Additional UARTs
#1
Posted 13 February 2011 - 11:30 AM
I am looking for additional UARTs. So far I've found a single SPI/I2C->UART breakout board from Sparkfun and a dual UART (same, SPI/I2C) IC: SC16IS762 and a matching shield project <- I doubt that this one is in production or something.
Are there any other options? A quad UART would be nice . I guess only realistic option at this time is using 4 Sparfkun boards.

Miha, happy to see there are friends closer than oversea!
Well, about the quad-uart...
Take a look at these chips: I think could fit for your probelm.

Hi neighbour!
From what I can read on MAX3111E it looks to me like it has a single UART (and a RS-232)? Is it possilbe to use RS-232 like one or more uarts?

The Netduino might a 3rd uart somewhere. The Netduino COM1 is actually the dbgu. Uart0 is the COM2. The uart1 is at PA4 and PA5 I think.
I recall something about this - that there is a driver under development for utilizing it or something.
I find it odd that there are no easy solutions to this problem (like a quad UART chip or two double chips on a breakout board or something) giving the fact that a lot of components communicate through TX/RX.

What about this one?

The problems are: how much does it cost?...when will be available?...will you able to hand-wiring a 48-pin QFN package?...
Ciao!

Great project!...I'm trying to do something similar for my child, Lego based, but I have very few time...
Indeed, time is very scarce everywhere.

Now we are talking.

I don't think cost is a problem. However availability is a problem and bloody QFN package is even a bigger one. Are there any QFN -> normal package adapters out there?

If you're a soldering wizard (with a super-thin solder), you may try to connect a 48-pin DIP socket to the QFN wire-by-wire. I'd never able to do, but there's people able to make surgery on ants...
Mah!...try this:

Good luck!

For example Proto-Advantage has QFN-48 to DIP adapter, but in general those are not cheap.Are there any QFN -> normal package adapters out there?
