Re: Is it bricked? Never read about this before

The 5V regulator supplies power to the 3.3V regulator... if you are seeing 3.3V at the test point , then the 3.3V Regulator is OK. So it appears that the 5V regulator is shutting down ... for some reason... If you have a 7805 and are confident in swapping out the two parts , then it is a quick way t...

Re: Is it bricked? Never read about this before

Yes , check the voltages first.. The 5V regulator is either bad or there is a short causing to much current draw , the regulator is shutting down , and then re-starting. Hence the blinking display... If it is good then the 3.3V regulator needs checked.. Also DO NOT grab the 5V regulator pcb when it ...

Re: Is it bricked? Never read about this before

The fuse is OK , or the READY LED would not light.

My best guess is you damaged the 5V switching regulator ...This could be replaced by a 7805 linear regulator for testing , as this in Not a SMT part.

Re: Use both Trainer-Ports simultaneous

The Futaba jack and the JR jack share the same Trainer port, so there is only one input.

Re: Arduino Due add on to 9X

Here is how the board is coming along..

I added a spot on the back to add some Open collector drivers .. for Haptic , LED backlight , and relay drive. There are solder pads
to access the required pins...

The USB signals are now brought out to a 5 pin header on the the 0.100" grid.
