Ohmbo – AI PCB Design Tool for Automated Circuit Board Design and Prototype Manufacturing

Ohmbo is an AI-powered PCB design and prototype manufacturing platform developed by Rolitt Inc. It helps hardware startups, electronics engineers, makers, students, and product developers transform circuit board ideas into physical prototypes using natural language.

Instead of starting with complex electronic design automation (EDA) software, users can describe their circuit requirements in plain English. Ohmbo generates a draft schematic, selects electronic components, creates a PCB layout, provides a 3D board preview, and prepares a bill of materials (BOM).

The platform combines AI-assisted PCB design, engineering review, and prototype manufacturing into one workflow, helping users move from initial ideas to assembled circuit boards.

What Is Ohmbo AI PCB Design?

Ohmbo is an AI-assisted circuit board design tool that simplifies the early stages of electronic hardware development.

Traditional PCB design software often requires knowledge of schematic capture, component footprints, circuit connectivity, and board layout. Ohmbo offers a more accessible starting point by allowing users to describe their requirements conversationally.

For example, users can request a custom ESP32-based controller board with sensors, connectors, and specific dimensions.

The AI creates an initial design that users can inspect and refine before placing a manufacturing order.

Ohmbo focuses primarily on early-stage hardware prototyping and two-layer PCB designs within its Proto Kit scope.

Key Features of Ohmbo AI PCB Design Software

1. AI-Powered PCB Design From Text

Ohmbo allows users to generate initial circuit board designs using natural-language instructions.

Users can describe their desired board functionality, preferred components, physical dimensions, and connector requirements.

The platform translates these requirements into structured electronic design outputs, reducing the need to create every initial design element manually.

2. Automated Schematic Generation

Ohmbo generates draft electronic schematics based on user requirements.

The schematic generation workflow includes component selection, circuit connections, and relevant design structures.

This feature can help hardware developers prepare an initial circuit design before engineering verification.

3. AI-Assisted PCB Layout Generation

Ohmbo converts circuit requirements into an initial PCB layout.

Its design workflow supports two-layer circuit boards within the standard Proto Kit specifications.

Users can review the generated layout and request modifications through natural-language instructions.

4. Interactive 3D PCB Preview

Ohmbo provides a three-dimensional preview of generated circuit board designs.

This allows users to inspect the proposed board visually before proceeding with manufacturing.

The preview is particularly useful for reviewing component placement and the board's overall physical arrangement.

5. Automated Bill of Materials (BOM)

The platform generates a bill of materials containing components associated with the proposed circuit design.

This helps users understand the electronic parts required for their hardware prototype.

The BOM forms part of the design information available during the review process.

6. Natural-Language Design Modifications

Users can refine their initial PCB designs by describing the changes they want.

Instead of restarting the design process, they can request adjustments to components, connections, or layout requirements.

This conversational workflow makes early-stage design iteration more accessible.

7. Professional Engineering Review

Ohmbo combines AI-generated designs with human engineering oversight.

After an eligible manufacturing order is placed, a factory engineer reviews the design for manufacturability and electrical issues.

The engineer provides a written review report before fabrication proceeds.

This review stage is important because AI-generated PCB designs should not be assumed to be electrically correct or manufacturing-ready without verification.

8. PCB Prototype Manufacturing and Testing

Ohmbo connects the design process with physical prototype manufacturing.

Its Proto Kit includes five assembled and tested two-layer circuit boards manufactured through its Shenzhen production arrangement.

Each board is accompanied by a written test report.

This integrated workflow helps users progress from digital circuit concepts to physical hardware prototypes.

How Does Ohmbo Work?

Ohmbo follows a workflow that combines AI-assisted design, user review, professional engineering verification, and manufacturing.

Step 1: Describe Your Circuit Board Idea

Start by describing the electronic device or circuit board you want to create.

Include relevant requirements such as board functionality, preferred microcontrollers, sensors, connectors, and size restrictions.

Step 2: Generate an AI PCB Design

Ohmbo processes the description and generates an initial design.

The output includes a draft schematic, component selection, PCB layout, 3D preview, and BOM.

Step 3: Review and Refine the Design

Inspect the generated design directly in the browser.

Request changes using plain English until the proposed design better matches your requirements.

Step 4: Order the PCB Prototype Kit

Once satisfied with the design preview, users can purchase the Proto Kit for engineering review and manufacturing.

Step 5: Complete Engineering Verification

A factory engineer evaluates the proposed design for manufacturing feasibility and electrical issues.

The engineer provides a written report as part of the review process.

Step 6: Manufacture and Test the PCBs

Following engineering approval, the boards proceed to manufacturing.

The Proto Kit includes five assembled and tested two-layer PCBs, along with written test reports.

Ohmbo Use Cases

Ohmbo vs Traditional PCB Design Software

Traditional EDA tools such as KiCad, Altium Designer, EasyEDA, Autodesk Eagle, LibrePCB, and Fritzing support electronic design workflows with varying levels of professional control and functionality.

Ohmbo takes a different approach by emphasizing natural-language generation and integrated prototype manufacturing.

Rather than replacing every professional EDA workflow, Ohmbo is designed to simplify the creation of an initial custom circuit board.

Complex high-speed electronics, advanced multi-layer designs, and sophisticated multi-board systems may still require specialized engineering expertise and traditional EDA tools.
