The XPC nano NC1010BA is a highly energy-efficient mini-PC featuring an Intel Celeron 4205U processor from the Whiskey Lake U generation. Thanks to its low power consumption and numerous interfaces, this tiny device is a true all-rounder. Despite its relatively small form factor, it accommodates both an M.2 SSD (occupied) and a 2.5" SATA hard drive or SSD with a height of up to 15 mm. The black plastic housing fits perfectly on any desk and is hardly noticeable as a PC, with a volume of less than 850 ml. It can also be easily mounted behind a monitor using a VESA mount. The built-in SD card reader on the front supports SD, SDHC, and SDXC flash cards in standard format, and booting from these cards is possible. Additionally, the mini-PC features a serial interface for professional applications. This RS-232 interface with the traditional 9-pin DSub connector allows for the connection of cash register systems and products from science or industry. Up to two monitors can be connected simultaneously via HDMI and DisplayPort. The mini-PC supports 4K displays with a resolution of 3840 x 2160 Ultra HD at 60 Hz through the DisplayPort output. To achieve this, the memory must operate in dual-channel mode, requiring two identical memory modules.
