how to programme the nrf51 chip without using the development board

[Tiger]

Hello , I have been testing some programmes on the nrf51 chip which is on the development board . However now I'm looking into programming multiple nrf51 chips so how can I do so ?

To program to chip, you just have to power it, connect swio/swclk pins to SWD programmer (like jlink), and... flash it.
