Devo trasformare la MicroUSB di un Teensy 4.1 in un’interfaccia USB-C completa, aggiungendo la ricarica dell’Host tramite Power Delivery. Il circuito che immagino monta: • 1 MicroUSB male verso il Teensy (Device) • 1 USB-C female per l’alimentatore esterno • 1 USB-C female per collegare l’Host Obiettivi funzionali – Il Teensy continua a gestire i dati come Device. – Il circuito negozia su CC linee per farlo risultare Power Source e fornisce 5 V / 3 A all’Host usando l’alimentazione proveniente dall’altra porta USB-C. – Protezione da inversione, monitor corrente/tensione e corretta gestione dei cavi flip-able. Cosa mi serve da te 1. Schema elettrico completo (formato EasyEDA) comprendente: • PD controller o soluzione equivalente per pubblicizzare 5 V 3 A • Power-path, FET di commutazione, protezioni e fusibili • Connessione CC1/CC2, resistori pull-up / pull-down corretti 2. Bill of Materials dettagliata con codici produttore e footprint consigliati. Plus graditi (non obbligatori) – Note di layout PCB per evitare EMI e cadute di tensione. – Consigli su componenti facilmente reperibili in EU. Parto da zero: non possiedo alcuno schema, solo l’idea sopra. Cerco quindi un progetto solido, chiaro e replicabile che io possa poi trasformare in PCB.

Salve, sono un ingegnere di sistemi embedded con oltre 16 anni di esperienza nella progettazione elettronica, USB-C, gestione dell’alimentazione e sviluppo di prodotti completi dal concept alla produzione. Posso realizzare in EasyEDA uno schema solido e replicabile per mantenere il Teensy 4.1 come USB Device, alimentando contemporaneamente l’Host a 5 V/3 A dalla seconda porta USB-C. Definirò correttamente CC1/CC2 per entrambi gli orientamenti del cavo, power-path e MOSFET, protezione da inversione e sovracorrente, fusibile, monitoraggio di tensione/corrente e prevenzione dei ritorni di alimentazione verso Teensy o alimentatore. Includerò una BOM completa con codici produttore, footprint e preferenza per componenti reperibili in UE, oltre a note pratiche per layout, caduta di tensione, dissipazione ed EMI. Prima di finalizzare vorrei verificare il tipo di alimentatore USB-C previsto e se l’Host richiede un vero contratto PD oppure accetta la pubblicizzazione Type-C da 3 A a 5 V. Posso anche supportare la successiva revisione PCB e l’eventuale firmware di monitoraggio. Please contact me to discuss details.

Hi there, I carefully reviewed your requirement to convert the Teensy 4.1 MicroUSB connection into a USB-C host-facing interface while preserving USB data and providing a protected 5 V / 3 A power path from a separate USB-C power input. I am a mechatronics engineer with almost half a decade of experience in embedded electronics, USB interfaces, power supplies, protection circuitry, hardware prototyping, and PCB design using Altium Designer. My background is directly relevant to the USB data routing, CC1/CC2 configuration, power-path switching, current/voltage monitoring, and protection architecture required for this design. Because USB interfacing and power electronics are already part of my core skillset, I can approach the architecture efficiently and provide a clear schematic, component selection, BOM, and practical layout guidance. My primary EDA tool is Altium Designer, so if native EasyEDA files are mandatory, I would like to confirm that requirement before starting. Please send me a message so we can discuss the project and start. Best regards, Samuel tshibangu

Hello, I can design this from scratch in EasyEDA, including the complete USB-C power/data architecture rather than just adapting the existing MicroUSB connection. I would structure the design around: * MicroUSB male → Teensy 4.1 USB Device data connection * USB-C Power Input with proper CC/Sink configuration * USB-C Host output configured as a 5 V / 3 A Source * USB-C PD/CC controller and power-path management * Load switch / back-to-back FET protection and current limiting * Input/output protection, fuse, reverse-current protection and TVS where appropriate * CC1/CC2 handling for reversible USB-C cables * Voltage/current monitoring * Complete BOM with manufacturer part numbers and recommended footprints I’ll also take care of the USB-C power-path behavior carefully so the external supply can power the Host without interfering with the Teensy’s USB Device data path. I can provide the EasyEDA schematic, production-oriented BOM, and PCB layout recommendations including high-current routing, grounding, decoupling and EMI considerations. I’ll select components that are realistically available through suppliers such as DigiKey/Mouser and suitable EU alternatives. Since you’re starting from the concept only, I can develop the architecture and schematic from the ground up and make it ready for PCB implementation.

Hi, I have experience designing USB-C, embedded power, and mixed-signal hardware with protected rails from 1.1 V to 48 V, including native USB data paths, load switching, current sensing, and power-path control. I have completed boards with 10+ protected interfaces, USB-C routing, BOM/MPN control, and manufacturing-ready schematic/PCB documentation. Approach ✅ I will define the USB-C power/data roles so the Teensy remains the USB Device while the adapter safely sources 5 V/3 A to the Host from the external USB-C supply. ✅ I will design the CC1/CC2 logic, source advertisement/PD controller, backfeed-blocking MOSFETs, current/voltage monitoring, fuse/OVP/ESD protection, and flip-cable handling in EasyEDA. ✅ I will verify VBUS current capability, connector losses, USB data routing, thermal margin, and provide a detailed BOM with EU-available parts plus PCB layout/EMI guidance. Questions ✅ Must the external USB-C input accept only 5 V, or should it negotiate higher PD voltages and regulate them down to 5 V/3 A? ✅ What USB mode/speed does the Teensy connection require, and does the Host port need USB 2.0 data only or any USB-C alternate-mode support?

This project needs careful USB-C/PD and power-path design—the key is making the Teensy remain a USB Device while safely presenting the second USB-C port as a powered Host connection. I can develop the complete architecture from scratch in EasyEDA, covering the USB data routing, USB-C CC1/CC2 handling, 5 V/3 A PD source negotiation, power-path switching, reverse-current protection, current/voltage monitoring, over-current protection and fuse selection. The deliverable would include a production-oriented EasyEDA schematic plus a detailed BOM with manufacturer part numbers, package/footprint recommendations and EU-available alternatives. I can also document the critical PCB layout considerations around high-current paths, CC/USB signals, grounding, EMI and voltage drop. I’d first establish the exact USB-C role and power-flow behaviour for both ports, then select the PD controller and protection architecture around those requirements rather than forcing a generic USB-C circuit into the design. Send me the Teensy 4.1 connection constraints and your preferred PCB dimensions, and I can start with the schematic architecture. Best Regards, Sumit Kumar.
