This SparkFun version adds a Qwiic connector for easy I2C sensor and actuator integration. It can be programmed using entirely open-source tools via Project IceStorm.\n\nThe Cu provides 79 I/O pins, eight general-purpose LEDs, and a 100MHz on-board clock that can be manipulated internally by the FPGA. A USB-C connector handles configuration, power, and serial data transfer. Like all Alchitry boards, it supports Lucid HDL and includes a built-in component library and debugger.\n\nKey Features\n\n\nLattice iCE40 HX – 7,680 logic cells\n\n79 I/O Pins – For connecting external circuits\n\nQwiic Connector – I2C integration with the Qwiic ecosystem\n\n100MHz Clock – On-board, internally configurable\n\nUSB-C – Configuration, power, and serial data transfer\n\n8 General Purpose LEDs – For status and debugging\n\nOpen Source Toolchain – Supported by Project IceStorm\n\nLucid HDL Support – Built-in library and debugger\n\nExpandable – Stackable Element boards for added functionality\n\n\nCompatible Element Boards\n\n\nAlchitry Io Element Board – LEDs, buttons, and DIP switches\n\nAlchitry Br Prototype Element Board – Prototyping space\n\nAlchitry Ft Element Board – High-speed FTDI interface\n\n\nIdeal For\n\nGetting started with FPGA development on a budget\nLearning digital logic with open-source tools\nI2C sensor integration via Qwiic\nSTEM education and coursework\n\n\nPackage Contents\n\n1× Alchitry Cu FPGA Development Board (with Qwiic connector)\n\n\n\nTip: For more logic capacity, see the Alchitry Au (33k cells) or Alchitry Au+ (100k cells).\n\n\nResources\n\nProject IceStorm (Open Source Toolchain)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3966,"title":"Default Title","sku":"SF-DEV-16526","price":125.43,"on_sale":false,"in_stock":true,"available_quantity":31,"option1":"Default Title"}]}
