About
CircuitMaker is not just a free EDA software tool from Altium, it’s also a community of creative people and design content, working together to invent circuits and electronics products for a better future. For turning great ideas into real products, you need design tools that won’t limit your imagination or hold you back. CircuitMaker has all the power you need to design high quality schematics and Printed Circuit Boards, with no artificial limits on layer counts or board area. Best of all it’s free. The CircuitMaker community is where you will find great reference designs, and be able to promote and rate other projects in the community. You can even set up teams for collaborative design efforts. We think you deserve better design tools, made specifically for you, to turn great ideas into reality. That’s why we’ve created CircuitMaker. Besides being a collaborative community for electronic design content, CircuitMaker is Schematic & PCB design software.

About
Sensbench is a browser-based circuit and microcontroller simulator for learning, prototyping, and testing Arduino, ESP32, Raspberry Pi Pico, and other supported boards. Users place virtual boards and components on a breadboard, connect circuits, edit sketches, compile firmware, and run it in an emulated microcontroller while viewing serial output and component behavior. It also supports SPICE analog simulation and mixed digital-analog circuits. Guided examples and virtual sensors, displays, LEDs, relays, and other parts are included. An optional AI builder turns a written project request into a parts list, wiring plan, and firmware, while an MCP server lets compatible AI clients operate the workbench. The core simulator is free to use in a web browser; optional AI credits and subscription plans add AI usage and project features. Sensbench also sells physical project kits with pre-flashed boards and guides, including kits designed to connect to Home Assistant over local Wi-Fi.
