Pi Zero UPS HUB HAT for Raspberry Pi Zero Series, 3-Port USB 2.0 Expansion Board with Power Backup, 18650 Ba-ttery Holder, Smart Charge & Discharge Management

Overview The Pi Zero UPS HUB HAT combines a UPS (uninterruptible power supply) and 3-port USB 2.0 hub into a single compact module, designed to enhance the performance and reliability of Rasp-berry Pi Zero systems. It provides continuous power delivery and multiple USB expansion options, ideal for IoT, automation, or portable applications. This module ensures your Pi Zero remains powered during unexpected outages. With a power-path charging chip, it automatically switches between external input and the connected 3.7V 18650 ba-ttery without rebooting the system. You can safely run your applications or record data without the risk of corruption caused by sudden power loss. The integrated 3-port USB hub expands the Pi Zero’s limited connectivity, allowing you to connect a variety of devices such as flash drives, sensors, and input peripherals. A physical mode switch lets you toggle between Normal HUB and Pi Zero HUB modes, making it versatile for different usage scenarios. Built-in LED status indicators clearly display power and communication activity for each USB port, along with ba-ttery charge and discharge status. The boost converter circuit ensures a stable 5V output, while the ba-ttery monitoring chip helps track voltage and current in real time — perfect for developers who need performance feedback in low-power environments. With its reverse-connection protection and reliable circuit design, this UPS hub board is safe to use and easy to install. It directly connects to the Pi Zero via pogo pins or headers, keeping the setup neat and compact.
