Can I get any ARM microcontroller dev board and its JTAG programmer <$40

[sangar]

Hi,

I am looking for ARM MCU dev board and its JTAG programmer and expecting them to cost me under $40...Please suggest if you came across them...


Thanks,
Muthu

Any ST Discovery or Nucleo board. They both include snap-off ST-Link for debugging.

Also, see this discussion (not all of the boards mentioned include debug interfaces.  But many do...): https://www.eevblog.com/forum/microcontrollers/list-of-cheap-arm-development-boards/

Silicon labs Dev boards have built in segger j-link which can be used internally or with external device. Price eur 30+

I am a big fan of the ST-Nucleo boards. They all have builtin ST-LINK/V2 and most are $15 or less. They come in 3 (or more) different sizes mainly depending on which MCU you choose. The pinouts are subset and superset of Arduino. Great way to evaluate any ST MCU.

+you can use Seggers official tool to reflash ST-Link to become a J-link (and can be reversed using the same tool).

The limitations are that you are allowed to flash that stuff only onto a development board, only to use with STM32's (haven't actually tried if it even works with other brands' chips), and can't use it in production. None of there seem to be a problem for you, and J-link offers much better performance over ST-link.

Actually, you can get NUCLEO-H743ZI board for about 20-25€, and H743 is the most powerful ARM microcontroller on the market (400MHz CM7 with double precision FPU 1Mbyte RAM, 2Mbyte flash, shitload of everything you'll need and another 2 shitloads of stuff you'll probably never need )

I tried with Atmel SAMD and it didn't work. Ended up buying a j-link clone for $15 or so.
