48V E-Rickshaw Diagnostic PCB Design

Descripción de la oferta
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. • Bluetooth must support both BLE and Classic modes for broad phone compatibility. Deliverables • Complete schematic • PCB layout + Gerber set • BOM and Pick-&-Place (CSV or XLSX) • All KiCad (or agreed equivalent) source files • Annotated component values, footprints, and fabrication notes ready for board house upload Acceptance I will run a design review, order prototypes, and perform bench tests. Minor post-prototype tweaks are part of the scope; anything beyond that will be a new milestone. Provide clear silkscreen labels and test points so future service engineers can navigate the board easily. If this matches your skill set in power-aware ESP32 designs, let’s get started.
