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)
