UART
Same layout is used for SAA-K23, SAB-K02 / SAA-001, SAB-001 (pads are present on SAC-001 too, but layout slightly differs)
3.3V CMOS TTL - 115200, n, 8.1
UART0 Console
| Pin | Name | Description |
|---|---|---|
| GND | Ground | |
| U0C_TX | UART0 Console Transmit | |
| U0C_RX | UART0 Console Receive |
Note: quite useless, as the output is zeroed out by "spaces" on retail models
Southbridge UART
| Pin | Name | Description |
|---|---|---|
| GND | Ground | |
| TX | Southbridge UART Transmit | |
| RX | Southbridge UART Receive |
Note: quite similar to PS3 Syscon UART
