I´m totally aware about pythons overhead but it´s required for my project. As I saw for the ADC DAC board it states that with python 12ksps would be possible. Those boards are comparable, or am I misstaking?

I did some basic testing of sampling one channel with 512 samples and timed it. If I break it down to one sample it results in ~21ksps.

Just wanted to double check if some experienced simimlar performance or can give me some guidance.

Thanks & greetings
