UPS Expansion HAT for LattePanda Sigma Single Board Computer

The LattePanda Sigma UPS stands out as a robust and flexible power backup solution crafted specifically for the LattePanda Sigma x86 Windows/Linux Single Board Computer Server. Equipped with four 18650 lithium-ion batteries, it ensures continuous power delivery, addressing sudden power outages with ease. The dual power input interfaces, Type-C PD (20V, 100W) and 5.5×2.5mm DC Jack (19-24V, ≥90W), offer versatility for diverse power configurations, making it a compact and efficient choice for applications like IoT systems, edge computing, and robotics.

An essential feature is its automatic power switching, bolstered by the HID-UPS protocol. The UPS seamlessly transitions to battery power when external sources falter, protecting the LattePanda Sigma from potential damage. This adaptation allows it to mimic a laptop's internal battery functionality, with operating systems recognizing it as a battery device. This recognition enables essential system power management features, such as power-saving modes and automatic shutdowns, thus optimizing efficiency particularly in power-sensitive situations.

An open-source integration with Arduino further enhances the UPS's versatility. Users can leverage this feature to develop tailored battery management systems, optimizing energy use and extending battery lifespans through customized charging voltage limits. This level of customization ensures the UPS adapts to specific requirements, enhancing its application range and longevity.

What differentiates the LattePanda Sigma UPS from conventional systems is its direct battery-powered design. By directly powering the LattePanda Sigma with its four 18650 batteries, it bypasses typical energy losses associated with boost or buck circuits. This direct approach not only maximizes battery life but also supports up to eight hours of continuous operation, depending on the conditions. Whether faced with brief interruptions or extended outages, the UPS consistently delivers reliable performance, proving indispensable in scenarios where sustained uptime is critical.
