Meet Cora, Our Newest Product Line!

今天是我们令人兴奋的一天。

我们正在宣布新产品线的开始，Cora.

In 2007, we released our first Cmod(CarrierModule), introducing a small form factor product that could be breadboarded.

In 2012, we released our first maker-specific product line with chipKIT. These products had Arduino headers, mounting holes and robust power supplies. A few years later, in 2015, we introduced Arty, a maker/hobbyist FPGA product line that was 2.5 times larger, and combined high speed peripherals with additional Pmod ports.

在进入市场的第一年内，我们开始从客户接受反馈，虽然他们享受了arty的特点......他们感到arty更接近我们的更大，数字系统板（如巴斯迪，Nexys和Genesys）。对某些东西有兴趣可以更容易地借给原型设计，如CMOD，但这小于我们的微控制器产品（以前称为Chipkit）的arty和更接近。

After listening to this feedback, we developed Cora. Targeted at makers and hobbyists, Cora is cost-optimized and in a smaller form factor that is friendlier to prototyping.

Cora比arty Z7小50％，只比Wi-Fire板略大。

与微控制器产品线一样，有安装孔，我们已经使丝网印刷相同。像arty一样，Cora系列具有Arduino Chipkit标题和至少两个PMOD标头。

One unique characteristic of Cora is the unpopulated I/O header pins. Unlike a Cmod (where unused I/O are not accessible) or a Basys board (the I/O pins are entirely pre-assigned and cannot be re-routed) Cora allows users to solder their own headers to access additional I/O outside of the provided expansion headers that the FPGA/Processor is capable of.

The first board in the new Cora family is the科拉Z7!

Cora Z7是在Xilinx强大的Zynq 7000系列中建造的。Zynq技术是一个A二P罗布布布尔SystemonC将臂处理器与Xilinx 7系列FPGA相结合的臀部（APSOC）（思考Rasbperry PI和ARTY A7板在一起）。这种组合允许硬件设计人员访问软件资源（如Linux和开源工具）和软件设计人员以访问硬件配置（例如，如果需要进行自定义接口或更多特定通信端口所需的话）。

The Cora Z7 comes in two varieties, a single core Z7-07S and a dual core Z7-10. Both versions of the board are identical except for the location where the Zynq chip is loaded. In-depth specifications for the Cora Z7 are listed below:

• ZYNQ Processor
  • 667MHz双核或单核Cortex-A9处理器（取决于哪些变体）
  • DDR3 memory controller with 8 DMA channels and 4 High Performance AXI3 Slave ports
  • High-bandwidth peripheral controllers: 1G Ethernet, USB 2.0, SDIO
  • 低带宽外围控制器：SPI，UART，CAN，I2C
  • Programmable from JTAG and microSD card
  • Programmable logic equivalent to Artix-7 FPGA
