Expansion Board CM4 PoE UPS Uninterruptible Power Expansion Board Gigabit Ethernet Dual HD Multimedia Interface Quad USB 2.0 Elevate your Raspberry Pi projects with our advanced CM4 PoE UPS Expansion Board, designed to provide reliable power management and enhanced connectivity. This versatile board is perfect for developers, hobbyists, and professionals looking to maximize the potential of their Raspberry Pi Compute Module 4. Discover the key features that make this expansion board an essential addition to your setup: Uninterruptible Power Supply (UPS): This expansion board supports an uninterruptible power supply, allowing for simultaneous charging and discharging. With dynamic route management, you can ensure a stable power supply for your projects, minimizing downtime and enhancing reliability. Standard CM4 Connector: The onboard standard CM4 connector is compatible with Compute Module 4 Lite EMMC series motherboards. This seamless integration allows for easy installation and ensures that your projects can leverage the full capabilities of the Raspberry Pi ecosystem. Dynamic Power Management: Experience enhanced power stability with dynamic route management. When connected to an external power supply, the board powers the system while simultaneously charging the lithium battery. If the external power is disconnected, the system automatically switches to battery power, ensuring uninterrupted operation. Comprehensive Protection Circuit: Safety is paramount, and this expansion board features an onboard protection circuit that guards against overcharging, over-discharging, overcurrent, short circuits, and reverse connections. Each battery is equipped with an independent self-recovery fuse, providing an extra layer of stability and safety for your projects. Multifunctional Communication: The board supports communication through the I2C interface, allowing you to measure critical parameters such as battery voltage, current, power, and remaining power. In the event of low voltage detection, you can program the Raspberry Pi to save data and initiate a safe shutdown, preventing data loss due to sudden power failures. Upgrade your Raspberry Pi experience with the CM4 PoE UPS Expansion Board. Its robust features and reliable performance make it an ideal choice for anyone looking to enhance their projects with stable power management and advanced connectivity options.
