As an experienced and qualified electrical engineer and PCB designer, I am eager to take on your Raspberry Pi USB-C Splitter HAT project. With over 8 years of experience in circuit design and PCB layout, I assure you that I possess the skills necessary to create a HAT that meets your specifications. Using my expertise with Eagle, Altium, KiCAD, and EasyEDA, I will provide you with a schematic capture, complete PCB layout (Gerber + drill + pick-and-place), and an annotated BOM - all respecting the Pi HAT spec as desired. Moreover, my proficiency extends to MATLAB/SIMULINK and Python programming which means I am more than capable of taking responsibility for the PD negotiation logic and any necessary embedded code or configuration needed for the PD controllers. My career has also encompassed extensive work with embedded systems (we're talking AutoCAD, Multisim, Proteus, LTspice, PSpice if you count 'em) which ensures I can adeptly handle monitoring and control tasks your Raspberry Pi requires. Lastly, my dedication to quality extends beyond circuitry - I have a knack for writing technical content such as bring-up plans and blueprints for assembling boards aligned with measurements you can replicate. In addition to this project, in the future I can facilitate custom cable-making as well as metal chassis construction. By hiring me not only do you get a deeply skilled professional but also someone dedicated to seeing your ideas realized responsibly and effectively.

Hi there, I read your brief and I can design a Raspberry Pi HAT that takes a single USB-C PD input and fans out to 3–4 downstream USB-C ports carrying power + data, with each output able to negotiate its own PD profile while maintaining a reliable USB link (USB 3 where feasible, otherwise solid USB 2). I’ll also route Pi power through the HAT’s power pins and design for thermal/100W operation. You’ll receive full schematics, a Pi HAT-compliant PCB layout (Gerbers/drill/PnP), an annotated BOM with orderable part numbers/lead times, and any required PD controller firmware/config. I can add an optional PoE front-end feeding the same rail, plus monitoring (and where supported, control) of PD budgets from the Pi via I²C/USB so you can track power headroom in real time. Message me and I’ll share a concise architecture (PD controllers + USB hub/retimers as needed), a milestone plan, and key SI considerations to avoid high-speed pitfalls. Best regards, Samuel Tshibangu

@engrusmanfaiz

Hello, I can design a production-ready Raspberry Pi HAT with a single USB-C PD input and multiple downstream USB-C ports carrying both power and data. My approach uses a high-efficiency 100W PD sink, per-port PD controllers for independent negotiation, and a robust USB hub architecture. The Pi will be powered via the HAT and able to monitor PD contracts, current, and power budget over I²C. I will deliver full schematics, Pi-HAT-compliant PCB layout, Gerbers, and a sourcing-ready BOM. PD configuration firmware and a clear bring-up/test plan will be included. I am confident in managing thermal, signal-integrity, and hot-plug risks at this power level.

@AwaisChaudhry

Hi, I’m Muhammad Awais. I understand you want a Raspberry Pi HAT that accepts a single USB-C PD input and splits it into three or four downstream USB-C ports with independent PD negotiation, while keeping a reliable USB data link to the Pi. I’ll design a compact, thermally robust board inside the standard HAT footprint, with a PD controller per port, proper protection, level shifting, and a common rail that can handle up to 100W input. The layout will preserve Pi HAT clearance, maintain signal integrity for USB2/USB3 speeds where feasible, and include a front-end PoE option if practical. I’ll deliver schematic capture (all controllers and protection), complete PCB layout (Gerber, drill, pick-and-place), annotated BOM with lead times, embedded code/config for the PD controllers, and a concise bring-up/test plan you can replicate. I will also address PD negotiation logic strategies and potential signal-integrity traps to watch for. What is the preferred PD controller family (e.g., TI, ST, or open-source firmware), and do you require explicit PD sink/source monitoring data exposed over a GPIO or I2C interface? I’ll tailor the solution to monitor or control PD sinks/sources where possible and keep reports within your budget. If desired, I can also discuss custom cables and chassis later. Best regards,

@PCBDESIGNER38

Hi, I can design a Raspberry Pi HAT that accepts a single 100W USB-C PD input (with optional PoE++ front end) and distributes it to 3–4 downstream USB-C ports with independent PD negotiation and USB 3.0 (or USB 2.0 where required) data paths. The design will include proper PD controllers, power-path management, protection, thermal planning, and Pi-side monitoring over I²C for real-time power budgeting. You’ll receive full schematics, production-ready PCB layout (Gerber, drill, PnP), annotated BOM with sourcing data, PD firmware/configuration files, and a structured bring-up/test plan. I have experience in high-power DC design, USB signal integrity, and EMI-aware layout, and I can also support future cable and enclosure development. Regards, Ruman

Designing a Raspberry Pi HAT that takes a high power USB C PD input and redistributes it to multiple USB C ports with independent PD negotiation and stable data links is not a problem with the right PD architecture and high speed layout discipline. Well, what I can do for you as an electronics engineer with 8+ years of experience is design a Pi compliant HAT that accepts up to 100 W USB C input, implements proper PD sink and source controllers, robust protection and power path design, and routes USB data with controlled impedance so each downstream port can deliver power and maintain reliable communication. In fact, I have designed complex embedded and power electronics including a custom security camera circuit design for a USA based requirement, a real time low power 8 bit SAR logic circuit at circuit level, and a high power dimmer around 10000 watts, so working with high current paths, protection, and manufacturable PCB layouts is familiar territory for me.

