The Alchitry Cu is an affordable FPGA development board featuring the Lattice iCE40 HX with 7,680 logic cells. 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.
The 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.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
