What is the difference between nRF52 DK and nRF51 DK?

[helpme]

I 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. Does it matter whether nRF52 DK and nRF51 DK is used for ble_app_uart?

What are the differences to consider between nRF52 DK and nRF51DK when making a purchase?

Hi,

The ble_app_uart example will work perfectly on both kits.

"...because there are more nRF51422 BLE modules in the market". That is a valid point I guess, but it probably won't take long before we see lots of nRF52 based modules too.

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).

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't be that hard to migrate to the other.
