Introducing the Lattice iCEstick

iCEStick Evaluation Kit: Rapid Development for Affordable Innovation

USB thumb drive form factor evaluation board - The iCEstick Evaluation Kit is an easy to use, small size board that allows rapid prototyping of system functions at a very low cost using Lattice Semiconductor's iCE40 FPGA family.

IrDA and Digilent Pmod™ interfaces - Users can communicate to an IrDA transceiver, a Digilent Pmod™ peripheral connector for various sensor expansion options, 16 generic I/Os and LEDs.

Development Software - The iCEstick Evaluation board is supported by Lattice iCEcube2™ design software for HDL development. Programing the onboard iCE40HX-1k device's SPI flash is done with Lattice Diamond Programmer.*

*Lattice Diamond Programmer version 2.2 requires an additional software patch that can be downloaded via the downloads tab below. Version 3.0 or higher does not require a patch.

IrDA Tx & Rx Reference Design

  • Designers can use the included reference design to simplify the prototyping of a wide variety of applications involving wireless transmission of data or control signals utilizing the onboard IrDA transceiver. Examples include wireless data transmission between two mobile devices such as smartphones, tablets, gaming devices, etc. Wireless control applications such as high end remote controls, TVs, LED lighting control and others can also be implemented.

iCEstick with Pmod™

  • iCEstick contains a Digilent Pmod™ connector to attach various peripheral modules. The accelerometer reference design using Pmod™-ACL is an example. Purchased separately, this HDL design showcases how the iCE40 device interfaces to an acceleromter sensor, enabling the user to integrate additional sensors for their particular product.
