About The System

The Avatar HD Goggles are a new digital FPV goggle made by Walksnail part of CaddX FPV.

These Goggles have been made in partnership with Fat Shark and are sold under both the Fat Shark and Walksnail brand.

They are both compatible with the Walksnail Avatar HD VTX and offer same/similar functionally.

About The System:

The Avatar HD Goggles are a new digital FPV goggle made by Walksnail part of CaddX FPV.

These Goggles have been made in partnership with Fat Shark and are sold under both the Fat Shark and Walksnail brand.

They are both compatible with the Walksnail Avatar HD VTX and offer same/similar functionally.

Important SOC Images Notes:

The main SOC is labelled as a Xilinx Virtex 5 XC5VLX50T - FFG1136FGU2033 - AC4284883A1 2C.

Based on code samples and SOC package it is strongly believed this is not this FPGA. Its believed to be a Artosyn RF Chipset such as the AR9201/AR8211.
