon regulator but prior to that there s also the boost circuit from a single.

Photon battery shield with solar panels. You ll also be able to monitor battery levels using the photon itself which makes the power shield the best way to untether your wireless project. Be sure that the rounded edges of the photon line up with the rounded lines on the battery shield. In keeping with our mission we use rec solar panels. There is a know issue on the v2 1 0 of the power shield where the shield will fail to power up the photon when the battery is inserted for the first time or reinserted after a long time 60mins.

Be careful with the jst connectors and avoid pulling the wires particularly when removing them. Besides the on board usb port you can also use an external dc power supply or solar cell to charge the battery. Based around the mcp73871 battery management controller this shield allows you to simultaneously power a photon and charge a connected li ion or li po battery. This shield ships with a 3 7v 2000mah li po battery and headers.

Connect the tmp102 temperature sensor to photon battery shield pins with the. Just make sure your power source isn t higher than 5 5v. You ll also be able to monitor battery levels using the photon itself which makes the power shield the best way to untether your wireless project. The photon does have an efficient 3 3v regulator so does the adafruit 500c s tps61090 boost regulator 90 500ma but it s just me feeling icky that the raw battery voltage gets regulated twice to power up the photon.

Colorado solar power installer highest quality solar panels under the sun. Besides the on board usb port you can also use an external dc power supply or solar cell to charge the battery. Plug the photon into the photon battery shield. Check that the photon powers on and connects to wifi.

Of course you ll need the battery shield and a photon. This shield ships with a 3 7v 400mah li po battery and headers. Connect the battery and solar panel to the respective connectors. I m in the same situation waiting for particle s solar solution in jan and would like to try my hand at a diy solution in the mean time.

But now i need to add a solar panel to give the battery a boost. These are the highest quality most cost effective solar panels available. The photon battery shield equips your photon with just about everything it should need to use a lipo battery it even includes headers. Electronics particle photon microcontroller sparkfun photon battery shield tmp102 digital temperature sensor 2 5 w solar panel polymer lithium ion battery 6 ah if you live in a sunnier climate than seattle you can use a lower capacity battery e g.

This ll allow you to charge the battery with a 5v wall adapter or even a small solar panel. I have the sparkfun power shield for the photon now and have a 1000mv battery connected to it and it s running my photon just fine.
