@Noah-Heinen , unfortunately it is not possible to add a TOF sensor to your current Voxl2 Mini configuration. M0188 adapter does not support TOF.
The only way this would be possible is:
remove M0188 add M0172 and connect TOF and either M0186 or M0166 camera add another M0172 or M0194 and plug in a single camera. Unfortunately right now we don't have a small adapter like M0172 or M0194 that supports two standard cameras like M0166 or M0186.So you would probably be losing one of the tracking cameras if you want to add a TOF sensor.
