Overview
The Raspberry Pi Zero W is a credit-card-sized computer that packs the full Linux experience into a board measuring just 65 × 30 mm and weighing 9.3 grams. Built around the Broadcom BCM2835 ARM11 processor at 1 GHz with 512MB of RAM, it runs the full Raspberry Pi OS (Debian-based) and supports the complete Pi software ecosystem.
The "W" designation marks the key addition: an onboard BCM43143 chip providing 802.11b/g/n WiFi and Bluetooth 4.1 Low Energy. This enables wireless connectivity without any USB adapter, making truly wireless embedded Linux projects practical. A camera serial interface (CSI) connector supports the Pi Camera module, enabling streaming and computer vision applications.
A 40-pin GPIO header footprint (unpopulated by default) provides access to GPIO, I2C, SPI, UART, and PWM — compatible with the full range of Pi HATs and expansion boards. Mini HDMI supports 1080p video output. Two micro-USB ports handle power and USB OTG (for connecting keyboards, USB hubs, etc.).
The Zero W runs Raspberry Pi OS and supports Python, Node.js, and any software available for ARM Linux. It is popular for embedded Linux applications that require WiFi connectivity, camera support, or full Linux capabilities in an extremely compact and low-cost package.
