900mA MPPT Solar Panel Controller - Solar Power Manager Module for 5V Solar Panel - Support Solar and USB Charging

Worked well for what I needed.I used this for a solar project for my son. It has all the connections that you would need and is very well made. Good price for a good item.

I use these to power solar Meshtastic LoRA Nodes. I have a 5v6w solar panel and 3 21700(4500mAh) cells in parallel. Output to the Meshtastic node. It has been up on my tower for 3 weeks and it has kept the batteries fully charged even during sub freezing Temps and multiple days of cloudy conditions. Very happy with the DFRobot controller. I have bought 6 of these now and would buy more.👍

Works very well, I have prime and should be free shipping but shipping cost was added to the product price. For same money can buy on DFrobost at least you don’t have to prime membership.

I bought this to control my 5v solar panel and battery charging for my Meshtastic device. So far this has been excellent at keeping my 10k mAh battery charged. Not only does it do great at charging in low light, the built in safety features are worth it as well.

been running several of these for meshtastic solar nodes, they work great and I haven't had a problem at all. totally worth it.

got 3 of these. one didn't work. two work, but charge the battery really slow because it's less than an amp

Has all the features, well made

This board is extremely efficient with a 5 watt panel and a RAK 4631. I charges the battery up to 4.21 volts and manages to keep it peaked on very overcast days. Great combo with a 6,000 mAh battery.
