Cables and Connector Systems

Guide to cable types, connector compatibility, cable routing, and common wiring mistakes when assembling 3D-PAWS systems.

Overview

3D-PAWS stations use standardized cables and connectors to link sensors, data loggers, and power systems. Understanding these connections is essential for successful assembly, troubleshooting, and maintenance.

Detailed wiring diagrams are provided in the data logger-specific sections of this manual.


Common Connector Types

Type
Use Case
Key Features

Grove

I2C / Analog sensors

4-pin plug-and-play

Dupont

Flexible wiring

Male/female pin headers


Connector Terminology

Male vs Female

  • Male: Exposed pins

  • Female: Socket holes

Must match correctly to avoid damage or loose connections.


Signal Types

  • Analog: Continuous voltage signal (requires correct pin mapping)

  • Digital (I2C): Bus communication allowing multiple sensors (requires correct wiring and addressing)

Most 3D-PAWS sensors use Grove (I2C or analog) connections, which simplify wiring and reduce errors.


Cable Management

Proper cable routing improves reliability:

  • secure cables to prevent movement or strain

  • avoid sharp bends or tension

  • keep cables away from moving parts

  • protect connections from moisture

  • use zip ties or printed cable clips


Common Mistakes

❌ Problem
✅ Fix

Wrong pins

Double-check pinouts

Reversed power/ground

Verify red/black wires

Loose connections

Ensure secure crimps

Incompatible connectors

Match male/female connectors

Poor cable routing

Use clips or zip ties


Best Practices

  • verify connections before powering on

  • label cables when possible

  • use consistent wiring practices

  • double-check sensor pinouts

  • test I2C addresses before final assembly
