The Sailor Hat for Raspberry Pi (SH-RPi) is a versatile power management board designed for the Raspberry Pi and similar single-board computers. With the SH-RPi connected, you can create deeply integrated servers that shut down safely when power is turned off and wake up automatically when power is restored.

SH-RPi supports all Raspberry Pi models with a 40-pin GPIO header (every model since the Pi 1 Model B+). Additionally, it is compatible with Raspberry Pi Compute Module 4 boards and other single-board computers that have a 40-pin Raspberry Pi-compatible GPIO header or an external I2C interface with a 5V power input.

The documentation site has details on the hardware and software features of the board.

This repository contains the KiCad hardware design files for Sailor Hat. There are two other related repositories: firmware and daemon.

The documentation site is at docs.hatlabs.fi/sh-rpi. The devices are available for purchase at shop.hatlabs.fi.
