PS4 Portable PowerBoard (ESP32 Edition)

My name is Antonio Trezza, and I am developing one of the most advanced portable console engineering projects: a fully handheld system based on the PlayStation 4 Slim motherboard.

The heart of the system is a fully custom PCB that replaces the original PS4 power supply and integrates all essential electronics required for portable operation,

Including:

• 3S Lithium Battery Management System (BMS) integrated on-board
• USB-C Power Delivery fast charging with power-path management
• Multiple high-efficiency buck converters for all PS4 power rails
• PWM-controlled cooling fan for APU
• Comprehensive protection circuitry (OVP, UVP, OCP, thermal protection)
• Integrated ESP32-S3 System Controller
• Integrated audio amplifier supporting: two speakers, headphone output

An on-board ESP32-S3 module acts as the system’s intelligent controller, responsible for:

• PWM fan speed control with dynamic profiles
• Digital audio volume control (buttons → ESP32 → electronic volume adjustment)
• Battery percentage calculation and monitoring
• APU temperature monitoring for safe thermal management

This creates an intelligent, efficient and safe power and control system tailored for a portable PS4 Slim.

This project is a complete electrical redesign of the PS4 Slim for portable use — not just a cosmetic modification.

Similar PS4 handheld builds on YouTube have gained hundreds of thousands of views, demonstrating strong public interest in high-level engineering projects.

My build will feature:

• Showcase the PCB, explain the PCB
• Custom Controls (Dualshock 4 to Handheld Controls)
• Fan integration, mounting
• power system testing
• enclosure design
• a full handheld gameplay demonstration

The entire process will be documented as a multi-episode YouTube series, marking the launch of my new engineering-focused channel.

Why PCBWay?

This project requires a fabrication partner capable of handling:

• mixed-signal routing
• high-current power design
• integrated BMS
• USB-C PD circuitry
• ESP32-S3 module placement
• audio amplifier sections
• fast-switching buck converters

PCBWay’s high manufacturing quality and reliable PCBA services make it the ideal partner.

In return for sponsorship, PCBWay will receive:

• clear credit in every video
• links in descriptions
• detailed presentation of PCBWay’s manufacturing quality
• visibility throughout the entire project series
• long-term partnership potential for future builds

Project Status

The PCB design is fully completed:

• Schematic
• PCB Layout
• Gerber files
• BOM
• CPL

All files are ready and included for review. (Dropbox Link)

I send you also a few Pictures of the Project like Renders etc.

Last Words:

I hope PCBWay will sponsor this Project and i hope we can become long time Partners :)

PS: If i made mistakes with my English i am really sorry actually i am from Switzerland we LOVE technology :)
