Programming pins of the nRF51822 chip ?

[Berk Soysal]

Hello everyone,

Could anyone tell me which pins are the programming pins of the nRF51822 chip for a QFN48 packet ? How can I program it on my custom PCB?

thanks..

RedBearLab's MK-20 dongle is also a cheap alternative to programming custom boards isn't it?

Well, I am using MK-20 dongle to program bare nRF51822 chips with mbed the same way as if you have original readbear nano attached. No problem. Didn't use with debugger the same way like your J-Link, though.
