I recently attached a Digi Xbee Wifi Module to the Fez Cerbuino that has the RP-SMA connector. The connector is too close to the USB host port. It’s so close that I have to take of the lock washer and nut just to fit it to the board. I had also purchased a Large RP-SMA antenna which definitely won’t fit.
This is just for someone’s future reference. I think the boards should only come with the vertical Usb Host.
If anyone has any ideas how I can fix this (even with solder) I’d be grateful.
you could also build/add a header “booster” shield for the xbee port to get it to a height that clears the other parts. This kind of part shadowing is not unusual when you have stackable devices; catering for every possible design is not overly practical or costs you in increased board area to get better clearances.
USB is very sensitive to trace length, so there’s a good chance using wires will cause potential issues. But Cerb family doesn’t support USB Host at this point, so unless you were embarking on that entire driver quest, you may not have a problem by removing the port.
[quote]The XBee socket automatically brings all sorts of wireless options to the table, including WiFi and ZigBee. Note that there is a size restriction on the physical size of XBee modules that can be used. Whip antenna, chip antenna, UFL antenna fit well, but the ones with RPSMA connector do not. Also plan your XBee selection well if you are planning on using full-size shields.
