What I have:
CF 633 H/W v1.3 F/W v1.5, with the USB daughter board.
What I'd like:
I'd like to use this in an embedded project, driving it with an AVR. There is no USB host controller, but I've got plenty of UARTs.
I've seen a bunch of posts about removing the daughter board, which I'm willing to do. It's not clear to me whether the existing firmware on the 633 will work over the pure serial interface, or whether the 633 would need a brain transplant.
If I'm reading the datasheet correctly, I'm going to want JP11 and JP12 to be closed, and JP18 to be open, since I'll be driving the serial connection with the AVR's logic levels (3v0-ish, I believe). Correct? I'm guessing they may already be set this way if my assumptions about what's on the daughter board are correct, but we'll see.
Finally, I see no RoHS silkscreens on either the main or daughter board. The main board says Copyright 2002. Is it safe to assume this board is pre-RoHS? (Just trying to avoid, um, issues from my friends in the lab about contaminating their tools).
Thanks,
