The tiny Arm Linux board comes with up to 4GB RAM, 16GB eMMC flash, and either AP6212 or AP6256 wireless module. plus all interfaces from Raspberry Pi Zero W, but with a twist as the mini HDMI port is replaced by a micro HDMI port, and USB-C ports are used instead of micro USB ports.

Radxa Zero preliminary specifications:
SoC ? Amlogic S905Y2 quad-core Cortex-A53 processor @ up to 2.0 GHz with Arm Mali-G31 MP2 GPU
System Memory ? 512MB RAM, 1GB, 2GB, or 4GB LPDDR4
Storage ? MicroSD slot, optional 8GB or 16GB eMMC flash
Video Output ? micro HDMI port up to 4Kp60
-
Connectivity
USB ? 1x USB-C 2.0 OTG port, 1x USB-C 3.0 host port
Camera ? 1x CSI camera connector
Expansion ? Color-coded 40-pin Raspberry Pi compatible header
Power Supply ? 5V via USB-C port
Dimensions ? 65 x 30 x 5mm (same as Raspberry Pi Zero W)
The only missing feature is the MIPI CSI camera, but for everything else, Radxa Zero offers much better specifications depending on the selected memory, storage, and wireless module compared to Raspberry Pi Zero W.
The board should run Android and works is being done on Armbian/Twister OS, and other operating systems. From a software perspective, it`s a "G12A" platform, a reference you`ll find in the Linux kernel for example, and compatible with Amlogic S905X2.
Radxa has already manufactured 100 samples, some of which will be sent for free to developers to help with porting low-level software to the board. That also means the board is not quite ready for the "general public" just yet, and we may have to wait for a few more months.
As a side note, It`s not the first quad-core providing an alternative to Raspberry Pi Zero W, as Banana Pi M2 Zero was introduced in 2017 with an Allwinner H2+ quad-core Cortex-A7 processor up to 1.0 GHz, but again Radxa Zero will be much more powerful here.
