I will do esp32 s3 handheld electronics, custom pcb, firmware, lcd gui and 3d enclosure

From Pocket-Sized Idea to Working Hardware

Building a handheld electronic product takes more than putting an ESP32-S3 on a board. The PCB, firmware, display, controls, power system and enclosure all need to work together as one reliable product.

I can help turn your concept into a functional ESP32-S3 handheld prototype, including custom electronics, embedded firmware, LCD GUI and a practical 3D enclosure.

What you will get:

• ESP32-S3 schematic and PCB files
• Embedded C/C++ firmware
• LCD/display and GUI integration
• Buttons, sensors and peripheral integration
• Power and battery circuitry
• Manufacturing-ready Gerbers & BOM
• 3D enclosure files in STEP/STL
• Hardware/firmware integration support

What sets me apart: I focus on the complete product, not just the circuit board. Mechanical fit, electronics, firmware and user interaction are considered together from the start.

Have a handheld product in mind? Send me your requirements and lets turn it into a working prototype.
