NanoVision & NanoBerry Miniature Computer Vision Evaluation Kits Released For Arduino & Raspberry Pi Platforms

NanoVision and NanoBerry evaluation kits

AMS (Austria Mikro Systeme) known for their array for micro sensing solutions and most importantly the NanEye, a Miniature CMOS image sensor which is designed for applications where size is a critical factor has also launched a set for evaluation kits called the NanoVision and the NanoBerry for the development of solution based on the AMS NanEyeC miniature image sensor. NanEyeC Camera Sensor The NanEyeC comes in a footprint of just 1mm x 1mm surface mount, and it can produce 100kpixel resolution up to 58 frames/s. It seems the NanEyeC is based on the NanEye series, which typical (NanEye) features a 249×250 resolution with a high sensitive 3um x 3um rolling shutter pixel and capable of a high frame rate of about 43fps to 62fps. The NanEyeC sensor is based on the high-speed LVDS data interface. The sensor is assembled with a unique lens and cover glass, which fits in […]

$55 ODROID-GO Advance Linux based Retro Game Console is Powered by Rockchip RK3326 Processor

Last year, Hardkernel took some time away from Arm and x86 Linux SBCs with the launch of ODROID-GO retro game console powered by Espressif Systems ESP32 processor. The console could be programmed with the Arduino IDE, and the $32 price tag made it a popular item despite the limited processing power fo the ESP32 dual-core processor. The good news is that the console got an upgrade with ODROID-Go Advance equipped with a Rockchip RK3326 quad-core Cortex-A35 processor coupled with 1GB RAM to run Linux, and featuring an upgraded 3.5″ wide-viewing angle color display.

This Business Card is a $3 Linux Computer Powered by Allwinner F1C100s SoC

The smallest, thinnest Linux computer There are many business card-sized SBCs, like RPi 4. But George Hillard, an embedded systems engineer decided it would be interesting to build an actual business card that was a computer. His card runs Linux and houses an Allwinner F1C100s carrying an ARM9 processor with 32MB RAM and 8MB flash storage. The Basics It holds some of his photos, a copy of his resume and a couple of games, which is pretty good for something like a business card. There is a USB port off one corner, and the unit can connect to a computer and boot up in about 6 seconds and shows up under USB as a flash drive.  But that piggybacked computer-attached display is really the only type of display the card can manage. The Shell and Linux Version The shell has the games, including a version of 2048, and a small […]
