Developing Kicad 9.0 design for a small PCB that is used in industrial cabinets . To convert and input digital signal to a "define by trimmers" analogical output , with expansions . All the items in the specs. must be 100% respected .

I’m building a custom handheld that plays original Game Boy Advance and Game Boy Color cartridges and I need the entire internal hardware engineered for it. I will be designing and manufacturing the outer shell myself, so your focus will be everything that sits inside the case: • A reliable GBA/GBC cartridge reader is the top priority; it must boot retail carts flawlessly. • Back-lit LCD (or IPS) screen driven at the correct refresh rate with minimal tearing. • Stereo speakers plus a small on-board amplifier and 3.5 mm headphone jack. • Rechargeable battery pack with USB-C charging and power-management circuitry (fuel gauge, protection, and safe-charge IC). • Responsive D-pad, A/B + L/R buttons, Start/Select, and volume control interface routed to a ...

We are developing a luxury smart ring wearable and are looking for an experienced hardware engineer to design a compact PCB/FPC for this device. This is a very small wearable device, so experience with ultra-compact electronics is essential. Device concept: Smart ring with biometric sensors and Bluetooth Low Energy connectivity. Main components planned: • Nordic nRF5340 BLE SoC • MAX86174 optical biometric sensor (PPG) • ICM-42670 motion sensor (IMU) • TMP119 temperature sensor • nPM1304 power management IC • External SPI Flash memory • Li-Po micro battery Design constraints: • Ring thickness target: 3–3.5 mm • PCB width: approx 5.5 mm • PCB length: approx 26–30 mm semicircle layout • Extremely low power consumption ...

I look for hardware developer. Electronics schema and pcb designer.

I need the internal circuitry of the KK-82MS scientific calculator documented so I can design a drop-in replacement PCB. Your job is to open the unit, trace every relevant signal, and give me a clear map of what connects where. The focus is on both LCD behaviour and the button-scanning scheme, so I expect you to show how each LCD segment is driven, which pins act as commons, how the microcontroller multiplexes them, and the exact keyboard matrix rows and columns the processor polls. Feel free to combine a logic analyser, multimeter, oscilloscope, or any other bench tool you trust; choice of instrumentation is up to you as long as the final data are unambiguous. Deliverables • High-resolution photos of the calculator fully disassembled, including close-ups of the flex cables and IC m...

I own an original KeyMouse Track, now discontinued, and would like to bring it back to life. Reference product: Intended production size: Only for personal use at this point. However, where possible and cost-effective, design decisions should consider future scalability to larger production runs. Available artifacts: - STL Files (I don't know whether these files are suitable for manufacturing, or some earlier draft): - Assembly instructions: - Original PCB which can be purchased: - Track ball sensor module image and description: - Custom-made wrist extension CAD files: Deliverables: - Deliver cleaned and validated STL files suitable for reliably producing a functioning unit via 3D printing. with the external wrist extension integrated - Full reverse eng...
