Olimex A20-OLINUXINO-MICRO Single Board Computer - Olimex A20-OLINUXINO-MICRO-4GB, The Olimex A20-Olinuxino-Micro single board computer is an extremely capable, small footprint device with a dual core CPU. Internally it has 1GB of DDR3 RAM, 2KB of EEPROM and a Mali 400 GPU, but it is its external connectivity that makes this board so special. The list of ports is extensive but the highlights are HDMI, SATA, Ethernet, 2 x USB plus 1 x USB-OTG, 160 GPIO pins, an LCD interface and an SD card slot. As you would expect many of the GPIO pins have additional specialist functions with interfaces for 2 x cameras (CSIO), UARTS, SPI, IR, touch panel, I2S, PWM, audio and more. In all departments it compares favourably to the Raspberry Pi with a faster CPU, hardware 3D acceleration and considerably more IO functionality. It can be made into a complete small footprint computer or kiosk computer with Linux, a hard disk, keyboard and mouse and HD display. Alternatively it could be used as the controller in an embedded system for robotics, photography, web serving etc.. This version has 4GB of NAND flash memory which comes with Android pre-loaded. A version is available without the NAND flash (73-0225).The board is released under the Creative Commons Attribution-Share Alike 3.0 United States License and as such it can be reproduced for commercial use. Please visit the Olimex website for full details. The associated software is released under the GPL licence. There are no software binary blobs on this system and the hardware design is fully documented and available online to copy or modify. In all, this is an ideal platform for exploring microcontroller connectivity or as the core for an Internet of Things product.
