This is a combined Power over Ethernet (PoE) and Uninterruptable Power Supply (UPS) base board for the Raspberry Pi Compute Module 4 (CM4), offering you multiple power supply options alongside a host of other great breakouts and features.

The UPS feature uses three 18650 batteries (batteries not included). It can charge the batteries and provide power output for the system at the same time from the external power supply. It automatically switches over to the battery output if the external power supply is unavailable, keeping the system running without any trouble. 

The board also supports Gigabit 802.3af Power over Ethernet (PoE), allowing you to power your project from a PoE injected Ethernet cable. If PoE isn't right for your project just yet, you can also use the DC input port (7-36V) or the 5V USB-C port.

Power options aside, the board also offers:

  • M.2 M-KEY Slot
  • Built-in RTC (Real-time Clock) - CR2032 battery required
  • Colour-coded 40-pin GPIO header
  • Dual HDMI (4K 30fps)
  • 4x USB 2.0 ports
  • Single 22-Pin DSI port for a DSI display
  • Dual 22-Pin CSI port for camera modules
  • Micro-SD slot
  • Header for CM4 cooling fan
  • Programmable button
  • Power switch
  • BOOT selection switch
  • Activity LEDs for both data and power

Note:

  • CM4, Power supply and batteries not included
  • The onboard CSI and DSI connectors are 22-pin 0.5mm pitch, it is recommended to buy a CSI adapter and DSI adapter for use with the camera

Features

  • Designed for use with the CM4
  • Enables wireless power supply of the module and additionally three external power supply options: USB, DC and PoE interface
  • Circuit-protecting against overcharging/discharging, short circuits, and reverse polarity
  • Equipped with a Gigabit Ethernet RJ45 connector, integrates a PoE circuit compliant with the 802.3af standard (5V / 2.5A)
  • Equipped with M.2 KEY slot for connecting NVME SSD or communication module with PCIE M.2 KEY interface
  • Charges the batteries and simultaneously powers the system from an external power source
  • Automatically switches to battery power in the absence of an external power source, thus ensuring trouble-free and continuous operation of the system
  • Built-in CSI and DSI connectors have 22 pins with 0.5mm pitch, it is recommended to purchase a CSI adapter and DSI adapter for use with the camera and display with 15-pin connectors with 1mm pitch
