Cheapest Raspberry Pi with Wireless: Zero W vs Zero 2W Compared

ByC Wilson Updated on
Raspberry Pi Zero W single-board computer with wireless capabilities.

The cheapest Raspberry Pi with wireless is the Pi Zero W at $10, which includes 2.4GHz WiFi and Bluetooth 4.1 in a board the size of a stick of gum. For most new builds, the Pi Zero 2W at $15 is the better choice: it is approximately 5x faster than the original Zero W, runs the full 64-bit Raspberry Pi OS Bookworm, and handles tasks like Pi-hole, AdGuard Home, MQTT brokers, and Node-RED flows that overwhelm the single-core Zero W. This guide covers the full spec comparison across all three Zero variants, honest use case guidance, and the correct Bookworm headless WiFi setup method.

Key Takeaways

  • The Pi Zero 2W ($15) outperforms the original Zero W ($10) by approximately 5x on CPU tasks despite sharing the same clock speed. The difference is architecture: the Zero W uses a single-core ARM11 (ARMv6), while the Zero 2W uses a quad-core Cortex-A53 (ARMv8). The $5 price difference is worth it for any project that needs to do real work. Buy the Zero W only if the absolute lowest cost is the constraint and the workload is genuinely trivial (a single sensor reading a few times per minute).
  • None of the Pi Zero models have an Ethernet port. WiFi is the only network interface. For projects where reliable networking is critical (a permanent DNS server, a home automation hub), a Pi 4 with Gigabit Ethernet is the more appropriate choice. The Zero W and Zero 2W are correct for embedded, portable, or space-constrained projects where WiFi connectivity is acceptable.
  • The Pi Zero W’s GPIO header is unpopulated (no pins soldered) by default at the $10 price. The Pi Zero WH ($15) adds pre-soldered header pins. The Pi Zero 2W ships without a header at $15. If GPIO access is needed for a Pi Zero 2W project, solder a standard 2×20 2.54mm male header yourself or purchase the Zero 2W as part of a kit that includes headers.

Cheapest Raspberry Pi with Wireless: Full Spec Comparison

Cheapest Raspberry Pi with wireless: Pi Zero W vs Pi Zero WH vs Pi Zero 2W specs, price, and best-for comparison

All three Zero models share identical RAM (512MB), WiFi band (2.4GHz 802.11n only (no 5GHz on any Zero variant)), and form factor (65mm x 30mm). The only Ethernet-capable Pi in this price range is the Pi 3A+ at $25, but it is discontinued. If Ethernet is needed at low cost, the Pi 3B+ (~$35 used) or Pi 4 (2GB, $45) are the correct choices.

The Pi Zero W and WH use the same BCM2835 SoC as the original Pi 1. The Pi Zero 2W uses the RP3A0, a custom package-on-package chip containing a Cortex-A53 quad-core processor and 512MB LPDDR2 RAM in a single unit. This architectural difference is why the Zero 2W is 64-bit capable (runs Bookworm 64-bit) while the Zero W is 32-bit only (runs Bookworm 32-bit).

What the Cheapest Wireless Raspberry Pi Models Are Good For

Pi Zero W: correct use cases. Battery-powered IoT sensors that wake, read, and sleep. Projects embedded in enclosures where power consumption and physical size dominate. Applications that run a single Python script doing one thing repeatedly. Basic MQTT publishers. Retro gaming handheld builds where 2D emulation is acceptable.

Pi Zero W: incorrect use cases. Pi-hole or AdGuard Home as a primary DNS server (too slow under load with multiple clients; the Zero 2W handles it). Node-RED flows with more than a few nodes. Any project that runs Docker containers. Video playback beyond 480p. Running multiple services simultaneously. A NAS or file server (no USB 3.0 and single OTG port limit throughput severely).

Pi Zero 2W: correct use cases. Pi-hole and AdGuard Home DNS filtering. Tailscale VPN exit node. MQTT broker. Node-RED automation flows. Always-on lightweight homelab services. Camera builds using the Pi camera module via the CSI ribbon connector. Projects that need a tiny Linux computer with enough headroom to do real work. For detailed Pi-hole setup, see AdGuard Home Raspberry Pi: Complete DoH, DoT, and Parental Controls Setup Guide.

Pi Zero 2W: incorrect use cases. Anything requiring Ethernet reliability (WiFi dropouts will cause problems for a DNS server that all household devices depend on. Use Pi 4 with Ethernet for that). Plex or Jellyfin media servers (CPU is too slow for any transcoding). Docker stacks with multiple containers. Builds where USB 3.0 throughput is needed.

