Key features

All-in-One Processing: The DM3602 chip combines ToF sensing, advanced signal processing (via an on-chip ISP engine), and application algorithm execution within a single unit.

Cortex-M3 Core: At its heart, the module features a powerful Cortex-M3 core. This is the component that provides the "computing power" you mentioned, taking over after initial signal processing to run

Reduced Host Load: By processing raw data internally, it significantly reduces the computational burden on the host processor, simplifying system integration.

Leveraging its on-board computing power, the module goes beyond simple distance measurement to offer a suite of sophisticated features right out of the box.

Integrated Algorithms: It natively supports algorithms for range finding, multi-zone human sensing, posture monitoring, gesture control, and keystone correction.

Smart Sensing: These built-in capabilities make it ideal for creating intelligent IoT devices that can understand their environment, such as detecting human presence in specific zones or recognizing s

AI-Powered supplier vetting

SummaryThe supplier develops and manufactures laser measurement chips, laser measurement modules, and laser wind radar products. It reports ISO 9000 and ISO 9001 certifications, 3D software design, ODM, broad customization, raw-material traceability, and 100% finished-product inspection. R&D staffing is reported at 6–10 engineers, with new products launched during the past year. Production-related evidence is mixed: reported lead time is within 15 workdays in both peak and off-peak periods, but the supplier states it has no inventory service capability and no overseas warehouse, agents, branches, or showrooms. After-sales procedures and corrective-action procedures exist but lack written records. Financial credibility cannot be positively assessed because the provided financial fields show zero operating revenue and zero profit-related figures for the reported periods. No customer cases or named customer references are provided.

Supplier typeThe supplier is a manufacturer and R&D-oriented provider of laser measurement chips, laser measurement modules, and laser wind radar. Its stated product description, factory location, R&D staffing, production output, and export-market coverage support classification as a specialized technology manufacturer rather than only a trading or service intermediary.

CertificationsThe supplier reports holding ISO 9000 and ISO 9001 certification for its management systems. These are explicit certifications relevant to quality-management processes, although no certificate numbers, validity dates, or scope details are provided.

R&D capabilityThe supplier reports new products during the past year, 6–10 years of total R&D engineer experience, 3D software design capability, and ODM services. Its specialized laser product portfolio further supports technical development capability, although no SDK is available.

Production capacityThe supplier reports 100% finished-product inspection, raw-material traceability, 6–10 quality-control staff, and lead times within 15 workdays in both peak and off-peak seasons. However, it explicitly has no in-stock service capability, and the manufacturing-capacity contract status is unknown; therefore, production capability is supported but not fully verifiable.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product and design adaptation capability.

Product Q&A

Q:Q1: How does this module integrate with the ESP32?

This module is highly compatible with the ESP32. It communicates via standard interfaces like UART or SPI using 3.3V CMOS logic levels, which perfectly matches the GPIO voltage of the ESP32 without needing additional level shifters. Furthermore, because the module handles the heavy ToF data processing internally, it significantly reduces the computational burden on the ESP32, allowing your ESP32 to focus on Wi-Fi/Bluetooth connectivity and high-level application logic.

Q:Does the ESP32 need to run complex algorithms for depth calculation?

No. One of the biggest advantages of this module is its built-in computing power. The internal processor (DM3602) executes all the necessary ISP (Image Signal Processing) and application algorithms (like range finding, gesture recognition, and human sensing). The ESP32 only needs to receive the final, ready-to-use results via serial communication.

Q:What are the power supply requirements when pairing this with an ESP32?

The ToF module requires a stable 5V power supply capable of delivering at least 500mA. Since the ESP32 typically operates on 3.3V or 5V, you can easily power both from a single 5V USB source, ensuring sufficient current for the VCSEL laser emitter during active ranging.

Q:Can this setup be used for privacy-preserving presence detection?

Absolutely. Unlike traditional RGB cameras, this 3D ToF sensor only captures low-resolution depth data (distance matrices) rather than visual images. When paired with the ESP32, it creates an ideal, privacy-safe solution for smart home applications such as elderly fall detection, room occupancy monitoring, and automated lighting control.

Q:What communication protocols are supported between the module and the host MCU?

The module supports UART, SPI, and I2C interfaces. For most ESP32 projects, UART is recommended for ease of use, while SPI is ideal if you require higher data throughput or faster response times for dynamic applications like gesture tracking.
