Subject: RE: Oberon and the OberonStation (retro-style FPGA computing)
Do you have 5 volt I/O with the OberonStaion
FPGA?
I was thinking of using it as general FPGA card.
The serial port is 3.3v according to the website. I haven't attempted to use
the serial port or the GPIO pins, but I believe they are all 3.3 volts for the
Spartan 3 series. Check the data sheet for the FPGA to be sure. There are
no level converters on the board, so whatever the FPGA provides is what
you get.
BTW, as of this writing, the website is showing the fully-assembled boards as
available.
