The result is 40% better single-threaded performance and five times the multi-threaded throughput compared to the original Zero W. Wireless connectivity mirrors the original: 2.4 GHz 802.11 b/g/n WiFi and Bluetooth 4.2 with BLE are provided by the BCM43436 combo chip with an onboard antenna. A CSI-2 camera connector accepts the standard Raspberry Pi Camera Module (with a ribbon adapter), opening the board to computer vision projects. A mini HDMI port and composite video test pads provide video output options. The 40-pin GPIO header footprint — unpopulated by default — is fully HAT-compatible with the wider Raspberry Pi Zero ecosystem of accessories, including the Camera Module adapter cable. Storage is provided by a microSD card, and the board runs the full Raspberry Pi OS (32-bit or 64-bit) as well as many lightweight Linux distributions optimised for the Zero form factor. At 65 × 30 mm and 10 g, the Zero 2 W is one of the smallest capable Linux computers available, suited to wearable cameras, smart IoT gateways, and embedded-vision projects where space and weight are critical. ## Where to Buy - [Adafruit](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F5291&ref=openhardware.directory&product=raspberry-pi-zero-2-w&source=md-export) — 19.05 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F5291&ref=openhardware.directory&product=raspberry-pi-zero-2-w&source=md-export) - [manufacturer](https://openhardware.directory/r?to=https%3A%2F%2Fwww.raspberrypi.com%2Fproducts%2Fraspberry-pi-zero-2-w%2F&ref=openhardware.directory&product=raspberry-pi-zero-2-w&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Frpi-zero-2-w%2Fraspberry-pi-zero-2-w-product-brief.pdf&ref=openhardware.directory&product=raspberry-pi-zero-2-w&source=md-export) ## Tags `raspberry-pi`, `zero-2-w`, `linux`, `sbc`, `wifi`, `bluetooth`, `arm-cortex-a53`, `40-pin-gpio`, `csi-camera` ## Images ![Raspberry Pi Zero 2 W](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-zero-2-w/cd04e6f3d26e.jpg) ![Raspberry Pi Zero 2 W](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-zero-2-w/e9841cf6467e.jpg) ![Raspberry Pi Zero 2 W](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-zero-2-w/099ffe9da488.jpg) --- [View full device page](https://openhardware.directory/devices/raspberry-pi-zero-2-w)