Pi Zero WH: Identical to the Zero W in every specification. The only difference is the pre-soldered 40-pin GPIO header. Choose it over the plain Zero W when the project needs GPIO connections and soldering is not practical. Choose the plain Zero W when the enclosure design or embedded use means the header pins are unwanted.

Setting Up a Headless Wireless Pi Zero on Bookworm

Both the Pi Zero W and Pi Zero 2W are headless-first boards. Most builds have no display or keyboard. The correct Bookworm headless setup uses Raspberry Pi Imager’s advanced settings to configure WiFi before the first boot. The old wpa_supplicant.conf method is deprecated and does not work on Bookworm.

Download Raspberry Pi Imager from raspberrypi.com/software. Flash Raspberry Pi OS Lite (32-bit for Zero W, 32-bit or 64-bit for Zero 2W) to a microSD card. Before clicking Write, open the OS Customisation settings (the pencil icon) and configure:

  • Hostname (e.g., pizero)
  • Username and password
  • WiFi SSID and password, WiFi country code
  • Enable SSH, select “Allow public-key authentication only” and paste your SSH public key

Flash the card, insert it into the Pi Zero, and power on via the micro-USB power port (not the data/OTG port). After 60 to 90 seconds, SSH in:

ssh youruser@pizero.local

Expected result: The SSH connection succeeds and you are at the Pi’s shell prompt. Run hostname -I to see the WiFi IP address. If connection times out, check that the WiFi SSID and password were entered correctly in Imager and that the Pi Zero is within range of the router. The Pi Zero’s WiFi antenna is the thin trace on the edge of the board. A metal enclosure significantly reduces range.

After first boot, update the system and set a static IP via router DHCP reservation for any always-on service:

sudo apt update && sudo apt full-upgrade -y

# Find MAC address for router DHCP reservation:
ip link show wlan0 | grep ether

FAQ

What is the cheapest Raspberry Pi with wireless?

The Pi Zero W at $10 is the cheapest Raspberry Pi with built-in WiFi and Bluetooth. It includes 2.4GHz 802.11n WiFi and Bluetooth 4.1 on the BCM2835 SoC. The Pi Zero WH is the same board with a pre-soldered 40-pin GPIO header for $15. The Pi Zero 2W is also $15 but uses a quad-core Cortex-A53 processor that is approximately 5x faster than the Zero W. For most new projects, the Zero 2W is the better purchase at the same price point.

Is the Pi Zero W or Pi Zero 2W better?

Pi Zero 2W for most new projects. It is approximately 5x faster on CPU tasks, runs 64-bit Raspberry Pi OS, and handles workloads like Pi-hole, AdGuard Home, and Node-RED that overwhelm the single-core Zero W. Both cost $15 (the Zero W is $10 without a header but $15 with the WH header). The Zero W is only worth choosing when absolute minimum cost is the constraint or when the ARMv6 architecture is specifically required for legacy software compatibility.

Does the Raspberry Pi Zero have Ethernet?

No. None of the Pi Zero variants (Zero, Zero W, Zero WH, Zero 2W) have an Ethernet port. All network connectivity is via the built-in 2.4GHz WiFi. A USB OTG Ethernet adapter can add wired connectivity, but it uses the single data port shared with everything else. If Ethernet is needed, the Pi 3B+ or Pi 4 are the correct boards.

Can the Pi Zero W run Pi-hole?

Technically yes, but the Pi Zero 2W is the better choice. Pi-hole on the original Zero W handles a small number of DNS queries adequately, but the single-core ARM11 CPU struggles under load when multiple household devices hit it simultaneously and the web dashboard is very slow. Pi-hole on the Zero 2W responds quickly and handles a typical household load without CPU contention. For the complete setup, see AdGuard Home Raspberry Pi Guide.

Does the Pi Zero 2W support 5GHz WiFi?

No. The Pi Zero 2W only supports 2.4GHz 802.11n WiFi, the same as the original Zero W. This is a hardware limitation of the RP3A0 chip’s integrated radio. If 5GHz WiFi is needed for better throughput or less interference, the Pi 4 and Pi 5 both include 802.11ac dual-band (2.4GHz and 5GHz) WiFi. A USB WiFi adapter with 5GHz support can add 5GHz connectivity to a Pi Zero but adds cost and uses the single OTG port.
