Michael Tsai – Blog – Lightning Video Adapters



Lisa Braun :

Here is my little thread about Lightning Adapters – also known as Haywire – which are actually computers that have Apple Secure Boot and run Darwin kernel

Both support up to 1080p video output according to Apple and use the same SoC – S5L8747. The part number is H9TKNNN2GD and according to the iPhone Wiki it has 256 MB of RAM. Not much else is known about it

Unfortunately, these adapters are of terrible quality. HDMI adapter got 2 out of 5 stars on US Apple Store site, and reviews are all like this […]

Haywire doesn't store any firmware (well, except SecureROM), so iOS has to upload it every time . Firmware package for it is very small, around 25MB uncompressed. Shipped as a pre-installed asset with iOS and / or downloadable.

[…]

You can easily connect Haywire to your PC because it is basically a USB device. All you need to achieve is lightning and micro USB female breakout boards and few connecting cords […]

All these years later, and iOS video output over Lightning is still less reliable than using the old Dock connector adapter.
