 The Zybo board is a powerful low-cost SoC development board. It is based on a powerful Z-7010 chip from the Xilinx Zynq-7000 family and contains many interfaces like audio, Ethernet and USB. The Z-7010 chip also contains a dual ARM Cortex-A9 which makes it easily possible to run an embedded Linux from an SD card. Moreover, six P-mod connectors allow access to the FPGA, the processing system and the internal ADC. Additionally, many different P‑mod modules can be found at the [Digilent Store](http://store.digilentinc.com/pmod-peripheral-modules/). For more features and detailed descriptions see the [Zybo Resource Center](https://reference.digilentinc.com/zybo/zybo). A further reason for selecting the Zybo was the documentation with tutorials and example implementations. They, too, can be found at the [Zybo Resource Center](https://reference.digilentinc.com/zybo/zybo). To sum up, the Zybo is a solid and well-documented and supported SoC development board for beginners.
