PCB Design in EasyEDA: ESP32-PICO-D4 base board with 2 sensor inputs, SD card, and expansion headers

Budget: $10 - $30

I am enclosing the technical specifications in two languages: Russian and English. Прилагаю техническое задание на двух языках: русский и английский

Need an experienced PCB designer to create a schematic and layout for a base board based on ESP32-PICO-D4. Key features: • ESP32-PICO-D4 • Power supply: 5V–14V input with over-voltage protection and reverse polarity protection • 2x JST connectors for external sensors (5V logic, pulse input) • 3x status LEDs, reset button • microSD card slot (SPI) • Two mezzanine connectors for future expansion (16+ pins and 10+ pins) with free GPIOs routed Deliverables: Schematic, PCB layout (Gerber), BOM with MPN, Pick and Place, 3D STEP file, pinout description. Preferred tool: EasyEDA. Full specification is attached. Please include in your proposal: • Experience with ESP32-PICO-D4 (examples) • Suggested layer count (2 or 4) and reasoning • Proposed DC-DC converter model
