| Dec 18, 2022 at 21:13 | comment | added | bask185 | I use these boards alot to power 5v servo's. I made a footprint for these boards and I solder them flat to my own designs like a backpack. So far they have not exploded... What intrigued me a little bit is that they supposedly can supply up to 3A (not tested it myself) and they don't have an elco on board. So either it is lacking and you are to add an elco yourself or it is simply not needed. | |

| Dec 18, 2022 at 21:06 | comment | added | Andy aka | In case you are thinking of reverse engineering a design like this, the best approach is start from scratch with reputable sources that have a QA system and are supplemented with decent data sheets. Simulate and build. If on the other hand you have blown the module up and are looking for a replacement, you might just be perpetuating a poor design by fixing it. | |
