Electronics

Overview

The electronic system is composed of modular PCBs responsible for power distribution, sensing, and data acquisition. All boards were designed using open-source tools and are available for modification and reproduction.

Important:
All components must be assembled according to the provided PCB layout files (.brd and .kicad_pcb). Component placement, orientation, and routing should strictly follow the design files.

Power Supply Board

This board is responsible for distributing power to the system and interfacing with the external power supply.

Main components:

• 3300 µF capacitor
• 22 nF capacitor
• KCD6 switch
• 2 × KRE 2V connectors
• Banana connectors (male and female, red and black)
• XT60 connectors (male and female)

These boards are used for angular velocity measurement.

Main components:

• 4 × DRV5011 Hall sensors
• 4 × 22 nF capacitors
• 4 × KRE 2V connectors

Potentiometer Board

This board provides angular position measurement and signal conditioning.

Main components:

• Precision potentiometer
• Standard potentiometer
• L7808 voltage regulator + heat sink
• 2 × LM358 operational amplifiers
• 2 × 1 µF capacitors
• 4 × 100 nF capacitors
• 2 × 33 kΩ resistors
• 2 × 10 kΩ resistors

Wiring and Integration Guidelines

• Female connectors should be soldered directly onto the PCBs, while male connectors are used on cables
• Banana connectors are used for motor power connections
• The XT60 connector interfaces the external power supply with the system
• Power lines should use silicone-insulated wires
• Sensor connections should use shielded cables to reduce noise
• PCBs can be mounted on the aluminum structure using hammer nuts and screws
• The potentiometer board must be mechanically coupled to the shaft for accurate angle measurement
• Wiring layout may be adapted depending on system configuration and physical constraints
