Great little chip for driving up to 8 7-segment displays at a time, and fully daisy-chainable. There's nothing special about the 'circuit', it's more of a display-specific breakout board. The annoying bit for me is that each display package seems to have its own unique pinout - there's no real standard. I have a feeling I'll be respinning that board to split the outputs into rows and columns, along with a few sub-boards to individually break that out for various packages.<br><br>-Wayne<br><hr id="zwchr"><b>From: </b>"geneb" <geneb@deltasoft.com><br><b>To: </b>"Simulator Cockpit Builder's List" <simpits-tech@simpits.org><br><b>Sent: </b>Tuesday, July 23, 2013 7:21:56 PM<br><b>Subject: </b>Re: [simpits-tech] Help, I'm broke!<br><br>On Wed, 24 Jul 2013, Roy Coates wrote:<br><br>> Yeah, that's the one.
