Do I need a Jtag cable to program and debug nRF51 dev boards ?

[cybero]

Hi all,

I would like to know how can I program and debug the nRF51822 development boards? I've seen some boards have a built-in programmer and others haven't.

How can I know if the board I want to buy need a JTAG ?

For example, does this cheap board need a JTAG to program it ?

Thank you.

That board does not have a built-in programmer or debugger. So yes, you will need a separate JTAG/SWD device in order to program the nRF51822.

I agree with JohnBrown answer. It's better to buy a new DK which works as both the development board and a programmer/debugger.

@cybero: If you think the answer from John is valid, could you accept it ?
