HDZero Goggle Reboot With Crossfire/ ELRS 868 & 900Mhz

HDZero Goggles can reboot if you bring 900Mhz or 868Mhz RC system either next to the goggles or the power cable. Repair 1 - To prevent reboot via power cable install ferrite bead around power cable where it enters goggles, this will stop reboots when you bring RC close cable. Repair 2 - To prevent reboot happening even when close to the goggles Install 0.1uf capacitor either across power switch or on RH RF PCB as Shown
