Just got a couple of these USB and serial enabled LCD backpacks from Seeed, and am having issues with the serial port.
I do have it working with the USB port, so I know the backpack and lcd screen work together.
BTW, there isn't any splash screen when it powers up, so I don't know what the firmware version is. The label on the Seeed antistatic bag has a date code of 01/17/15 on it.
I've searched the web pages on this site and the products pages, but haven't been able to find the following:
What is the default baud for the serial port?
What baud rates are supported?
How do I change the baud, if the default isn't what I need?
My goal is to hange a bluetooth module onto the serial port for a bluetooth display module.
