No, I'm still alive....stilll.....and still......
A 200 meter cable theft disconnected me from my lover internet for 10 days. And I got it back now.
Soyza, I'm sorry, I'm really sorry to tell you that. I know you have waited for my reply for a long time.
Now, come to the PCB, I've checked it,
1:- It's great.
2:- It's great.
3:- It's great.
But the things should be noticed:
1: If we use a general crystal, it needs two capacitor (22pF-33pF), but your PCB doesn't include it. I've fixed it.
2: the transistors in the main schematic were 2N390x which has a E-B-C layout. If we wanna use any other transistor instead we've to look carefully because it should be a C-B-E type. Your PCB is correct.
3: You placed a USB-A conector. But I think we should main the standard rule using a USB-B connector. Though if we use USB A for better availability, no complain there.
4: You forget to put C5 between U5V and ground.
5: C1 is a electrolytic capacitor. you used a non-polar instead. i used a electrolytic cap from eagles rcl libary.
I'll mail you the modified PCB soon.
