Raspberry Pi Zero 2 W Development Board
Quad-core Linux in a footprint smaller than a business card. The Zero 2 W runs full Raspberry Pi OS, accepts Python scripts and compiled ARM64 binaries, and connects over WiFi without any configuration ceremony. Ships from US warehouse, in stock.
The RP3A0 system-in-package puts a 1GHz Cortex-A53 quad-core and 512MB LPDDR2 on a single die, same architecture as the Pi 3, compressed into the 65mm x 30mm Zero form factor. Idle power draw is around 0.4W, which makes it a practical choice for solar and battery builds where a Pi 4 would drain your pack before morning. The CSI-2 connector is fully compatible with all official Pi camera modules, including the Camera Module 3 with autofocus.
Things to build with this
- Wildlife camera trap with cloud sync: pair a Camera Module 3 with a PIR sensor on GPIO, write a Python boot script that triggers JPEG capture on motion and pushes timestamped files to an S3 bucket over WiFi. The CSI-2 interface and 1080p capture capability are what make this viable at this power budget.
- Portable wardriving node: attach a USB OTG hub with a GPS dongle and a second WiFi adapter, run Kismet to log SSIDs with GPS coordinates, and sync capture files to a remote server on reconnect. The OTG port and compact form factor let you tuck this into a backpack or vehicle without drawing attention.
- Mosquitto MQTT broker on a solar cell: run Mosquitto on Pi OS Lite, pull I2C sensor readings across the GPIO header, and pipe data to a Grafana instance on your local network. At 0.4W idle, a modest LiPo and a small panel keep this running indefinitely in a weatherproof enclosure where a Pi 4 would not survive the night.
Key Features
- Processor: 1GHz quad-core 64-bit Arm Cortex-A53 (RP3A0 SiP, same silicon as Pi 3)
- RAM: 512MB LPDDR2 SDRAM mounted on-package
- Wireless: 802.11b/g/n WiFi + Bluetooth 4.2 with BLE integrated
- Video: Mini HDMI output up to 1080p60
- USB: Micro USB OTG port for peripherals and power input
- Camera: CSI-2 connector compatible with all official Raspberry Pi camera modules
- GPIO: 40-pin 2.54mm header footprint, compatible with Pi Zero HATs (header not pre-soldered)
Frequently Asked Questions
Does the GPIO header come pre-soldered?
No, most Zero 2 W units ship with the 40-pin header unsoldered. A standard through-hole 2.54mm header and a basic iron will get it done in under 10 minutes. If you need it pre-soldered, look for the 'with headers' variant from select distributors.
What operating systems run on this?
Raspberry Pi OS Lite is the most tested and lowest-overhead option. Ubuntu Server 22.04 for arm64 runs well if you want apt parity with your other servers. DietPi is worth considering for single-purpose deploys where you want to strip the image down further.
How does this compare to a Pi 4 for a headless server role?
The Zero 2 W idles around 0.4W versus 3W or more for a Pi 4. You give up USB throughput, Gigabit Ethernet, and raw core performance. For light workloads like MQTT brokering, sensor logging, camera capture, or simple web endpoints, that tradeoff strongly favors the Zero 2 W in any power-constrained setup.
Can I use existing Pi Zero cases and HATs with this?
Yes. The Zero 2 W shares the same PCB dimensions and 40-pin header footprint as the original Pi Zero, so mechanical enclosures and HATs designed for the Zero form factor are compatible.
Why we stock this
Curated by Kindly Morrow. We test and vet every product before it hits the store. If we wouldn't use it in our own builds, we don't sell it.
Things to build with this
