Mobula8 Repair: ELRS and Voltage Regulator Fix

My Mobula8 is flying again. First the ELRS receiver stopped working, so I added an external. Then the internal voltage regulator for 5V stopped working. First I tried to replace the tiny from another broken AIO. But it didn't work. Now I added an external IFlight BEC module to get 5 Volt and I can fly again.
