Where can I get my hands on a Maple Native?

I am working on a research project where we are using a Maple-powered embedded system. However, we have an issue where the Maple does not have DAC. I did notice that the Maple Native does have its own DAC, which would be very valuable to this project?

Is there any way I can get my hands on a Maple Native?

BlackBelt2025 - what digital to analogue conversion rate is required?
I'm asking in case you can't get a Maple Native as there may be other solutions.

Our target rate is 100kHz for our entire program.

Basically, we do 4 analog reads (using the dual simultaneous sampling), do some simple calculations, and output a single analog signal.

We know that we can get an external DAC chip, but my professor would really like to keep everything as integrated on the board as possible.

If you can't find a Maple native and it has to be on one chip/board and libmaple/wirish compatible, there is the possibility to build an Orone Mini, equipped with an STM32F303Cx.

You'll get the desired two-channel DAC and a lot of other goodies(2x dual-ADC, floating point unit, ...)
