Things to check before you put it on a quadcopter:

  • ZED Mini: It has a rolling shutter and connects over USB 3.0 Type-C. No IP rating is listed for it in the catalog. Its operating range is 0 °C to 45 °C. stereolabs... +1stereolabs.com ↗“camera.interface=USB 3.0 Type-C, camera.shutter_type=Rolling shutter”stereolabs.com ↗“thermal.max_operating_temp_c=45 °C, thermal.min_operating_temp_c=0 °C”
  • ZED X Mini: It weighs 88 g more (calculated: 151 g − 62.9 g), but it has a global shutter and runs at 60 fps. It is rated IP67 and works from -20 °C to 60 °C. It needs a GMSL2 / FAKRA Z connection rather than USB. On a fast or vibrating airframe, a global shutter may give you cleaner depth, so it could be worth the extra weight if your payload budget allows. stereolabs... +2stereolabs.com ↗“camera.interface=GMSL2 / FAKRA Z, camera.shutter_type=Global shutter”stereolabs.com ↗“mechanical.ip_rating=IP67”stereolabs.com ↗“thermal.max_operating_temp_c=60 °C, thermal.min_operating_temp_c=-20 °C”
