40 × 30 3D depth module combining a hybrid-stacked SPAD array and 940 nm VCSEL for 0.2-8 m ranging at 30 klux, with USB-C/FPC interfaces and point-cloud, depth and confidence outputs.
Key Highlights
The DOMI DMAS2M001 is a compact dToF array module that combines a hybrid-stacked Single-Photon Avalanche Diode (SPAD) sensor with a 940 nm VCSEL illuminator. It delivers 40 × 30 depth data at 10 fps across a 60° horizontal × 45° vertical field of view.
The published ranging specification is 0.2-8 m for targets from 10% to 90% reflectivity at 30 klux. Accuracy is specified by distance band: ±2 cm or better from 0.2-1 m, ±3 cm or better from 1-3 m, and 1% or better from 3-8 m. These conditions make the module a candidate for compact robotic perception, UAV ranging and other embedded 3D sensing designs that must operate beyond controlled indoor lighting.
Selection note: the published range and accuracy values are module-level specifications under stated conditions. Final performance depends on the target, optical window, contamination, motion, ambient light, temperature, host configuration and mechanical integration.
DMAS2M001 is designed for compact equipment that needs spatial depth rather than a single distance value. The following applications are based on uses named in the datasheet; system performance must be validated in the intended scene.

FAE accuracy note: the datasheet presents range and accuracy values but does not provide a complete test procedure, confidence threshold, frame-averaging setting, target geometry, motion condition or temperature point. Confirm the current acceptance test and firmware configuration before design freeze.
Yes. DMAS2M001 uses a hybrid-stacked SPAD receiver and a 940 nm VCSEL light source for direct Time-of-Flight depth sensing.
Yes. The datasheet specifies a 0.2-8 m distance range for targets from 10% to 90% reflectivity at 30 klux. Final range must be validated with the actual target, cover window, contamination, motion and temperature conditions.
Yes. The published error limits are ±2 cm or better from 0.2-1 m, ±3 cm or better from 1-3 m, and 1% or better from 3-8 m. Confirm the current production test method before design freeze.
Yes. The datasheet lists point-cloud, depth and confidence outputs. It also lists UDP and UVC protocols; confirm which streams and formats are available on the selected interface and firmware.
Yes. USB-C and FPC are both listed as interface options. Request the current connector drawing, pinout, electrical definition and supported protocol mode for the configuration you intend to purchase.
Yes. The datasheet lists SDK support for Windows, ARM and Linux. Confirm current operating-system versions, toolchain requirements, drivers, APIs and redistribution terms for your project.
Yes. The module datasheet identifies the eye-safety classification as Class 1. The finished product still requires laser-safety assessment after the module is installed behind the final window, enclosure and control electronics.
Yes. The cased module is specified at 35.5 × 25 × 16 mm, 7 g and approximately 1 W power consumption, with a 5 V / 1 A supply requirement. System designers should still budget for startup, peak current and thermal conditions.
Yes. UAV altitude determination and leveling, navigation obstacle avoidance, autofocus assistance and security monitoring are applications named in the datasheet. Qualification in the intended environment is required before production use.
