This quick guide assumes you are familiar with doing PCB designs in EAGLE, otheren-USTelligent Community 13https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nrf5-and-cadsoft-eagle-rTue, 13 Sep 2016 09:05:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3c4e09c1-d966-4eea-9d72-45272feec762&#216;ystein Smith0<p>I will look into creating a complete design for nRF51, I can&#39;t make any promises as of when it will fit in my schedule.</p> <p>Regarding the internal ldo vs. dcdc see <a href="https://devzone.nordicsemi.com/question/44333/internal-dcdc-vs-ldo-for-nrf52-series/">this question</a>, basically if you have the room on your pcb to place the external components required to use the dcdc converter you should place them, this does not exlude you from using the internal ldo. (Hence marking the layout without those components as not reccomended)</p> <p>I see that this was not clear at all from my text, I will rewrite that section.</p> <img src="https://devzone.nordicsemi.com/aggbug?PostID=960&AppID=4&AppType=Weblog&ContentType=0" width="1" height="1">https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nrf5-and-cadsoft-eagle-rWed, 07 Sep 2016 18:17:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3c4e09c1-d966-4eea-9d72-45272feec762energy0<p>Thanks for the reference design. It would be great to have a complete ref design with antenna for the nrf518222 (as you did for nRF52832). Why internal ldo is not recommanded ?
