I’m putting together a tiny, sensor-less “mouse” that behaves as a USB HID device but only needs left-click, right-click and scroll-wheel input—no cursor movement at all. All three inputs live off-board: two OMRON D2F-01F microswitches and a rotary wheel/encoder that can be unplugged from the board. The board itself carries nothing more than the USB-C port, the MCU and the supporting passives, so I want the footprint kept as compact and component-clustered as practical. Here’s what I need from you: • Complete schematic built around a readily available USB-capable MCU (I’m flexible—SAMD21, STM32, EFM8 or anything else that cleanly delivers 5 V bus-power and native HID). • Two through-hole or JST headers for the switch leads plus one fo...

I’m building a smart-home device that tracks and optimises household energy use, and I need a seasoned IoT engineer to transform the concept into a production-ready printed circuit board. The board must combine a low-power microcontroller, several sensors for real-time measurements, and a wireless module for seamless home-network integration. You’ll be responsible for the full hardware path: selecting the right components, creating the schematic, laying out a compact multi-layer PCB, and making sure everything plays nicely with typical smart-home power rails. Signal integrity, thermal performance, and antenna placement are critical because the unit will sit inside a small plastic enclosure. To keep things clear, here’s what I expect as final hand-offs: • Complete...

I’m building a small-footprint “Macho” voice-assistant board and need a complete hardware package created in EasyEDA. The core is an ESP32-WROOM-32 (38-pin dev board) paired with a 0.96" I²C OLED, an INMP441 I²S microphone, and two TTP223 touch sensors. I’d also like a row of additional GPIO headers for future expansion. Scope of work • Draw the full schematic, matching the real-world pinouts of every off-the-shelf module so that each one can drop onto male headers on the PCB without re-soldering. • Produce a compact PCB layout that keeps the overall footprint as small as practical while maintaining sensible routing for I²C and I²S lines. • Deliver manufacturing files: Gerbers, BOM, and Pick-and-Place data. • Opt...

I’m finishing the dashboard for a very small street-legal minicar (overall body 52" x 125") and need three matching, custom-built gauges: • 4" electronic speedometer, 0-85 mph, with integrated odometer and tripometer (digital) • 4" electronic tachometer, 0-8,000 rpm, visually identical to the speedo, for a 999cc v-twin engine • Fuel level gauge in the same style All three share a black face, crisp white lettering and a fixed amber backlight (there is a chance I may decide on white instead, but I do not want user-adjustable colors). The font should evoke the look of a 1985 Ford Tempo while steering clear of any elements that could infringe on Ford’s design rights. Diameter tolerance must allow them to drop cleanly into a 4" panel open...

Your role is to verify that every board we release aligns with ISO requirements while guiding us on best-practice layout decisions inside Altium and OrCAD. The boards you will review carry several hundred volts, so I’m particularly interested in your insight on: • Creepage and clearance rules • Selecting and specifying insulation materials • Designing for reliable voltage-withstand testing results Beyond the high-voltage layer stack, you should be comfortable auditing layouts that include SPI and CAN interfaces. If you can spot signal-integrity issues or routing pitfalls in those channels before we commit to fabrication, that’...

I need a compact, microcontroller-based gateway that sits in-line on a CAN-FD bus and removes or forwards diagnostic frames according to rules I supply. The core of the design should be a device with native CAN-FD support (an STM32, S32K, dsPIC33 C, or any equivalent you recommend) paired with a standard FD-capable transceiver so the board can operate at 500 kbps arbitration and 2 Mbps data rates without external glue logic. Beyond the hardware, I also require firmware—written in C or C++—that initialises the peripheral, listens for every frame, and applies real-time ID filtering (e.g. allow 0x700–0x7FF, block all others). Filter rules must be easy to change over UART or USB so I can refine them in the field. Deliverables • Schematic, PCB layout (Gerber/ODB++),...

The objective of this project is to design Kicad general-purpose IoT controller based on the ESP32-C6-WROOM-1U. The board is intended for external environmental mounting and requires specific design considerations for humidity resistance and high-voltage safety. The primary layout constraint is to maintain the smallest possible footprint within a 38mm x 100mm maximum area.

Mon design PCB est déjà placé et routé, mais, avant de lancer le prototype, je veux m’assurer qu’il est vraiment prêt.

I have already chosen the core components for a compact mixed-signal board that will consolidate several sensors—a barometric pressure sensor, a nine-axis IMU, a GPS/GNSS receiver, and a simple power-status monitor—into one surface-mount module along with a controller chip. Your task is to translate those parts into a complete schematic, turn the design into an SMD-friendly PCB, and run thorough simulations so I can be confident in its behaviour before we move to prototypes. The board’s sole purpose is sensor integration, so clean routing between the analogue front-end, digital lines, and any required power-conditioning blocks is critical. I’m comfortable if you work in Altium, KiCad, or another mainstream CAD package, as long as the final files are ready for fab...

I’m putting together a microcontroller-based inverter for industrial equipment and need an engineer to translate my specs into a production-ready design. The goal is a rock-solid 300 W pure sine wave output, stepping from a nominal 350 V DC input down to 200 V AC. Low total harmonic distortion is essential because the unit will drive sensitive industrial controls. You are free to choose the MCU family you’re most comfortable with (STM32, PIC, MSP430, or similar) as long as the firmware is well-documented and the control algorithm delivers a clean sinusoid under varying loads. Efficiency, thermal performance and fault handling must be considered throughout the design. Deliverables • Complete schematic in Altium, KiCad or Eagle • PCB layout files ready for fabricati...

Regulatory or environmental compliance is not required at this stage. • select whatever benches, scopes, thermal cameras, or test...

I need a straightforward PCB laid out that lets me drop-in one electromechanical relay where my existing board is laid out for another. The task is purely mechanical/electrical adaptation—no signal conditioning or extra components—just clean, reliable pin-to-pin routing so I can “hot-swap” the two relay footprints without touching the main board. Both the Omron G6K-2F-Y DC5 and the Teledyne 712D-5/G are electromechanical relays. Unlike solid-state or reed relays, they use an electromagnetic coil to physically move mechanical contacts to switch circuits. Specifically, they are classified as: Low Signal / Telecom Relays: Designed for switching low-level signals (typically up to 1A). DPDT (Double Pole Double Throw): Both have a "2 Form C" contact arrange...
