PCB Pads:
Primary side:
- TXD0, RXD0 these are incorrectly label on the pcb, they are actually UARTTXD1 and UARTRXD1
- CTS0, RTS0 (apparently extended to cartridge port)
- L16 (nCS0 PM0)
- A4 (PH5/ETHERTX1 I/O General Purpose I/O Signals -- Port H5; multiplexed with Ethernet Transmit Channel 1)
USB Pins:
- A16 USBDN I/O USB Data Negative (Differential Pair output, single ended and Differential pair input)
- A15 USBDP I/O USB Data Positive (Differential Pair output, single ended and Differential pair input)
Secondary side:
- Test1
- Vss
- Test2
- CS1 bridge (SMT pads for 0-ohm resistor with a line between them) opposite the big CoB blob
- M4 (PB4/SSPRX/I2SRXD/UARTRX0/UARTIRRX0) Port B4; multiplexed with SSP Data In, I2S Data In, UART0 Serial Data In, and UART0 Infrared Data In
- 1V8 (most likely 1.8v for the cpu core)
