lost antenna and nrf51822 samples

vicky72

Hi,

I have ordered nrf51822 development kit with one of my local vendor. when the product came to india , it was checked in customs office somehow the samples in the kit and antenna got lost. can somebody help me finding the part number for

  1. Helical monopole SMA antenna
  2. nRF51822 chip samples

so that i can ask my supplier to place another order for this? if possible please let me know the site from where it can be ordered?

Note: I have checked mouser but could not find the antenna and for nRF51822 chip samples there are many like nRF51822-QFAA-R7, nRF51822-QFAA-T, nRF51822-QFAB-R, nRF51822-QFAB-T.

Please help me finding these.

    I don't know the legal issues in India but hopefully you could apply for a partial refund at the post office. As for the antenna, any 50 Ohm 2.4Ghz SMA antenna should work. You can search through eBay for really cheap ones.

    For chip samples, take the QFAA for development (256kB of ROM, QFAB has 128kB of ROM for less complex applications). You are ordering only a few of them so it really does not matter if you buy R7, R or T. R7 means 7'' reel, R is 13'' reel, T is tray. This is important for manufacturers to order a correct packaging option which can be used in their pick&place machines.

    Best, Marek.

    Though keep in mind that until recently (no idea if it's changed) Mouser was still shipping the G0 version of NRF51822 which isn't guaranteed to work with the recent soft devices. Perhaps it's safer to deal directly with a local distributor for Nordic.

    @Janek , I have taken part numbers from mouser as reference. I am dealing with my local vendor only. But the local vendor gets product from some other vendor like mouser so it takes so much time and i need to explain them exactly to get things. And thanks for the info.
