/technologies/fpga-group/b/blog/posts/lattice-ice40up5k-evb-evaluation-board-outputing-audio-sine-waves-over-an-optical-s-pdif-interfaceIntroduction Quite a long way back, I was fortunate enough to win a shopping basket in a Project 14 competition and the main item I purchased with it was an evaluation board for a Lattice iCE40UP5K FPGA device. Here, finally, is an informal look at ten-USTelligent Community 12https://community.element14.com/technologies/fpga-group/b/blog/posts/lattice-ice40up5k-evb-evaluation-board-outputing-audio-sine-waves-over-an-optical-s-pdif-interfaceSun, 22 Mar 2026 23:31:03 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5106f1ec-c028-4e57-8089-cef080f64d4bkmikemoo0<p>Very cool.&nbsp; Glad that you got to use your Lattice Eval Board.&nbsp; It&#39;s always good to finally get to those things that have been on the Project List for a while.</p><img src="https://community.element14.com/aggbug?PostID=29598&AppID=19&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/fpga-group/b/blog/posts/lattice-ice40up5k-evb-evaluation-board-outputing-audio-sine-waves-over-an-optical-s-pdif-interfaceSat, 21 Mar 2026 20:33:59 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5106f1ec-c028-4e57-8089-cef080f64d4bDAB0<p>Nice post.</p><img src="https://community.element14.com/aggbug?PostID=29598&AppID=19&AppType=Weblog&ContentType=0" width="1" height="1">
