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)
