Break out I/O pins to RJ45 sockets.
Each RJ45 socket provides connections or 4 data lines, 2 GND lines, and 2 power lines. The power connection can be linked to either IOREF or VIN using a jumper.
Each data line has a 1k resistor in series to provide current limiting to the I/O pins.
- 2×6 (12-way) IDC headers for connection to I/O Breakout Shield
- 4 x RJ45 sockets
- Selectable power jumper to RJ45 sockets: either IOREF or VIN
