Hi DanKa,

Yes, the nRF52-DK is used as a DK for both nRF52832 and nRF52810. There is a user guide in the SDK (v14.1.0 and onwards) on how to use the nRF52-DK to develop for the nRF52810, see this link.

Best regards,

Andreas

Hello and thanks for your answer.

The nRF52810 Looks interesting. Do you simply recommend the nRF52-DK for developing the nRF52810? I will order both: nRF51-DK and nRF52-DK. Since the nRF52-DK uses a nRF52832, can I restrict the board to simulate the nRF52810?

Kind regards

Hi DanKa,

The nRF51822 is not deprecated, it is still in production and probably will be for quite some time still. We do not have a habit of EOL-ing our devices as you can see from our product pages, some devices have been available for a long time and still are.

You should be aware though that while still a fine device, the nRF51 series is a generation older than our nRF52 series and e.g. does not support some of the features in Bluetooth 5.

If nRF51822-QFAB is suitable or not for using with the S130 depends the flash/RAM requirements of you rapplication. You might be able to squeeze a very simple application in, but maybe not as central. The nRF51-DK has the QFAC chip so you will know when you have finished developing and optimizing if you can go with the QFAB or need the QFAA. Some margin can possibly be gained by using an older SD/SDK.

The hot tip from me though is to actually consider the nRF52810. You will get the latest features and the best performance. The pricing should not be too different, but you should contact your distributor for this.

Best regards,

Andreas
