I need a small size Nucleo board that can handle datatype double - What board?

Hi!

I need a small size Nucleo board that can handle datatype double. I have seen that Nucleo 144 can handle doubles, but can Nucleo 64 boards handle datatype double as well?

Double precision FPU to be precise.

FPU-D found in F767, H743 and H745

If you need small, consider a Flight Controller board. H750?

All the STM32 can do double math, just in software, the ARM FPU-D isn't as exotic as the Intel/Motorola parts of yore, still needs some sw to do transcendentals.

Basically, every Cortex M MCU can handle the double data type - with proper emulation code that comes with the toolchain.

Some bigger one's - as Clive Two.Zero suggested, have an FPU supporting double directly. But no trigonometric functions.

The first board Clive references is a really nice little board but finding the schematic for it is difficult. I eventually found a vendor who located it for me
