## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 8, longevity 100
- inputs: {"age_days": 3611, "days_push": 1557, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
periph is a Go library for peripherals I/O, providing pure-Go (no cgo) drivers and interfaces for GPIO, I²C, SPI, and 1-wire hardware on boards like Raspberry Pi, BeagleBone, and Jetson Nano. This google/periph repository is the archived original home; development moved to the github.com/periph organization, with the last usable version pinned at v3.6.8.

## Use cases
- control GPIO pins on a Raspberry Pi from Go
- read sensors like BMP280 or DS18B20 over I2C or 1-wire
- blink an LED or read a button without polling
- drive SPI displays like SSD1306 OLED from Go
- enumerate and discover available hardware pins at runtime
- interface with FTDI FT232x USB devices in Go

## When to choose
- you need pure-Go peripheral I/O with no cgo or external dependencies
- you are pinned to the v3.6.8 API and cannot migrate
- you want SemVer-guaranteed stable interfaces for GPIO/I2C/SPI on Linux SBCs

## When to avoid
- starting a new project - use the actively maintained repositories at github.com/periph instead
- you need support for newer boards or devices added after 2022
- you need non-Linux production-grade hardware support beyond hobbyist use

## Facets
- artifact type: library
