Creating a custom board and program it

[Raja]

I have used Arduino for some time and i am very new to NRF. So i am struggling with any thing i do. But i am really motivated to learn it.

Completed setup for eclipse to program nrf51. Purchased NRF51 DK, it is great. I can program it and use it.

But as a next step i would like to create a custom pcb design using nrf51/nrf52, which will host 2 buttons, 4 leds, temprature sensor and a accelerometer. It may seem too many components. I can just start with a button and led to make it simple.

But i do not know where to start from, for arduino i have used Eagle/KiCad before. I used to program the chip using isp programmed then solder it in board. Also i use to define all pins in the main arduino file.

How should i start with Nrf, do i need to program chip before? Can i program it after it is soldered. How to define pins? Or i can just program it wireless.

Till not i found this article: devzone.nordicsemi.com/.../

@Rahul: I'm not sure if I understand what you want, but you won't be able to plug a bare nRF5 device into a breadboard and assemble an antenna, etc. in the breadboard as well. The antenna needs to be almost perfectly tuned with the correct capacitor values etc. to work and the "rails" in a breadboard is loaded with stray capacitances and whatnot. You will need an nRF5 breakout board with an assembled antenna on it so then why not use your dev kit.
