Priced at $10, it brought full Raspberry Pi OS compatibility to an ultra-compact form factor suitable for IoT, wearable, and embedded deployments. Powered by the Broadcom BCM2835 single-core ARM11 processor at 1 GHz with 512MB of RAM, the Pi Zero runs a full Linux operating system from a microSD card. Version 1.3 was the first Pi Zero to include a camera connector (using the smaller Zero-specific flat flex cable), enabling projects that combine full Linux processing with camera vision without dedicated CSI adapters. Connectivity is provided through two Micro USB ports — one for power input and one for USB data (OTG capable) — and a Mini HDMI port supporting up to 1080p output. The 40-pin GPIO header is unpopulated (sold without pre-soldered headers), providing flexibility for custom installations. WiFi and Bluetooth are absent on this model (found in the Pi Zero W). The Pi Zero v1.3 is fully software-compatible with all other Raspberry Pi models running Raspberry Pi OS, supporting Python, Node.js, and virtually any Linux software. Its low power draw makes it ideal for battery-operated Linux projects, retro gaming handhelds, and embedded vision applications where computational complexity exceeds what a microcontroller can handle. ## Where to Buy - [Adafruit](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F2885&ref=openhardware.directory&product=raspberry-pi-zero-v1-3&source=md-export) — 10.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F2885&ref=openhardware.directory&product=raspberry-pi-zero-v1-3&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fadafruit.com%2Fimages%2Fproduct-files%2F2885%2FBCM2835Datasheet.pdf&ref=openhardware.directory&product=raspberry-pi-zero-v1-3&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Flearn.adafruit.com%2Fintroducing-the-raspberry-pi-zero&ref=openhardware.directory&product=raspberry-pi-zero-v1-3&source=md-export) ## Tags `raspberry-pi`, `linux`, `sbc`, `arm`, `bcm2835`, `single-board-computer`, `iot`, `embedded-linux` ## Images ![Raspberry Pi Zero v1.3](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-zero-v1-3/b990dc214c01.jpg) ![Raspberry Pi Zero v1.3](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-zero-v1-3/794b91314d23.jpg) ![Raspberry Pi Zero v1.3](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-zero-v1-3/cc19ac06c648.jpg) --- [View full device page](https://openhardware.directory/devices/raspberry-pi-zero-v1-3)
