I have acquired a digirig mobile v1.11.  
I found the video for the mod on PCB v1.9.  
I see some things have been moved but all the pads seem the same.  
No previous work has been done on the board.  
Will just shorting the 3V3 be enough as I have illustrated on attached photo for the TX500 on the V1.11?  
Many thanks

Yes, shorting 3V3 pad is the only mod you’ll need for TX500.
