VIM1 is the original Amlogic S905X ARM development board designed by Khadas for hobbyists, makers and electronic lovers, which is also often referred to as an “Open Source TV Box”. It is tiny, and slightly smaller than a Raspberry Pi, with dimensions similar to that of a credit card. The VIM1 is only available in two versions: VIM1 Basic with 8GB EMMC storage and AP6212 (b/g/n) Wi-Fi, and VIM1 Pro with 16GB EMMC storage and AP6255 (b/g/n/ac) Wi-Fi. Both versions offer 2GB of DDR3 RAM and Bluetooth 4.2.
Like your conventional desktop computer, the VIM1 single board computer supports the booting of multiple operating systems. They say:
You can choose from a variety of OS images (ROMs) from our Khadas Docs or Community Forum. Popular OSes include: Android 7.1 / 9.0, Ubuntu 18.04, LibreELEC, Armbian, Buildroot, and so on. There are even dual-boot images, for developers to boot both Android and Ubuntu from the same EMMC.”
One feature developers will like is the built-in 40-pin GPIO, real-time-clock (RTC) and VIN port for an extra power supply. Also, the three user-buttons on the side enables easy access to power, reset and function keys. You can find full open source code on Github, and hardware schematics can be found in Khadas’ documentation. Khadas also includes a built-in power control unit for supporting power-cycling via a remote control.
