Re: help needed: Design works on Breadboard but not PCB

Replacing the zener diodes did not fix the problem. Although, I was able to confirm, on my breadboard, that if you use 200mW zener diodes instead of 500mW ones, it does not work. So currently I have the 500mW diodes on the PCB, but still no go. I guess the next thing to try is put the other through-...

Thanks for the reply.

I tried the hub idea, but there was no change. I hadn't thought of just mounting through-hole components on the SMD PCB. So, I'll try that; starting with the zener-diodes.

help needed: Design works on Breadboard but not PCB

First off, I'd like to to say thanks for software, it cut out a lot of development time. My problem right now (that I can't figure out) is that my design works perfectly on the breadboard, but won't on the PCB fabbed. I can program the microcontroller using the PCB, but the OS won't recognize the de...
