Good buy, quality item.
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.

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

Everything is great, except the boot button.
My only complaint is why didn't DFRobot make the boot switch usable via an external set of pins?Now whenever the battery fully dies I have to open up the device it's embedded in and try to press that micro button before it will work again. Which means I also have to design the mounts so that I can reach that tiny button when I inevitably will have to press it.The ability to turn off and on the 5v pins via the EN pin is a great feature, but the it would be nice if the USB port's always on power could be connected though a set of external pins (so that it can also be wired to an external on/off switch).A jumper that could disable all the LEDs on the board would also be nice.An onboard voltage divider connected to the battery leads with an external output pin would be a great edition so that we can check the battery voltage via an Arduino's analog pin easily. (my guess is that this already is available somewhere in that circuit already there's just no external access to it)Hopefully some of these suggestions make it into version 1.2 :) (which I will also purchase)

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

Very effective mppt controller!
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.đź‘Ť

nice
Has all the features, well made

Efficient
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.
