I got the following lipo module from aliexpress, hoping to use it with a meter of ws2812b led strip.
5V DC-DC Boost Converter Module 2in1 Lithium Battery Charger Discharger Board Step-up Converter for Camera UPS Power Supply
So far its working well however i have a small issue, using the module to charge the lipo battery: the module has no usb input port. And i have no micro usb connectors to solder onto anywhere.
Would it be possible to use any pins of an arduino to give power to this module so that can charge the connected lipo battery with a simple usb cable? Im using a pro micro at the moment.
I would be worried about the amount of power you are pulling through it. If you read through this you will see the maximum they recommend pulling through the vcc pin is 400mA.
Of course I didn't ask which board you were hoping to use but I think you will find 1 amp is too much to pull through any of the boards. You certainly couldn't do it through any of the ouput pins.
If I was in your position I would be tempted to "repurpose" a spare usb lead and solder that onto the board.
Im using it with arduino pro micro and 2000mah lipo battery.
My main concern is that i couldnt figure out how connections would need to be.
At the moment lipo modules Output (Ontput typo in above photo) is connected to ws2812b leds and arduino's 5v pin in parallel and powering both without issues. Im not sure if i can also connect the vcc pin of arduino to modules input at the same time, therefore if would charge when i plug a usb to arduino.
