Creating Your First Board

The Eagle user interface consists of:

  • The schematic editor for creating circuit diagrams
  • The board layout editor for defining physical PCBs
  • The libraries for managing components

Let’s walk through an example flow to create your first custom PCB board design with Eagle Free:

  1. Schematic Capture – Use parts from the existing libraries to wire up a circuit in the schematic editor. Common components like resistors, LEDs, microcontrollers, etc. are available.

  2. Board Layout – Transition the schematic into the board editor to define traces, pads, dimensions, etc. A 2-layer red/blue board will meet most hobbyist needs.

  3. Design Rule Check – Validate clearances, sizes, etc based on manufacturability requirements. Eagle helps avoid common rookie layout issues.

  4. CAM Processing – Generate Gerber and drill files with the CAM processor ready for sending to your preferred PCB fabrication vendor.

  5. Manufacturing – Upload the CAM outputs to your manufacturer of choice and order your finished boards!

While the core PCB design flow is straightforward, Eagle does include learning curves around the multitude of features and customization possible. Taking advantage of online tutorials and help resources will aid getting up to speed faster across the toolset.

Capabilities of Free vs. Premium

While the free version delivers tremendous value, Eagle Premium does provide a few advanced capabilities that may benefit some users:

More Space

The free edition only allows a maximum PCB size of 100mm x 80mm with two routing layers. This compact canvas suits hobbyist projects using common prototyping boards like single-sided FR-1.

However, more complex designs demand larger boards sizes and layer counts – achievable through an upgrade. Premium supports boards up to 160x100mm with four copper layers, while 10×16 inches (or larger) is possible with Professional.

Added Features

Certain features are also restricted within the base Eagle package, including:

  • Auto-routing algorithms to simplify trace wiring
  • Accelerated version control integrations
  • Extended file format support options beyond standard exports

Again, Premium lifts some of these constraints to improve design efficiency. Most notably, access to the auto-router – a handy tool for quick trace routing that eliminates tedious manual work.

For advanced capabilities though, Eagle Professional really opens up more custom interfaces, extensive scripting APIs, high-speed validation, and other specialized functionality targeting demanding engineering contexts.

Better Support

By nature of the small-scale focus, Autodesk provides community discussion forums and online help content for navigating Eagle Free. This DIY ethos empowers hobbyists to independently troubleshoot issues.

However, growing companies may desire more formal support channels, whether for expedited answers or tailored onboarding. Autodesk’s premium paid plans include various standard, extended, and priority customer service response options to suit larger organizations.

Example Projects with Eagle Free

While Eagle Free is intentionally limited in scope, it still can facilitate an enormous range of hobbyist projects spanning wearables, drones, robots, internet-of-things devices, and electronic experiments.

Here are some examples of fun beginner applications possible with the free Eagle software:

Custom Badges

For conferences events and clubs, PCB badges with integrated lights, buttons, and sensors can create unique interactive credentials. Solder components onto artistically shaped boards made possible in Eagle.

IoT Prototypes

Connecting simple microcontrollers like Arduinos over WiFi to the cloud only takes a small pcb footprint designable for free. Enable rapid experiments with networked objects sending data.

Wearables

Rings, bracelets, pendants, earrings or watches with LEDs can all leverage custom Eagle PCBs shaped into stylish accessories. Embed sensors to light up based on touch, orientation or other input.

These examples demonstrate the breadth of hands-on applications possible with Eagle Free before any paid upgrades become necessary. Let your imagination guide what types of gadgets, tools or experiments you prototype along the way to learning PCB design.

Eagle Free Alternatives

While Eagle Free delivers adequate hobbyist functionality, some limitations still exist. Common restrictions users may outgrow over time include:

  • Small maximum PCB area
  • Only two routing layers
  • No auto-router access
  • Limited component libraries

In response, developer communities have created free and open source PCB tool alternatives without such arbitrary constraints. Popular options include:
