The smallest, cheapest way to run real Linux. Pi Zero fits a 1GHz BCM2835 and 512MB RAM into a board half the size of a Model A+ - right-sized for headless automation, GPIO control, and embedded builds.
No built-in wireless on this model. Need WiFi onboard? Go for the Zero W or Zero 2 W instead.
Specs
| CPU | Broadcom BCM2835, 1GHz single-core |
| RAM | 512MB |
| Storage | microSD card slot |
| Video | Mini HDMI + composite video header |
| USB | Micro USB OTG (data) + micro USB (power) |
| GPIO | HAT-compatible 40-pin header (unpopulated) |
| Camera | CSI connector (v1.3 boards only) |
| Wireless | None |
Budget for the extras: microSD card, mini HDMI adapter, USB OTG cable, and a 2 × 20 header if you want GPIO.
