Review on Waveshare Solar Power Management Module with MPPT Function for 6V~24V Solar Panel and Battery Charging through Solar Panel/USB Connection Featuring Multi Protection Circuits by Rudy Santos

I find this board very useful for prototyping devices that will be temporarily connected to or completely removed from the electrical infrastructure. Stations, but there are other microcontroller projects higher on my priority list, so I use it as a power supply/UPS alternative for higher priority projects. The board was available for the 18650s. I can buy one specifically to try and modify for the 18650s. Another project!
