Let me start by saying I'm writing this because a lot of people don't know how to setup UART (Universal Asynchronous Receiver / Transmitter) for their PS4, this tutorial is only for those who have a SAC-001 Motherboard following the previous SAA-001 board details.

Tools you would need:
  • A set of screw Drivers to open up the PS4
  • Soldering station $30-$150 (depends what you get)
  • Solder 0.7mm - $7
  • Flux - $5 - $15
  • Kynair Wire- $7
  • Wire cutters - $12
  • (Optional) Hot Glue and Glue gun - $15
  • Tip cleaner - $10
  • ANY Cheap FTDI USB to TTL Serial Adapter
  • Micro-USB Cable
  • etc
Step 1:

After you have your tools buy any cheap FTDI USB to TTL Serial Adapter I bought this one.

(Optional) Hot glue the wires to the motherboard so they dont come un-done when you put the PS4 back together

Step 5:

Put the console back together WITH THE WIRES HANGING OUT

Step 6:

Solder the ground wire to Ground on the device and the TX Wire from the PS4 to the RX Pad on the FTDI Device (Pic of the one i bought0

Spoiler: PS4E4 Information

Great job, actually for getting UART logs you only need 2 wires, the GND and Tx from PS4 mainboard to the Rx on UART2USB converter or to teensy.
The RX port on ps4 receives the information but all characters are replaced by 0x20 (SPACE) and we can only see how the cursor moves while the kernel displays events. So you are right, it's useless for now.

PlayStation 4 developers use it to obtain PS4 crash dumps for examination, for example Qwertyoruiopz was working on mapping techniques for dumping PlayStation 4 UART debug logs in attempt to bruteforce commands via the syscon to obtain more information on the PS4 system controller.
 
Nice tut. I fitted mine the other week but I didn't want any wires showing externally. Managed to make a pretty clean external port for easy connection using a micro usb cable.

I uploaded some pics for anyone interested.
