Build a USB Power Monitoring Device (ESP32 + INA219 + OLED)

Title: Build a USB Power Monitoring Device (ESP32 + INA219 + OLED)

Description:

I am looking for an embedded systems developer to build a working prototype of a USB power monitoring device.

The device should:

- Measure Voltage (V), Current (A), and Power (W)
- Display values in real-time on a small OLED screen
- Work as a pass-through (input power → device → output to phone/load)

Preferred components:

- INA219 (or similar current/voltage sensor)
- ESP32 / Arduino
- 0.96” OLED display (I2C)

Deliverables:

- 1 fully working prototype (hardware)
- Clean and working source code
- Circuit diagram / wiring schematic
- List of components used

Nice to have (optional):

- Compact design
- Basic enclosure (3D printed or simple casing)

Budget:
Open to proposals (expected ₹1,000 – ₹2,000 depending on experience)

Timeline:
1–2 weeks

Please include:

- Similar projects you have worked on
- Your approach to building this device

Only apply if you have experience with Arduino/ESP32 and sensor integration
