Waveshare PoE UPS Base Board Designed for Raspberry Pi Compute Module 4, Gigabit Ethernet, Dual HDMI, Quad USB2.0

Waveshare PoE UPS Base Board Designed for Raspberry Pi Compute Module 4, and supports POE power supply and 7~36V DC power supply, with four onboard USB2 .0 for user convenience. User Guide: Confirm the fan voltage before connecting, it support 5V and 12V. if you want to connect 12V by default, please modify the jumper cap of FAN_VCC USB Type C interface is used as the USB SLAVE interface to burn the image, and it can also be used as the power supply interface, but cannot be used as the OTG interface. The BOOT switch is for CM4 startup mode, the ON for CM4 to enter the programming mode, and the OFF for system to starts normally. In normal use, it is necessary to provide at least 5V 1.5A power supply for CM4. Otherwise, there may be problems such as automatic shutdown, frequency reduction and so on. USB2.0 is closed by default, if you want to open it, you need to add dtoverlay=dwc2,dr_mode=host in config.txt When using the POE function, pay attention to check whether the switch supports PoE of the 802.3af network standard. When you need to use POE, connect the POE jumper cap to the EN position. The Change LED light is the charging indicator, it is always on when charging, goes off when fully charged, and flashes when it fails. Multi Power Supply Options Dynamic Path Management, More Stable Power Supply Dimensions Features: H.265 (HEVC) (up to 4Kp60 decode), H.264 (up to 1080p60 decode, 1080p30 encode) OpenGL ES 3.0 graphics Options for 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM with ECC (see Appendix B) Options for 0GB (CM4Lite), 8GB, 16GB, or 32GB eMMC flash memory (see Appendix B) Peak eMMC bandwidth 100MBps (four times faster than previous Compute Modules) Gigabit Ethernet PHY supporting IEEE 1588 2 × HDMI 2.0 ports (up to 4Kp60 supported) Three external power supply options: USB interface, wide voltage DC, and PoE When connected to the external power supply, the system will be powered and the battery will be charged at the same time, and the battery will be in a disconnected status after being fully charged, so as to avoid battery life damage caused by frequent charging and discharging When the external power supply is insufficient, the battery will provide power output together with the external power supply at the same time to ensure the system normal operation When the external power supply is connected, the system will keep running normally even when the battery fails or is taken out. When the external power supply is disconnected, it will automatically switch over to batteries output without interrupting the system operation Packages Includes: 1 x Waveshare PoE UPS Base Board Designed for Raspberry Pi Compute Module 4, Gigabit Ethernet,
