The new NanoPi M4 is the latest low-cost computer to launch in 2018 that modernizes the specs of Raspberry Pi-sized boards.
The NanoPi M4 improves on many of the specs of the $35 Raspberry Pi but at $65 is almost double the price.
Notable features include four USB 3.0 ports, a USB Type-C port, 2GB DDR3 memory, a six-core processor, support for 4K displays and hardware-accelerated 4K video playback, and 64 general-purpose input-output (GPIO) pins for hooking up hardware. It also includes an interface that supports two 13-megapixel cameras.

In contrast the Raspberry Pi uses slower USB 2.0 ports, has 1GB of slower DDR2 memory, a quad-core processor, can only output to 1,920x1,080 displays and has 40 GPIO pins.
While the Pi supports a far wider range of operating systems, the NanoPi M4 is listed as supporting Android 7.1, alongside Ubuntu 18.04 Desktop and Ubuntu Core.
The board's makers say the NanoPi M4 is suited to developing a wide range of software and hardware. The NanoPi M4 shares the same 40-pin header layout as the Raspberry Pi, as well as being the same size, so on paper should be compatible with some Pi-based hardware add-ons.
As with most single-board computers, it's worth noting that few boards are as accessible or offer the same breadth of stable software as the Pi. Some users of recent NanoPi boards have also encountered driver problems and system setup issues, so this board may be one for the more technically proficient.
