Hello. I recently bought a Digilent Arty FPGA dev board. I need to connect some 8-bit or 16-bit SRAM chips to the board and I have to determine what the best method would be, to bring out the ( 40, I believe ) data lines on the four 6x2-pin Pmod connectors on the side of the Arty and connect them to a solderless breadboard, preferably without any soldering involved in this process at all. I need access to the Arty's LEDs and buttons on the top so I don't really want to go with a stackable Arduino shield, which requires much soldering to attach a solderless breadboard, at least, soldering is required for the Arduino shields that I've seen. Well, after thinking about my problem and the requirements for the SRAM chips in my design, I thought of a way to easily connect my Arty to any old breadboard. I plan on buying a few Pmod extender cables, some Pmod 2x6 pin headers / gender-changers and some 12-pin Pmod to DIP adapters. I could plug two or three Pmod extension cables into my Arty, plug 6x2-pin DIP connectors onto the ends of the cables and then plug the cables into a breadboard of my choice. I've made up a list of things I'd need to buy from Digilent and I think that I need a few of these : http://store.digilentinc.com/2x6-pin-cable/ , this : http://store.digilentinc.com/2x6-pin-header-5-pack/ , a few of these : http://store.digilentinc.com/pmod-dip-dip-to-12-pin-pmod-adapter/ and finally just any solderless breadboard. I'm wondering if this is the easiest method with which one access all of the data GPIO lines exported by the FPGA via my Arty's Pmod connectors -- if I've missed something obvious or this question seems stupid, then please forgive me. Any suggestions or advice would be appreciated, Thanks, jdb2
Hi, a customers has question about how to secure the power terminal in the large breadboard we sell. (see below email). Hi, I ordered this item as part of a recent order: 424-BB-KIT-LARGE The item has a design flaw which means that the power terminal pins cannot be mounted onto the back board securely. To mount the power terminals one must align 2 washers on either side of the backboard. These washers have cut outs that match slots in the board hole. Unfortunaly because the back board is too thin these washers can never be mounted properly and the each power terminal wobbles even when aligned correctly and tightened appropriately. The fault would is obvious to anyone trying to assemble the item and it does seem disappointing that this board was clearly never tested before being sold to customers - unless of course the manufacturer has reduced the thickness of the backboard between pre-production samples and the production run. Here are instructions: 1) Take out the nut and washer from the power terminal 2) Insert the terminal into the hole on the board (e.g. the black one for the ground) 3) Put the washer back on the back of the board 4) Put the nut on top of the washer and fasten it. 5) Flip the board and fasten the top of the terminal
