Can someone check my eagle schematic for errors?

attached

Its a USB to RS232 Breakout board. It can be found in the examples in the ft232rl datasheet

Hi,

Please post the Eagle files (.sch and .brd) and I will look it over. Some errors won't show on a picture, so I'll wait for the design files.
Regards,

Why doesnt anybody use bus lines? They only take a couple of more minutes, but they do clean up a schematic.

I'll post the design files tonight when I get home.

Bus lines....I'm very new to eagle...only used it a couple days now.

Bus lines are mainly for parallel signals....
They won't do here.... :P

Post the libs... and we can get something!!! 8)
For whom the interrupts toll...

Check this man...
There are some corrections...
I don't know if your schematic is correct as far as the components go...
But I did some "CAD" corrections 8)

Thanks man, I needed some help cleaning it up ;)

As far as the circuit being correct, well i'll just have to test it on a breadboard before i send off the pcb

Hi,

Here's my take on what you have wired up so far.

Here's some advice, that could help you along...
Be carefull with your junctions (green dots on wires) and don't just sprinkle them on - if you see a junction where none should be, you might have more than one wire.

Place capacitors in a logical manner, to show where they belong (eg. close to the positive line when used as decoupling).
You used Vcc and Gnd. In digital circuits, you should use Vdd for positive and Vss for negative line. In analog circuits, it's Vcc and Vee respectively.
Gnd is for ground lines.

Søren

Wow thats really cleaned up.

I dunno what to call it but for gnd i need 0v, and voltage is 5v.

The only reason i labeled it vss on the jumper is because that is what the pin on the BS2 is called

Oh and one more thing....The MAX213 has vcc and gnd pins, 10 and 11, but they seem to be hidden....how does that work?
