nRF52832 development tools

[JS]

What development kit should I buy? Is this the right one? www.mouser.hk/.../

What software IDE to use?

1. Does Keil offer free version for limited code size? What is the size limit?

2. Which tools is free and un-limited code size?

3. How is mbed? I have used mbed for simple test with STM32 Nucleo. Is this similar?

1. 32kB - not as useful as it used to be these days.
2. some: gcc + makefiles some people use, you can use Eclipse with a bit of setup work, Segger has Segger Embedded Studio which is free for non-commercial work, that's a rebranded version of Crossworks (which isn't free but isn't expensive for non-commercial work). Nordic provides examples in keil or native gcc (makefile) format. It's not that much work to import those into SES/Crossworks
3. I never liked MBED at all and there are fewer examples which use it. I'd try to work at with the SDK native code and one of those tools if possible.

Hi RK, Many thanks. May I ask if 32kB limit starts counting excluding factory provided stack and various devices managers. Are these binary and not C and not counted? Is 32kB only counts my self-written test code?
