Compute Module IO Board with PoE Feature, for Raspberry Pi CM3 / CM3L / CM3+ / CM3+L

Description Links

The Compute Module PoE Board is a development board which you can plug a Raspberry Pi Compute Module into, and make use of the resources of Pi more flexibly. With the PoE (Power over Ethernet) feature, and versatile onboard peripheral interfaces, it is suitable for evaluating the Raspberry Pi compute module, also is an ideal choice for end products.

  • Raspberry Pi GPIO header, for connecting sorts of Raspberry Pi HATs
  • 10/100M auto-negotiation Ethernet port, with PoE enabled
  • 4x USB ports, allows connecting more USB devices
  • 2x CSI camera interfaces
  • Onboard HDMI / DSI interfaces for connecting displays
  • Onboard USB TO UART, for serial debugging
  • Cooling fan interface, auto run on power up OR controlled by IO pins
  • Adopts isolated SMPS (Switching Mode Power Supply)

  • Power supply: micro USB port / PoE Ethernet port
  • PoE power input: 37V ~ 57V DC in
  • PoE power output: 5V 2.5A DC out
  • Network standard: 802.3af PoE standard
  • Dimensions: 114mm × 84.4mm
  • Mounting hole size: 3.2mm

Q The Netherlands Corneille ConsultDear Opencircuit , I have ordered this CMIO module for evaluation. I am trying to load an image into the EMMC memory of the CM3 + that I have put on the board. Unfortunately, I cannot see the combo as a USB disk. I've tried everything. From a Windows10 laptop with rpiboot.exe and Win32DiskImager and Etcher, a Linux Mint laptop with rpiboot / usbboot and dd / Etcher, a MacBook PRO with Etcher. In all systems rpiboot goes fine and the CM3 + enters phase 2 status (ready to receive image but unfortunately none of the laptops sees the CM3 + as a USB disk. The process stops as soon as the green LED on the CMIO module goes out. Etcher stays in " initializing device "status hang. USB data cable and USB power supply already changed but without result. The jumpers are as indicated all 4 to the left. What am I doing wrong? View 1 answer   |   Answer this question
