I verified/set the Datasheet URL to the PixArt PAT9125EL-TKIT/TKMT datasheet, and the main mismatches are: VSS is typed as Power Out but should be Ground, Manufacturer Name and Part Type are missing, and all terminals lack Section, Pin Group, and Pin Orientation metadata. Full audit is in PAT9125EL-TKIT Part Datasheet Audit.

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, VDD, gnd_1 gnd_2 etc NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

Looking for "pin description power ground I2C interface pins LED motion ID_SEL" in PAT9125EL-TKITPAT9125EL-TKMT.pdf?ext=.pdf

Done — I grouped each existing pin into exactly one functional group: Power (VLD, VDDA, VDD), Ground (VSS), I2C Communication (SCL, SDA), and Control (MOTION, ID_SEL). I also corrected VSS to Ground; note the datasheet lists a backside TEST NC pin, but it is not currently present in the symbol.

PAT9125EL-TKIT

PAT9125EL-TKIT thumbnail
The PAT9125EL-TKIT from PixArt Imaging Inc. is a low-power optical tracking miniature chip designed for precise motion detection using laser-based optical navigation technology. It integrates both the optical sensor and VCSEL laser light source into a single compact package, enabling accurate tracking even on smooth or glossy surfaces.
This device captures sequential surface images and processes them internally to determine movement direction, speed, and displacement (X/Y data), which can be accessed by a host controller via digital interfaces.
It is particularly suited for space-constrained, battery-powered, and enclosed systems, eliminating the need for mechanical components like code wheels or special surface markings.
Key Features Integrated optical sensor + VCSEL laser (850 nm) in a single package No external lens required, simplifying design Wide depth of field (DOF): 1–30 mm, even on reflective surfaces Programmable resolution up to ~1275 CPI Supports I²C (TKIT) interface (SPI variant available as TKMT) Motion detection interrupt output Built-in oscillator (no external clock needed) Low power consumption: Run: ~0.7 mA Sleep: down to 10 µA Power-down: ~5 µA Pre-calibrated laser (no calibration required) IEC/EN 60825-1 Class 1 eye-safe laser compliant Key Specifications Supply Voltage: VDD: 1.7–3.6 V VLD (laser): 2.7–3.6 V Max Tracking Speed: up to ~30 inches/sec Package: 8-pin LGA (3.5 × 3.2 × 1.0 mm) Interface: I²C (for TKIT variant)
