Here are the PCB layout files in Post Script. The zip file also contains Schematic and Overlay for the project.

Later in the day, I can upload them here and then you can make them available , where ever you want them to be.

I also have, a PCB for the RS232 out, but I guess, that's not as important as this one. I would also be posting it here, along with the file.

Breakout boards / Auto Switching, Self Powered USB <> RS485 using MCP2200

May 04, 2011, 12:18:16 am

I have successfully made a Self switching, Self powered USB <> RS485 using the MCP2200 Breakout Board.

I have successfully tested it (@ 9600) and it works

Here are the details.

Thanks,

In that case, I use the Rx/Tx status LED for switching the RS485 Send/Receive.

I was wondering if I could use the GPIO pins on the chip , without extensive programming.

Breakout boards / MCP2200 breakout board RS485 USB bridge

March 17, 2011, 09:45:22 pm

I wish to use this Breakout Board to build a RS485 <> USB bridge and was wondering if I could use the RTS/CTS pin to switch the Rx/Tx pins on the RS485 Chip.

There's some mention of these PIN on at http://http://dangerousprototypes.com/docs/MCP2200_breakout_board but I am not able to follow.

Any suggestion as to how I can go about with the idea.

Wondered if the BP3 could program a generic 32MB/64MB CMOS SERIAL FLASH CHIPS ?

I have some .vfo files which I want to program and I am thinking of the BP .
