The HERO4 is the latest offering in the increasingly popular GoPro mountable video camera product line. With up to 240 frames-per-second, the HERO4 is the first camera of its kind to capture 4K ultra-HD video. This enhanced video capability paired with built-in Wi-Fi and Bluetooth® requires processors twice as powerful as the previous version. This TechXposed Teardown will take a look inside at the brains behind the most advanced GoPro yet.
