https://devzone.nordicsemi.com/f/nordic-q-a/13732/what-is-the-difference-between-nrf52-dk-and-nrf51-dkI want to purchase a BLE development kit. My current preference is nRF51 because there are more nRF51422 BLE modules in the market. www.nordicsemi.com/.../3rd-Party-Bluetooth-Smart-Modules I would like to run ble_app_uart on the BLE chip.

That is a valid point I guess, but it probably won&#39;t take long before we see lots of nRF52 based modules too.</p> <p>Although I might be a bit biased, I would definitely go for the nRF52 DK. It has a lot more features (hardware PWM, PDM, I2S, NFC, ++), it has a faster and more advanced CPU, and it is more power efficient. And even though it is a kit with more features it is currently sold on mouser.com for the exact same price as nRF51 (at least in my area).</p> <p>We have also strived to make it easy to port code back and forth between nRF51 and nRF52. So no matter what kit you end up with, it shouldn&#39;t be that hard to migrate to the other.</p><div style="clear:both;"></div>
