== Summary ==
The CM-IO-POE-BOX is a composite breakout board that works with Raspberry Pi Compute Modules CM3, CM3L, CM3+ and CM3+L. It provides PoE power over a 10/100M Ethernet port, four USB ports, two CSI camera connectors, and HDMI/DSI display interfaces. The board uses an isolated SMPS, supports 27–57 V DC input via PoE, and outputs 5 V / 2.5 A.

== Technical overview ==
* Compatible with CM3, CM3 Lite, CM3+ and CM3+ Lite.
* PoE per 802.3af standard; input range 27–57 V DC, output 5 V / 2.5 A.
* Four USB ports for additional peripherals.
* Two CSI camera connectors; camera pins do not conflict with the 40-pin GPIO, unlike the official IO Board V3.
* HDMI and DSI interfaces for connecting displays.
* USB-to-UART interface via CP2102 chip for serial debugging.
* Cooling fan connection; can auto-run on power-up or be controlled via IO pins.
* Dimensions: 114 mm × 84.4 mm; mounting hole diameter 3.2 mm.
* Operating temperature range: −25 °C to 80 °C.

== Notes and version constraints ==
* The source contains outdated or unconfirmed claims about compatibility, electrical values, prices, stock, certifications, or warranty — these were removed or marked as uncertain.
* The 'Write image' step depends heavily on the exact CM variant (with or without eMMC); please verify the specific hardware variant before proceeding.
* Some steps reference software tools (rpiboot.exe, Win32DiskImager) whose availability and version are not confirmed in the source text.
* Camera numbering via the -cs parameter may differ from the silkscreen labels on the board; please test the actual mapping.
* For Bookworm systems, certain dtoverlay lines must be added to config.txt; this is version-sensitive.
* Please have any steps requiring human confirmation reviewed before implementation.
