Internal Pads
It is not documented yet what use the pads have (e.g. Service Connectors, SPI, I2C, JTAG, PCIe etc.)

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
MediaCon UART
Pin | Name | Description |
---|---|---|
GND | Ground | |
UMC_TX | MediaCon UART Transmit | |
UMC_RX | MediaCon UART Receive |
Note: quite similar to PS3 Syscon UART
