I'd like to know what dev kits i should order;

[Andrew Frazer]

Hi,

I'm wanting to develop some solutions around the NRF518222 IC. I want to try out the various modes etc, bluetooth and ANT as well as trying to get some longer range serial data links going.

I'm just a little confused as to which Dev kits i should buy..

(1) Is the NRF51822-MKIT the same thing as the NRF51822-EK, except that the EK has two boards, and not one?

(2) What does the Start Kit NRFGO ( NRF6700 ) + Dev Kit give me over the evaluation kit

(3) What is the difference between the NRF51422 and the NRF51822

I could just order them all, but someone might be able to point me in the right direction!

Hi,

Since you want to develop with both Bluetooth LE and ANT, there is only one chip that can do this, and that is the nRF51422. The nRF51422 a bit more expensive than the nRF51822, since it supports the ANT protocol, made and licensed by Dynastream.

Dynastream opened up for having the ANT softdevices as binaries, which means that the nRF51422 can actually be loaded with any of our Softdevices (S1x0/S2x0/S3x0).

The development kit requires that you have a nRFgo Starter kit, which will then be a more expensive kit if you're not planning to do development with the nRF24-series as well. Both the ev-kit and dev-kit has programmers, master emulator dongle, etc. However, the ev-kit is a all-in-one-package, where the debugger is on the same board as the nRF-chip, but it has only 2 LEDs and 2 Buttons (compared to 8 on the motherboard.)

I would recommend you to go with a new revision of the nRF51422 evaluation kit (v3.0.0 of the PCA10003 which has chip revision E0).

Best regards Håkon

Please also see this question for information on the difference between the Development and Evaluation Kits: https://devzone.nordicsemi.com/index.php/what-s-the-difference-between-nrf51822-evaluation-and-development-kits It's written for the nRF51822, but the difference is the same for the nRF51422 kits.
