Analog Devices Inc. EVAL-CN0569-PMDZ

Overview

EVAL-CN0569-PMDZ from Analog Devices is a Pmod-form-factor infrared gesture recognition evaluation board built around the ADPD2140 angle sensor and ADPD1080 photometric front end. It delivers up to 512 samples/second at ≤20 cm sensing range, supports I²C host interface, and enables touchless hand-gesture detection (swipe, click) for embedded human-machine interfaces.

For engineers reviewing the EVAL-CN0569-PMDZ datasheet, EVAL-CN0569-PMDZ pinout, EVAL-CN0569-PMDZ application, or EVAL-CN0569-PMDZ equivalent, this board provides verified optical gesture sensing reference design with full schematics, BOM, layout files, and Python/MATLAB algorithm support - ideal for rapid prototyping of healthcare, access control, and consumer touchless UIs.

Technical Context

The EVAL-CN0569-PMDZ implements a synchronized pulsed IR sensing architecture: dual ADPD2140 sensors capture 2-axis incident light angles within ±35° FOV, while the ADPD1080 drives 850 nm LEDs, digitizes photocurrents via configurable transimpedance amplifiers and 16-bit ADC, and outputs time-sliced digital data over I²C.

Power and signal integrity are maintained by an LT1761 1.8 V LDO regulator and bidirectional level translation using LTC4313-3 (I²C lines) and ADG3301 (GPIO0), enabling seamless interoperability with 3.3 V Pmod-compatible hosts like EVAL-ADICUP3029.

FAQ

What is the primary function of the EVAL-CN0569-PMDZ?

The EVAL-CN0569-PMDZ is a fully assembled and tested infrared gesture recognition evaluation board. It integrates dual ADPD2140 angle sensors and an ADPD1080 photometric front end to detect hand movements (swipe, click) within 20 cm. The EVAL-CN0569-PMDZ provides calibrated I²C output and supports algorithm development in Python or MATLAB - making it a turnkey solution for touchless UI validation.

Which host platforms is the EVAL-CN0569-PMDZ compatible with?

The EVAL-CN0569-PMDZ uses the standard 6-pin Pmod I²C interface (2×3 header, 100 mil pitch) and operates at 3.3 V logic. It is explicitly validated with the EVAL-ADICUP3029 development board but works with any Pmod-compatible host supporting I²C clock stretching and 1.8 V–3.3 V level translation - including Arduino, Raspberry Pi Pico (with adapter), and Digilent FPGA boards.

Does the EVAL-CN0569-PMDZ include firmware or software?

Yes - the EVAL-CN0569-PMDZ ships with prebuilt firmware for the ADICUP3029 microcontroller and a Python-based "Theremin" script for gesture visualization and real-time terminal output. Full source code, register configuration sequences, and gesture classification algorithms (including intensity thresholding and angular slope analysis) are provided in the CN0569 User Guide and design files.

Can the EVAL-CN0569-PMDZ be used for distance sensing as well as gesture recognition?

Yes - the dual ADPD2140 configuration on the EVAL-CN0569-PMDZ enables both 2D angular tracking and relative distance estimation. By comparing intensity ratios and triangulating signals across two spatially separated sensors, the board supports basic proximity and depth-aware gesture differentiation - confirmed in CN-0569 Rev. 0 test data (Figures 4–6).

What external components or tools are required to operate the EVAL-CN0569-PMDZ?

To operate the EVAL-CN0569-PMDZ, you need: (1) a Pmod-compatible host (e.g., EVAL-ADICUP3029), (2) a micro USB cable, (3) a host PC running Python 3.6+, and (4) the CN0569 Theremin script. No additional optics, lenses, or calibration hardware is required - the board includes integrated 850 nm LEDs, 3D-printed baffles, and factory-aligned ADPD2140 sensors.
