Designing Raspberry CM4 IO Board
need to design an IO board for the raspberry CM4. The board should support a Poe interface 2 cameras, a single DI interface. The RJ45 needs to be mounter vertical. Needs one PWM fan interface. +3Volts, Gnd, GPIO12 adn GPI13 need to be brougth out to a right angle 4 pi connector . Position TBD.

How can I help with your CM4 baseboard project today? Options:
- Review the CM4 connector pinout and map key nets (USB, PCIe, HDMI, CSI/DSI, GPIO).
- Plan and add the power subsystem (+5 V input, 3.3 V/1.8 V rails, sequencing).
- Add connectors (USB-C, Ethernet PHY/MagJack, HDMI, MIPI FFC) and link nets.
- Check ERC/DRC and fix common issues (grounds, pull-ups, decoupling).
- Source parts for the DF40 mezzanine, ESD/TVS, regulators, and passives.
Tell me your goal and constraints (interfaces you need, power source, form factor).
