adaptor for nrfgo j-link lite??

Scott

I'm trying my best to get started w/ the nrfgo 51822 development kit that I got last summer, but I'm just having a hard time jumping in.

I was a little disappointed to purchase the kit only to find out that I needed to spend another $400 for the nrfgo platform (which for some reason wasn't clear to me, even though I've implemented about a dozen different development kits over the last decade, and taught them to so many students). In any case, I thought I'd just move on from my stupid mistake, using just the J-link lite, the USB dongle, and the SDK the kit unlocked for me -- which are worth about the price of the kit I can't use, if not more.

So, now I have an nrf5822 module on a breakout board that I assumed would be usable, and I go to plug in my nrfgo-supplied j-link lite (I know, not quite kosher, but I think in the spirit of the license agreement - especially if I tape the nrfgo board to my board!!), and I notice the teeny tiny little connector on the supplied J-link lite.

Can anyone tell me where to get an adaptor to break that sucker out to a conventional 0.1" connector?

Honestly, the product line looks fantastic, but breaking into the DK's has been problematic for me. I'm pleased to see the nrfgo kit is no longer "recommended", but I'm still stuck. It's not the money that keeps me from laying out for a new kit, but the time. I'd really like to get some code downloaded to this chip and set up my dev environment ASAP. I set aside a bit of time for it, and it's going away fast.

    It was pretty clear the old dev kit needed Nordic's standard base kit to make it work. Nordic certainly highlighted it on the site at the time. It made sense then as all their dev modules plugged into it, of course the most recent kits don't even need that any more.

    You have a couple of options over and above building your own complete nrf51822 board. One is just to power up the board you have, there's a few questions here about how to do that. Another is to buy one of the relatively cheap 3rd party mounting boards which has switches and leds on it. mommosoft makes one which has a USB/UART connection, 8 switches, 8 LEDs, power and some breakout connectors, there are probably others, price not radically different from that Segger cable and no messing about. Or you can build your own one of those if you just want power and LEDs, the connectors on the DK are standard, and plug the board into it.

    Thanks -- though poking around, it seems I'm not the only one who made this mistake. I did see the note about nrfgo being needed, and poked around for about 20 minutes trying to figure out what was meant by that, and eventually arriving at the wrong conclusion. In any case, how "highlighted" the need was is mooted now, with the new dev kits.
