A story as old as time, I know. I used to have no issues with FTDI based arduinos in the past with this PC, but for some reason I'm having issues now. The error is it shows up as Other Devices -> USB Serial in the device manager and "Device USB\VID_1A86&PID_7523\5&1beeb37f&0&4 was not migrated due to partial or ambiguous match."<p>I've downloaded the latest VCP driver from the FTDI website but I still get the same error. Have you run into this issue? Is it a windows update issue? Thanks!</p></p>

I would like to build a figerprint lock system with this board that is primarily powered by an account adapter with battery backup. I can figure out how to setup the figerprint part but I'm unsure if I can have a battery connected that will switch over when account is lost. Anyone of a tutorial to that end.</p>

This incarnation DEV-13975 of the RedBoard does not appear to be included in the table of boards listed in Sparkfun's Arduino Buying Guide linked sparkfun.com/arduino_guide at the end of this product description, even though the older RedBoard DEV-12757 is listed at the very top of that table as retired.</p>

Device there shown as retired. I didn't see this there, so didn't realise there were two, was confused. Took a while to notice the different product codes.</p>

The Arduino Pro and Pro Mini use a different bootloader so they are not considered Uno compatible (and have slightly different hardware). But both boards use the ATMega328 and so should be compatible. There will always be a few differences including ATMega328s not being able to run at 16MHz at 3.3V (and still be in spec).</p>

Is there a 3.3v "UNO" compatible solution?<p>I am typically talking to LCD modules that have many bi-directional lines, so 3.3v to 5v conversion chips are numerous and messy.</p></p>

When people were powering the board over anything other than USB there was enough power running to the chip that it affected the RX and TX lines. Now if the board is not powered over USB the FTDI chip gets absolutely no power. All in all the changes were all similarly small.</p>

I didn't spot any looking at the two versions of the schematic. Literally the only substantive difference I spotted was a change in the value of R2 (current limiter for power LED LED2) from 1k to 4.7k.</p>
