USB to UART Power PCB v2.

Just finished designing another version on my “Breadboard Buddy”, This version includes the CP2102 as the old one did but i have removed the switches in favor for jumpers… longer life time. also removed the USB output pins since its used by CP2102 there is no need for it to be there.The voltage regulator will be a SOT223 instead of DPAK .. will allow 500mA @ 5v (USB) and 500mA @ 3.3v (REG).

I also placed caps next to output pins for a clean supply. I removed the LED mainly to preserve any little current it takes… if you think the led should stay comment here…

The board will also have a nice clean look to it.

Playing with textures for the 3D board…

    Looks clean. I’d always leave pads on the PCB for an LED even if people choose not to include it on assembly.

    No fuse on the USB line, just to be sure? Surprising also that the part needs no inductor or external capacitors.

      Thanks, smart idea with pads being left on. This board wont be made anymore, I actually have a new one coming up.

      This is the pdf for CP2102:

      Page 11: has more details. I actually have 2 caps on board for that ic.
      No fuse mainly to keep cost down and really not needed. I have tested my design for months now with not 1 issue 🙂

      I think people are going to love version 2. I call it the Breadboard Buddy 2.
      Its awesome!

      As soon as boards come in ill take pictures. Thanks for the comment 🙂
