1.Easy to use and quick to get started

2.The process supports design scales of 300 devices or 1000 pads

3.Supports simple circuit simulation

4.For students, teachers, creators


1.Brand new interactions and interfaces

2.Smooth support for design sizes of over 30,000 devices or 100,000 pads

3.More rigorous design constraints, more standardized processes

4.For enterprises, more professional users

WARNING: The schematics on the project home page seem to update somewhat randomly. Make sure to open the actual project to see the latest schematics.

NB While this is intended to be a new generation of ELRS receiver it is not compatible with existing receivers, nor is it supported by the main project. Code for it is in my fork of the elrs handset project.
