recommend a development kit with 3 independent DAC outputs exposed ?

Hello Everyone,

 

I would like to get recommendations for STM32 development kits that have at least 3 DACs with their 3 independent outputs exposed, preferably a newer kit that can run an RTOS (not Linux). The faster the better.

 

Thank you!

I assume I cannot "Accept as Solution" but one of the answers above. But, both @TDK  and @MasterT  had answers I wanted and was looking for and am most grateful for.  I have purchased both boards and will try the newer/faster one first (NUCLEO-H7A3ZI-Q) and see if it will do what I need. If not, I'll fall back to the other one (nucleo-G474re).

@Andrew Neil : If I just counted on AI, I'd still want verification from an experienced person. Still, the AI has been helpful for injecting new ideas. Thanks!

 

Thanks!

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

NUCLEO-H7A3ZI-Q has independent DAC outputs on PA4-PA6 which are all exposed. Two outputs are on DAC1 but they are independent.

I don't think any STM32 chips have 3+ DACs that all support external output, but if you just want independent outputs, the above will work, among others.

nucleo-G474re has 2 regular buffered dacs, than +4 fast 15 msps buffered by internal opa's. Total 6.

Not sure it can run RTOS
