The official credits lists the parts on the board as Allwinner H5 SoC / CPU, Audio Codec, H3 Camera development board and Allwinner H3 GPU. The complete name is Allwinner A13 H3 development board and Allwinner H3 Camera Module.
The manufacturer claims a maximum resolution of 2592 x 1936 at 60 fps at 4:3 and also lists 1920 x 1080 p or 1080i @30, 2592 x 4800 @ 60, and 3840 x 2160 @90 FPS as second generation 4K options. The ARM Cortex A53 CPU is based on the Allwinner H3 SoC.
Cameras cannot be easily used directly, but the official documentation (by Allwinner) includes several examples, that allow you to find the V4L2 API for the camera. Listing 1 uses a standard Video4Linux2 V4L1.1 API for controlling the camera. After changing the resolution from 320 x 240 to 640 x 480, the app crops to the center region of the camera, leaving the top and the bottom black.
The Almond offers a capable Allwinner H3 dual-core SoC, Bluetooth, WiFi, gigabit networking, Ethernet, audio, a low profile microSD slot and digital expansion port, and increases the memory to 1GB. The Almond A64+ is not based on the Raspberry Pi 2 or 3, and it tops out at a measly 2560 x 1600. The only Raspberry Pi 2 option is the 650-pin P1 HAT. The Almond is the most expensive unit of the bunch, coming in at $61.50 the cheapest, $95 at most retailers. Retailers may not offer free shipping on the Almond. A 64GB, retail priced, microSD card now tops out at 2GB. SATA is optional, and the lone I/O port is a micro USB OTG.
The highest supported resolution is 2560 x 1600. However, it is not supported by default, because we need to customise a Facebook app to make it functional. Then you can only use it with desktop mode enabled. In this case you will see a slide out menu into your desktop on the left of the screen. 7211a4ac4a
