I need a seasoned power-electronics engineer to take my concept for a small, isolated flyback switching power supply and turn it into a production-ready design for a consumer-electronics product. The supply must accept 230 V AC nominal but remain stable across the full universal range of 85–265 V AC. On the secondary side I want three rails—12 V, 5 V, and 3.3 V DC—sharing roughly 3–4 W total. Exact current splits can wait until you help me finalise the power budget. Compact size is the top priority, so I expect smart component selection, tight transformer design, and a PCB layout that keeps both footprint and height to an absolute minimum while still meeting creepage, clearance, and EMI/EMC requirements. Although efficiency and low standby losses matter (this will ...

I have a batch of 51-100 boards that need careful through-hole soldering, plus a small run of matching wire harnesses and a few damaged PCBs that require touch-up repair. All components are already sourced and labelled; I simply need steady-handed assembly and inspection so everything leaves my shop fully functional. You’ll be working with both through-hole parts and SMD repairs down to 0603 size, so solid joint quality, clean lead trimming, and consistent flux cleanup are vital. After soldering, each board must pass a quick continuity and visual check before you move on to the next. The wire harnesses are straightforward crimp-and-solder leads that plug directly into these boards, and I’ll provide the pin-out diagrams. Deliverables: • 51-100 fully soldered, tested throu...

I need a clear, production-ready schematic that lets me vary the speed of a DC motor smoothly and repeatably. The goal is a stand-alone circuit I can hand straight to my PCB team or prototype on a breadboard without extra guesswork. Here is what I’m after: • A complete schematic showing every component and connection required for precise speed control of a single DC motor. • A concise Bill of Materials with component values, part numbers, and readily available footprints. • Any design notes that explain how the circuit regulates speed and protects the motor (e.g., soft-start, over-current safeguards, thermal considerations). • Optional but welcome: a quick LTspice, Multisim, KiCad, Altium, or Eagle file so I can simulate or drop the design into my layout ...

My current KiCad 10 board is designed, but the differential traces that connect the DSP to the external SDRAM are not length-matched or impedance-controlled. I need the layout reviewed and re-routed so those critical nets meet the timing budget of the processor. Scope • Analyse the existing PCB to identify every DSP↔SDRAM signal that exceeds length or impedance targets. • Re-route or tune the traces inside KiCad so data, address, and control lines are matched within the manufacturer-specified tolerance. • Adjust layer stack-up, via strategy, or termination as required to achieve 50 Ω single-ended / 100 Ω differential (or the closest feasible value based on the current stack-up). • Update the constraints in the KiCad design rules so future edits...

I have a custom board built around the STM32G031 and I want a clean, production-ready firmware project created in C with STM32CubeIDE. Your first task is to bring the microcontroller to life: set up the system clock, configure the required GPIO pins, verify the build, and program the device. Here is the scope I need covered: • Create a CubeIDE project that targets STM32G031, using either HAL or direct LL drivers where it makes sense. • Configure clock tree (HSE, HSI or internal PLL as required) so the MCU runs at the specified operating frequency. • Initialise all GPIOs I mark on the schematic; direction, speed and pull settings must match the hardware design. • Build, generate the .hex/.bin files and flash them onto the board through ST-Link over SWD. • ...

1. Project Overview & Architecture The goal of this project is to design a set of modular, decentralized expansion PCB boards for grow tent automation. Instead of a rigid central mainboard, each expansion board functions as an independent node powered by a localized ESP32-C3 Supermini module, communicating via Wi-Fi/MQTT through ESPHome into Home Assistant. To reduce clutter and eliminate the need for multiple external power supplies, all boards will share a common power distribution concept: 12V DC Input (via standard 5.5x2.5mm barrel jacks or terminal blocks) with onboard step-down regulation (e.g., Buck converters) to supply 5V and 3.3V where needed, allowing a single 12V barrel power supply to be daisy-chained across boards. 2. General Requirements for All Boards Microcontroller: ...

A compact double-layer board in one of my units has started to misbehave and, unfortunately, the original CAD files are long gone. I still have a clean schematic with every part ID called out, so the information is there—it just needs to be turned back into a full set of manufacturing data so I can isolate and fix the fault. Here’s what the assignment entails. I will provide high-resolution photos of both sides of the board together with the schematic. Trace the copper, match every net to the schematic, and rebuild the layout exactly as it sits today. Deliverables: • Editable schematic aligned with the physical board • Fault-analysis notes pointing to likely trouble at power input Freelancers are required to provide a budget estimate based on images supplied. Once ...

Complete Layout review of a 12 Layer PCB

Status: Schematic is finalized — layout work only (with expert schematic/BOM review). Project Overview I need an experienced PCB designer to create the PCB layout for a small precision encoder module with Bluetooth Low Energy (BLE) connectivity. The complete electronic schematic and BOM are already defined; your task is the board layout, design review, and preparation of full manufacturing data. A schematic review is required to confirm correctness before placement begins. Board Architecture: The board contains two functionally independent sections, which must be physically separated to avoid mutual interference: - Encoder section: STM32G474 microcontroller and its supporting peripherals, two AM26LV32E differential line receivers and ESDA6V1SC6 ESD protection device. - Bluetooth se...

I have an ESP32-based circuit fully wired and documented in a handful of clear .png images. What I need now is a clean KiCad project that turns those pictures into a proper electronic schematic and a ready-to-fabricate PCB layout my daughter can actually build and use for her college assignment. All the parts, net names, and pin connections are already settled in the images, so there is no component selection or electrical guesswork—just accurate translation into KiCad. Because the board will be assembled and deployed, please route it as a real-world, functional design rather than a classroom illustration. Standard IPC constraints aren’t mandatory; feel free to apply your usual good-practice defaults unless you spot something that obviously improves manufacturability or reli...

A complex, minimum 4-layer board needs to be taken from concept to production-ready files using EasyEDA Pro. I already have the preliminary schematics and key mechanical constraints; the task now is to translate them into a clean, reliable layout that respects enclosure clearances, power integrity, and high-speed signal rules. You will be working with mixed-signal nets, power electronics sections, and several custom parts that come only with datasheets, so footprint creation and library hygiene are critical. Proper plane splitting, controlled-impedance routing, ground strategy, and EMI/EMC-conscious placement all matter just as much as meeting the mechanical outline I will supply. Regular progress snapshots—whether via EasyEDA’s share link or exported PDFs—keep us align...
