How JLCPCB Helped a Non-Verbal Girl Communicate Her Needs

How can a non-verbal child express her needs to caregivers? It’s a question parents hope to never face. An American developer group focused on open-source assistive technology, created a customizable communication device for a 3-year-old girl with special needs. With support from JLCPCB, the team built a low-cost, upgradable tool that allows her to communicate using simple button presses.

Needs Communication System

Project Overview:

The project began in Thailand when the founder of developer group met this special needs child. After returning to United States, he led the developers to update his original work and continue the commitment to building open-source tools for people with unmet needs. With help from the folks at JLCPCB, the team produced a personalized device that lets the child press buttons to trigger recorded speech—expressing needs like hunger or discomfort.

Key Components Used:

Multilayer PCB, rp2350 processor, EsD protection, I2S Audio with Amplifier, Display, Rotary Encoder, Microswitches.

Key features:

1.Multi-sensory feedback: Buttons vibrate, lights flash in different colors, and the device speaks in the users native language.

2.Touchscreen interface: A color LCD screen adds visual cues.

3.Modular design: The electronics are separated by function, combined with 3D-printable plastics, and use of Python the project was brought to life in a way that is easily modified for changing needs and other special needs individuals.

Inside the device is a custom PCBA (Printed Circuit Board Assembly), manufactured and verified by JLCPCB.

How JLCPCB Made It Possible:

The device is simple in design, easy to modify remotely. It can be produced using any 3D printer and basic soldering skills worldwide. The key to achieving this project was to maximize functionality at a low cost, ensuring that the device had the necessary performance in a small form factor while enabling rapid prototyping.

1.Fast Delivery & Affordable Manufacturing

After uploading design files to JLCPCB’s online platform, the developer placed an order at a low cost. Within just 7 days, the finished PCBA—with components placed—was delivered through logistics. This rapid turnaround helped the team stay on schedule and within budget.

2.Free Design Verification

JLCPCB’s online Gerber file verification helps catch layout issues early. Their system corrected mismatches in packaging directions between different libraries, preventing errors during manufacturing. The result: a working, compact, child-friendly circuit board layout.

3.Reliable Software Support

The team used EasyEDA, JLCPCB’s free PCB design software, which integrates layout tools and a rich component library. The developer shared:“The software is extremely practical and free. The integrated component library is fantastic. We’re now developing an emergency communication device for people with selective mutism and limited motor control—and plan to continue using EasyEDA in the future.”

From Prototype to Showcase:

The next iteration of the PCBA was delivered within a week, allowing the team to demonstrate two different human interfaces systems at Open Sauce 2025, a major event for makers and innovators.

Conclusion:

JLCPCB was essential in turning this assistive device from an idea into reality. Their fast delivery, affordable manufacturing, and free design checks allowed the developer team to improve the design quickly and solve real-world problems. Thanks to the combined teams, a non-verbal 3-year-old girl now has the tools to express her needs—and the project is already inspiring new tools for others with special needs.
