The Radxa Zero 3W is a single-board computer that measures just 65 x 30mm (2.6″ x 1.2″) and features a Rockchip RK3566 quad-core ARM Cortex-A55 processor with Mali-G52-2EE graphics and an integrated neural processing unit.

First unveiled in October, the Radxa Zero 3W is available now for $15 and up from Arace, and should be available from Allnet China soon. Its wireless capabilities also got a pre-launch upgrade.

When the Radxa Zero 3W was first announced, it was expected to feature WiFi 4 and Bluetooth 5.0, but now the units that are ready to ship actually have WiFi 6 and Bluetooth 5.4.

This isn’t Radxa’s first rodeo. The company launched a first-gen Radxa Zero in 2021, but the new model has a faster processor and support for up to twice as much RAM.

The Radxa Zero 3W features:

  • Processor: Rockchip RK3566 processor
  • RAM: 1GB to 8GB of LPDDR4 memory
  • Storage: microSD card reader plus optional eMMC 5.1 (8GB to 64GB available)
  • Ports:
    • 1 x USB 3.0 Type-C host port
    • 1 x USB 2.0 Type-C OTG port
    • 1 x micro HDMI
  • Other I/O:
    • 40-pin GPIO header
    • MIPI-CSI camera connector
  • Wireless:
    • WiFi 6 WiFi 4 
    • BT 5.4 BT 5
    • Antenna connector

If you’d rather have an Ethernet jack than WiFi, Radxa’s got you covered. the Radxa Zero 3E is a nearly identical board that trades the wireless radio for a Gigabit Ethernet port.

As for the Zero 3E, it comes in a variety of configurations, although only a few are available for purchase at launch.

  • 1GB RAM / no storage for $15
  • 1GB RAM / 8GB eMMC for $20
  • 2GB RAM / no storage for $20
  • 2GB RAM / 16GB eMMC for $30
  • 4GB RAM / no storage for $30
  • 4GB RAM / 32GB eMMC for $45
  • 8GB RAM / no storage for $45
  • 8GB RAM / 64GB eMMC for $65

You can also add $1 to the purchase price to get a set of GPIO pins mounted to the 40-pin header.

The system is designed to work with a 5V/1A USB-C power supply, supports 1080p/60 video output.

  1. How is it that an entire computer with WiFi 6 and Bluetooth 5.4 sells for less than an M.2 wifi and bluetooth card? Could the Radxa Zero 3W be connected to an M.2 slot with some sort of adapter?

  2. Great. Can it suspend to ram and resume from sleep? So tired of ‘low power’ devices that I have to slog through a boot process to use.

  3. I have been wanting to test-drive Armbian on RK3566 and this looks like a nice board to do that. I also like how 1GB ram is the minimum… wake-up Raspberry guys.

    1. Still waiting for this to become available… I want to run this in USB device mode with XRDP.

      1. Presently available at arace.tech, but they want $12 for shipping of a $15 item using either a credit card or Google Pay. I would prefer Paypal and $5 shipping (just like Aliexpress).

        1. AllnetChina is also $12 shipping, but has Paypal. I guess I will have to order a bunch to lower the per item shipping cost.

  4. This is definitely interesting. Stock for the Pi Zero 2 W has been way worse than the normal Pi 4 boards, and it’s looking quite long in the tooth (especially since it’s limited to only 512MB of RAM). Between the increased memory and the processor jump — 4xA55 @ 1.6 GHz in the RK3566 vs 4xA53 @ 1 GHz in the RP3A0 — this board should be quite usable for general-purpose work. It won’t be as fast as a Pi 4 with its A72 cores, but still. If I can get hands on it for a sane price, it’ll definitely be a potential replacement for the Zero 2.
