What is Web3-Pi-UPS?

This open-source UPS delivers seamless DC power to Raspberry Pi 5 via a single USB-C cable that handles both 27W USB-PD delivery and data for telemetry and graceful shutdowns. It supports hot-swappable Sony NP-F batteries alongside USB-C PD or barrel jack inputs, with an OLED display for status and buzzer alerts—perfect for preventing node crashes during outages. Written in C, it runs on low-power MCUs for efficient, silent operation in tight enclosures.

Why is it gaining traction?

Unlike bulky AC UPS units or GPIO HATs that clash with cases, this sits inline between charger and Pi, skipping wasteful conversions for true DC efficiency. Developers love the real-time battery stats, remote monitoring hooks, and open-source hardware files for 3D-printed enclosures and PCBs—no vendor lock-in. As an open source UPS management software alternative, its 27W PD output matches Pi 5 demands exactly.

Who should use this?

Raspberry Pi 5 builders running 24/7 Ethereum nodes or solo staking validators, where downtime risks database corruption and lost rewards. Home labbers with self-hosted services needing reliable power without rackmount bulk. Pi cluster operators tired of fragile battery packs.

Verdict

Grab the firmware and hardware designs if you're prototyping Pi 5 uptime solutions—docs and renders are solid for a young repo with 18 stars. At 1.0% credibility, it's early; test thoroughly before production, but the dual-license (GPL-3.0 software, CERN-OHL-S hardware) invites community polish.
