The MiSTer FPGA Analog IO board v6.1 includes the following useful features a VGA (DB15) connector allowing for the output of a VGA/RGB/YPbPr signal depending on the cable being used, a 3.5mm audio jack with Mini-TOSLINK providing analog audio output and digital audio output, a secondary microSD card slot the functionality depends upon the core being used, a fan speed control providing a 3.3 volt / 5 volt selector jumper, a status LED control jumper allowing switching on or off the built in LEDs, a Sync-on-Green switch, three status LEDs (red, yellow, green), three large push buttons providing system reset, on screen display menu and game reset, an expansion connector in the form of a USB 3.0 connector however this is not for standard USB devices.

The MiSTer I/O Board v6.1 adds one additional GPIO pin to the User IO port, providing support for the Sega Mega Drive / Genesis / Master System game pads using a SNAC board.

Once assembled each MiSTer FPGA IO board is inspected under a microscope to ensure no solder bridges are present, the completed version 6.1 IO board is fully cleaned in an ultrasonic bath to remove any flux residue left over from assembly, once clean the IO board is fully tested on a live MiSTer setup. Each IO board uses high quality branded components including Samsung Electro-Mechanics and Bourns Inc.

Configuration of the video output signal on the IO board is controlled via the MiSTer.ini file, more information on how to configure and download of the MiSTer.ini file see the MiSTer.ini configuration page.

For more information on analog video output compatibility see the MiSTer wiki.

    As a new MiSTer owner having a great resource for parts in the UK is fantastic!

    I ordered this io board along with all the other bits and bobs I needed to fully set up my sandwich. Nat was super helpful and was very patient with me when I had a “rtfm” moment.

    I’ll be sure to come back and I’m already recommending the store to my potential MiSTer owning friends.

    Absolutely brilliant service. Item was listed as ‘available on back-order’ but don’t let this fool you into thinking there will be a long lead time, item was delivered within 5 days (this timeframe including a weekend) of clicking buy.

    Product is to an extremely high standard and I have no doubt it will outlast similar products from eBay sellers in China. Also this product contains all components, whereas some I have seen on eBay may be missing LEDs, or header pins which are easy to miss from images but can impact functionality. It may be a few £s more (and we are talking about a very small margin here) but you are receiving a fully populated, quality controlled product in the quickest timescales available for UK delivery.

    Great attention to detail, such as the measured and trimmed fan leads (rather than wrapping up excess wired with a ty-wrap).

    I’m an avid bargain hunter and always strive to get the best value for money in my purchases, it is my opinion that offers that for his products in the UK, only to be beaten if you want to build the board as a DIY project.

    Very well put together love the quality of the product and the service, thanks!

    Fantastic product and an essential purchase if you want to use the mt32-pi hat for the ao486 core. Nat is a pleasure to buy from and gives a 100% reliable service, fast dispatch and quality products with free uk postage, what are you waiting get an order in today.

    Picked this up with the other essentials to bring my DE-10 to life, it came tightly packaged ensuring everything arrived in good shape. The device itself is awesome, allowing me to extend the connectivity of my MiSTer setup. The lights letting me know when the drives are working, and whether the core has hung, are hugely useful. I’ve not fully explored the capabilities of the board yet but so far so good. Easy to assemble, perfectly packaged, perfect customer service, sorted.

  6. Cristian Vasilescu (verified owner)

    Use the board to power a brand new MiSTer with all the parts bought from Nathan. Power on first try and going strong. Highly recommend due to ease of communication, quality of products and packaging!

  7. Christoph Linden (verified owner)

    Great quality and great service. I got this primarily for the VGA and the analog audio out. I am planning to put it into my Bartop cabinet for Arcades. The shipment, the build quality and the service is just awesome. I needed to ask for one support question and got an immediate answer that also fixed the mistake I made in my setup. (yes, make sure you have the toggle switches setup correct 🙂 ).

    Thanks Nathan for this great support of the MiSTer community here in Europe.

    Beautifully put together and well packaged. The Noctua fan is so quiet; I didn’t even realise it was running!

  9. Baz (verified owner)

    Even though I already had an I/O daughterboard, mine didn’t include a couple of sockets and also wasn’t the XL version; meaning it was missing two screw holes. This meant I was always aware when pressing the buttons that the underside of the board might touch components on the main DE10. I decided to replace my board with one of Nathan’s and I have not been disappointed. The postage and packaging was great, the board arrived in perfect condition, great soldering work and finally I can secure it to my DE10 without worry. Great board. Highly Recommended.

  10. James Boothby (verified owner)

    I was so impressed with the 7 port hub I came back and ordered the IO board and RTC to finish my DE10 build off. Everything works as described, the build quality and soldering is amazing, highly recommended!

  11. Nadim Slim (verified owner)

    I got a Noctua version. The fan is super quiet I can not even hear it. The IO board is really well made, and it has all the extra connectors that could have been left out, but Nat put them all in. All in all great work, and the board looks really good in black.

  12. Per Gollubits

    Got the Noctua version. Clean assembly, looks and works great. I couldn’t have done it better myself.

  13. robibennobi (verified owner)

    Great board and extremely well put together. Love it and it looks killer in black!

  14. Mike May

    Another well made board from Nathan, actually ended up getting a pair of these, I went with Noctua fans for mine, look great in black too, this will have added uses for SNAC controller adapters that are becoming available in various ports example the SNES. But the main use is 240P and VGA output with optical / 3.5mm jack sound outputs.
