Web3-Pi has developed the Web3 Pi UPS for the Raspberry Pi 5 used as an Ethereum node, designed not to be mounted on top of the Pi. Connected to the USB power line, the device draws power from USB-C PD, a barrel jack or a replaceable Sony camera battery and provides an output of 5 V and 5 A. It communicates with the Pi, enabling power status monitoring and automatic shutdown when necessary.
Why it matters
For those using the Raspberry Pi 5 as an Ethereum node, this hardware focuses on the question of how operation should be managed during power outages and changes in the energy source. Rather than being mounted on top of the Pi, the device connects to the USB power chain, making it possible to use an external power solution without changing the physical structure of the existing setup. Support for different power inputs expands the available usage options by ensuring that the setup does not remain dependent on a single energy source. Monitoring the power status and enabling a safe shutdown when necessary aim to limit operational problems that could result from the node shutting down in an uncontrolled manner, going beyond merely supplying power. The fact that the LTE option does not yet appear to be fully implemented indicates that the scope of the connectivity features depends on the development status.
