UART Setup and Debugging for PS5

UART requirements

To perform UART communication on the PlayStation 5, you will need:

• an FT232RL module **or** a CH341A module configured for 3.3 V

 : Using a 5 V module will likely damage your console. See the gallery below for instructions on modifying your CH341A.  

• wires (≤ 20 cm / 7.8 in)

 : Longer cables can cause missing or corrupted log data during UART transfers.

UART pinouts by PS5 revision

Performing a UART connection

Connect three wires between your UART module and the PS5 console:

1. Connect TX (module) → RX (console)
2. Connect RX (module) → TX (console)
3. Connect GND (module) → GND (console)

It is crucial to match TX to RX; otherwise you will receive no data.

Using PS5 Nor Modifier

After wiring, connect your module to a computer and launch the external tool PS5 Nor Modifier:

• Source and downloads: GitHub – PS5 Nor Modifier

Follow these steps:

1. Open the application and select the UART Communication tab.
2. Click Refresh Port and choose the COM port for your FT232RL or CH341A module.
3. Click Connect.
4. Power on the PS5 by pressing its power button while the tool is open.
5. click Get Error Codes to display UART logs or error codes.
