Astra Mini S Pro Firmware
Firmware List
| Firmware Version | Minimal SDK Version | Firmware change note |
|---|---|---|
| v2.0.03 | v2.5.5 | The first version that uses the UVC protocol |
Notes
- A major version of v2.x.x (major version 2) indicates firmware using the UVC protocol, which requires the Orbbec SDK v2.
A major version of v1.x.x (major version 1) indicates firmware using the OpenNI protocol, which requires either the OpenNI SDK or Orbbec SDK v1.

Upgrade Tool
Note: Upgrading on the Windows platform involves frequent uninstalling and reinstalling the OpenNI driver, which makes the process relatively cumbersome. We strongly recommend performing the upgrade on Linux or ARM platforms first, as the procedure is simpler and more efficient.
How to use Orbbec SDK v2
After upgrade OpenNI Protocol to UVC Protocol,switching to Orbbec SDK v2 for how to use SDK.

Gemini 435Le Firmware
Firmware List
| Firmware Version | Minimal SDK Version | Firmware change note |
|---|---|---|
| v1.3.11 | v2.5.5 | 1、Fixed the issue where the hardware trigger command was not effective. 2、Solved the anomaly that could cause the device to become unresponsive when enabling the hardware Depth-to-Color alignment function at 1280×800 resolution. 3、In Dimensioning mode, the default precision unit has been adjusted to 1mm. 4、Adjusted the frame ID counting logic for the RGB image, with the default initial value now set to 1. 5、Added the RGB ROI target brightness setting function, allowing users to specify the target brightness within a region. 5、Optimized the network IP configuration process and DHCP logic. |
| v1.3.6 | v2.4.11 | 1、Fixed an occasional issue of timestamp deviation in multi-camera synchronization. 2、Added support for independently adjusting the disparity offset value under different resolutions. Users can flexibly configure different working distances for the cameras by setting different offsets. 3、Fixed an issue where confidence data was lost when depth data was missing. 4、Completed the metadata information for the RGB MJPEG stream. 5、Optimized the IP configuration process: IP settings now take effect immediately without requiring a restart; added a Force IP feature; enhanced network fault tolerance—automatically switches to static IP mode when DHCP assignment fails. |
| v1.3.2 | v2.4.8 | 1、First Official Firmware Version. 2、Improve the depth effect of AMR Perception & Dimensioning mode. 3、Add a new feature to adjust the minimum working distance by configuring an offset. 4、Add a new feature to support dynamic adjustment of confidence thresholds and enable retrieval of depth confidence maps. 5、Enhance firmware stability. 【Caution】If the device firmware is older than V1.3.2, you must upgrade to V1.3.2 to ensure design image performance and user experience. |
