There is a need for simple devboards. NXP's Dev board is over-featured and not generic enough. ST seems to get it, literally every subfamily has a nuclio board. And the embedded artists board is (1) EXPENSIVE (I don't even know if I'm interested, but she wants a ring), (2), the carrier board at least, irritating to interface. The teensy formula is a winner here, other than JTAG/SWD they have the best form factor.
Agreed. Nucleo boards are great for that. No gadgets, cheap, and most IOs broken out. As I remember, TI did something similar with their MSP430 and MSP432 MCUs.
Teensy boards are almost that, but most of them have very few IOs broken out... The Teensy 4.1 has more and is great, but still, that's few IOs.
Buf when we say "there is a need", is this significant enough that vendors would bother? A few of us want boards like this, but I have witnessed countless times that even seasoned engineers tend to favor fancy boards with a lot of buttons and displays even when they actually don't need them or will use something completely different in the end. I dunno. Maybe it's just the kid that's still within us. Another factor is that engineers buying dev boards in the context of their employed jobs will tend to favor expensive stuff, as long as their management is OK with that, because it's not their own money. Conversely, engineers buying cheap devopment tools, even if those are perfectly fit for what they need, may sometimes face their management's opinion, like "are you sure? a $20 dev board? must be a toy!"
