confusion re. TF mini

looking at the data sheet for the TF midi I’m confused about setting the baud rate. H1,H2 H3 H4. What would these look like if I wanted to change the baud rate to 9600 baud?

Which TF Mini?

Sparkfun has like 4 of them.

There is example code for setting the baud rate here: https://github.com/TFmini/TFminiPlus-Ar … aud_EN.ino

*disclaimer, I haven’t tried it
