I have a working concept for an E-Rickshaw diagnostic tool based on an ESP32 DevKit V1, and I now need a production-ready 2-layer PCB. All circuitry must operate from the vehicle’s 48 V line, stepped down via an LM2596. The board will drive an I2C OLED, measure battery voltage, and sense individual lines for the horn, headlight, indicators, brake light, and reverse buzzer. Two probes (A & B) are included for quick continuity tests. Good engineering practice is mandatory: reverse-polarity, fuse, TVS and general input protections must be designed-in. Preferred workflow • KiCad is my first choice; if you feel EasyEDA delivers clear advantages, let me know. • Layout decisions should favour ease of assembly over sheer compactness or extra thermal tricks. • Blueto...

Please note: Max payment for this is $180. Please do not bid and then negotiate higher price if this is not acceptable. I need a KiCad project that lays out a compact, dual-rail power supply capable of delivering up to 10 A per rail at a maximum of 70 V. The board will sit inside an audio amplifier chassis and will be fed by a toroidal transformer, so low noise and a clean ground scheme are critical. Core requirements • Dual CRC-filtered rails with the 0 V reference converging only at the final capacitor. • A single pair of screw terminals at the board edge for each secondary winding so wiring from the toroid stays short and tidy. • Support for a 5020-class diode bridge (through-hole) plus an alternate footprint that lets me mount the bridge directly to the chassis v...

I already have a batch of 2.1-inch round 360 × 360 GC9B72 TFT panels from and now need the electronics and software ecosystem that turns them into a re-configurable display wall. Think 3 × 3, 4 × 4, 5 × 5, 6 × 6—or even larger—matrices where each module clicks together, powers up, and appears as one continuous canvas. Hardware • Design a compact PCB for each display that carries its own driver, power conditioning and a Wi-Fi-enabled microcontroller so every tile can auto-discover its neighbours. • Provide an edge connector or other simple bus so power and data can daisy-chain when the tiles are slotted into a frame. • Supply full schematics, BOM and Gerber files, plus a reference back-plane/controller if you feel a master nod...

I already have a KiCad v10.4 design exported to Gerber and will share the schematic, PNG layout images and an initial BOM. What I need now is a careful re-work so the board prints flawlessly on a Voltera V-One. Here is the scope in plain terms: • Import my existing Gerbers, then modify and optimise them for a 2" × 3" FR1 board. • Advise whether the plated holes should be drilled for 1.0 mm or 0.4 mm copper rivets and implement the correct drill table. • Provide full design assistance: refine component selection and placement, reroute traces for cleaner paths, and add or remove small features where that improves manufacturability or current handling. • Keep all components at least 0.4 in from each corner; the corner mounting holes themselves are n...

I need a working human-computer interface that can both pick up and broadcast data over Bluetooth at the highest speed the protocol allows. The data flowing through it will be full-rate cellular communications data rather than simple audio or text, so throughput and low latency are critical. On the input side the unit will read Qi energy and Acu-meridian energy via harness-style skin contacts. Those raw sensor signals have to be conditioned, digitised and pushed straight to a tablet over Bluetooth without noticeable lag. In the opposite direction the tablet will be able to transmit control or stimulation patterns back to the interface just as quickly. The job covers hardware design, embedded firmware and a basic demo app for a tablet or computer: • Hardware: schematic, PCB layout an...

Please Note: total amount is $80. Please do not bid if this is not acceptable. I’m putting together a single-rail power supply for sensitive audio gear and need a clean, hum-free output. The brief is straightforward: • Topology: prefer an LDO-based regulator front-ended by a capacitance-multiplier stage (or an equally quiet alternative you can justify). • Input: board-mounted, fully encapsulated transformer—no off-board or open-frame types. • Output: 9 V to 24 V DC, up to 1.5 A continuous. Low ripple and broadband noise filtering are far more important than absolute efficiency. Include transformer snubbers. • Target use: high-end audio equipment, so 50/60 Hz mains-borne noise, switch-spikes and thermal drift must all be kept to a minimum. Deliverable...

I’m building a compact, 4–6-layer mixed-signal board that will sit at the heart of a new sensor-interface product. The board must collect analog data, run it through an on-board DSP, and then push results out over Wi-Fi, Bluetooth, and a cellular link. To keep the unit fully portable, all power must be managed through an integrated battery management system, including charging, protection, and efficient rail generation for the analog, digital, and RF domains. Here’s what I need from you, start to finish: • Complete schematic capture with full part selection, paying special attention to RF front-ends, low-noise sensor inputs, the DSP section, and the battery management circuitry. • A 4–6 layer stack-up that cleanly separates noisy digital, sensitive ana...
