Re: MultiWii EZ-GUI
A temporary fix that is working right now - I'm powering the board from one of the on-board motor ESC/BEC directly into the micro-usb port. This is allowing me to use EZ-GUI with the FC running on battery power. Had to make a pretty ghetto'sh patch cable but it's working now. I've ordered a 6.5v BEC...

Re: MultiWii EZ-GUI
Thanks for the link. I have a somewhat similar problem, albeit, it's much more exaggerated on my board.

Re: MultiWii EZ-GUI
It's a Multiwii Pro from Hobby King. m Have confirmed it's a flaw in the design of the board. The AMS1117 expects a 6.5v input. Problem is your typical ESCs are going to put out 5v. I've checked the voltage at the regulator and it's 5.0v going in and 3.97v coming out. Looks like there are three opti...

Re: MultiWii EZ-GUI
Looks like I'm stumbling onto a "well known" power problem with the MWC Pro board. The linear voltage regulator (AMS1117) exhibits a voltage drop of about 1.2 volts (at 100mA draw). Need to research on how to fix this. Short the input/output of the regulator? No sure yet. They say that onc...

Re: MultiWii EZ-GUI
I poked around the board checking voltages. With battery only (battery alone is showing 11.4v) the ESC powering the FC is showing 5.0v. When I check all of the 5v pins on the FC they show 3.97v. The 3.3v rails show 2.89v. When I plug in the latop USB cable they bump up to 4.6v and 3.3v respectively....

Re: MultiWii EZ-GUI
Android EZ-GUI app connects to FC (MultiWii Pro) through BT module but gives error - Warning: No Data Received (when powered through battery). The kicker is it works great if the FC is connected to the USB port on my laptop (while using android app through BT). Baud rates between the FC and BT Modul...
