In case the title of this post didn’t give it away, this is a board that takes a low supply voltage, boost it up, and then regulate it back down to the correct voltage. In this case, 3.3V.
This board is meant to power an RGB LED matrix display that I’m working on. The input voltage will be coming from a pair of AA batteries.
I’ve recently been moving towards prototyping with surface mount components. Kinsten brand presensitized PCBs was my first choice. I did a lot of trials but the results were never really satisfactory. Maybe I was just being too particular. The PCBs that turned out should be functional, except they weren’t aesthetically pleasing.
So, after nearly exhausting my stock of presensitized boards, I decided it was time to turn to BatchPCB. From submitting my designs to receiving my PCBs was rather quick really, only about 3 weeks. I guess I got lucky. Check out some pictures I took of the PCBs after the break.
