I’m developing a prototype for a Smart Bin used in hospital inventory management. The bin will detect supply levels by measuring weight using load cells (with HX711), connected to an ESP32 for wireless data transmission, along with a small display for item/barcode info and stock alerts. I’m looking for an experienced PCB/IoT engineer who can: - Design a PCB schematic + layout (ESP32 + HX711 + display + power supply). - Provide a BOM (Bill of Materials) with sourcing suggestions. -Deliver Gerber/Drill files for fabrication. -Supply basic firmware (ESP32/Arduino IDE or ESP-IDF) to read load cell data and display results.
