MR60BHA1 vs MR60BHA2 — access to raw/low-level data for respiration research

Hello Seeed team,

I’m conducting research on using mmWave radar to detect breathing rate. After working with the MR24BSD1, I’m considering upgrading to either the MR60BHA1 or MR60BHA2. From the forum posts and wiki, I noticed some feature differences between these two modules.

Could you please clarify which module supports capturing raw data or original data (e.g., raw ADC samples or minimally processed data)?
Any pointers to documentation or example code would also be appreciated.

Thank you!