@jaredj49

Hi, I’m an experienced high-power and high-speed PCB design engineer, and I can develop a fully compliant HAT for Raspberry Pi that accepts a 100W USB-C PD input and distributes independently negotiated power + data to 3–4 downstream USB-C ports within the standard mechanical and thermal envelope. My architecture will use a dedicated upstream PD sink controller, per-port PD source controllers with autonomous policy engines, a USB 3.0 hub (with controlled-impedance routing and fallback to USB 2.0 where SI margins demand), and a 20V main bus feeding high-efficiency synchronous buck stages for flexible 5–20V output negotiation. Optional PoE++ (802.3bt) can be integrated as an alternate input rail with ideal-diode OR-ing into the same DC bus, while precision current sensing and thermal monitoring will allow the Pi to supervise PD contracts and total power budget over I²C. Deliverables include complete schematic capture (controllers, protection, level shifting), impedance-controlled PCB layout (Gerber, drill, pick-and-place), annotated BOM with sourcing and lead-time estimates, PD configuration firmware ready to compile, and a structured bring-up/test plan covering PD negotiation, load validation, and USB signal integrity checks. Best regards. Jared

@wanto220418

Hi Your Project is very interesting and highly challenging! I have developed a 5-channel distributed USB Power Delivery (PD) source controller with 5 power bank inputs and 5 PD outputs. Each port dynamically advertises its available power budget based on the number of connected power banks. The design uses the STUSB4xx series from STMicroelectronics. Dynamic means the system can renegotiate and update its PDOs (Power Data Objects) in real time. When a power bank is connected or disconnected, the controller recalculates the total available power and immediately adjusts the advertised budget, ensuring stable and efficient allocation. I have also developed a PD sink controller for battery charging using TPS2xxx series ICs from Texas Instruments, and a 5-channel PD sink system for IoT devices. Additionally, I have worked on PoE solutions for the Raspberry Pi Compute Module and PoDL implementations for SPE modem systems. I think for your case, real-time power measurement of the Raspberry Pi will be required so the remaining budget can be dynamically advertised to 3 PD source ports, as its consumption varies with workload I would be glad to contribute my experience to ensure a successful outcome. Thanks - Hendra

Best USB-C Power Raspberry Pi HAT Design Expert ⭐⭐⭐⭐⭐ Hi, Thank you for posting your project, “Raspberry Pi USB-C Splitter HAT.” I’ve reviewed your requirements and can help you design a production-ready Raspberry Pi HAT that accepts a single USB-C PD (up to 100 W) input and intelligently distributes both power and data across three to four downstream USB-C ports, each with independent Power Delivery negotiation and stable high-speed connectivity. I bring 11+ years of experience in USB-C Power Delivery (PD 2.0/3.0/3.1), high-power DC design, Raspberry Pi HAT compliance, and high-speed USB signal integrity (USB 2.0/USB 3.x). ✅ How I’ll Help You Succeed 1. Select and integrate PD controllers, protection, and power switches suitable for 100 W operation within the Pi HAT form factor. 2. Design a signal-integrity-safe PCB layout (controlled impedance, length matching, thermal relief) compliant with the Raspberry Pi HAT spec. 3. Enable Pi-side monitoring/control of PD status (current, voltage, contract state) via I²C/SPI where supported. ✅ Before I Start, One Quick Question: Would you like me to first define the PD negotiation and power-budget architecture (including PoE/PoE++ feasibility) or proceed directly with the full schematic and PCB layout based on your current vision? If you share that, feel free to message me, and we can align quickly. Best regards, Prat PCB Must Innovations

@FranciscoSilvi

Hi There! -First of all, I believe I can complete your project for less than 750 USD; I typically charge around 300-400 USD for a PCB like this. -As you can see by visiting the portfolio on my profile, I have extensive experience designing PCBs for mass-produced products, not just KiCAD renders. I work with Altium, EAGLE, and KiCAD, as well as others like Allegro. I can diagnose noise issues in your PCB and solve them before production. -I have extensive experience with power electronics; you can see an automotive PDM with eight 25A outputs and ten 8A outputs, totaling a maximum of 400A. I have experience with Power Delivery devices, USB 3.2 Gen 2, and USB 4.0. I use the GCT USB4910-00-A connector, which is priced at 0.88 USD on Mouser and provides all 24 pins. -This is not an AI-generated bid like most of those you will see, which I know can be very frustrating. For this reason, I do not spend much time on them in detail; to get a more detailed consultation, we can discuss it via chat. Regards!

@yaroslavmark

✅Okay, I got what you want exactly. I am a senior hardware design engineer specializing in high-power USB-C and embedded systems, with over 10 years of experience delivering mixed-signal PCB designs, PD power architectures, and Raspberry Pi–based carrier boards. In my opinion, the cleanest way to approach this is to treat the 100W USB-C PD input as a managed power backbone, using a dedicated PD controller with external FETs and current monitoring, then distribute power through independent PD source controllers per downstream port. I would isolate high-speed data routing carefully with controlled-impedance USB 3.0 pairs and keep PD policy logic handled either via I²C-accessible controllers or a small STM32-class MCU so the Pi can monitor contract states and total power budget in real time. This project is very similar to my previous works. Recently, I designed a 4-port USB-C industrial hub with 65W shared input and independent PD contracts using TPS65987D controllers, including a 6-layer impedance-controlled PCB that passed USB 3.0 eye diagram validation at 5Gbps. I also built a PoE++ (802.3bt, 90W) powered embedded carrier board integrating a Silvertel module and digital current telemetry, with full thermal modeling for 80W sustained loads inside an aluminum enclosure. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and I want to discuss about the budget and timeline in detail. Best regards. Yaroslav
