nRF51922 DK

[Quantum Dimension]

Hello,

Where do we buy the nRF51922 DK / EK kits? I do not see any purchase links online.

Also, how flexible is the ARM core for programming ?

Thank you!

Thank you very much for the reply. I have contacted the distributors for our region as advised.

I see that the part has a receive sensitivity of about -90dBm for Ant and -93dBm for Bluetooth signals. I understand antenna design, orientation etc can affect the performance. But is it possible to augment to the RF performance outside the SoC ? Is it recommended? Please let me know.

Thank you!

-90dBm is ~1 pico Watt and -93dBM is ~0.5 pico Watt if my brain is working properly today. I would think that the noise floor would be such that it would be hard to keep all factors equal (transmission power, receiver sensitivity, encoding, bandwidth, bit rate) and achieve much better performance.

Maybe you could refactor your question -- what are you looking to achieve?

My old boss teach me 25 years ago: The best amplifier is a good antenna. -93dBm for Bluetooth signals, but what about blocking?
