This is true, although UBECs are also packaged with some filtering caps, and are in a nice heatshrinked package usually -- so I look at it the other way around; packaged UBECs are so cheap, if you can make do with them, it's too easy to just grab them off the shelf and move on with life rather than DIYing it from components.
All depends how many of whatever you're building, I suppose.
- peteforde 7y agoI did a quick search and wasn't able to find anything even close to the price of the UBEC we used: http://www.banggood.com/External-Brushless-BEC-UBEC-3A-5V2-5S-Receiver-Power-Supply-p-949258.html http://www.banggood.com/External-Brushless-BEC-UBEC-3A-5V2-5... However, I cannot state enough that the price of this small component was simply not where the costs accumulated on this project. We geeks have a nasty tendency to over-optimize things that just don't matter in the big picture. You totally nailed it when you mentioned that this device is a packaged (and QA'd) product. The fact that it just slips right onto a Pi's GPIO pins without requiring any further modification is what makes this such a win. If you have to do anything to [70 units of] a component to make it work, you're blowing up any miniscule price arbitrage anyhow.
