Clinical ECG ESP32 Development
Description
Budget: $10 - $30
Title: Embedded Hardware & Firmware Engineer for ECG Device (ESP32, BLE, PCB Design)
Project Description:
We are developing a portable multi-lead ECG device and are looking for an experienced embedded engineer (or small team) to support hardware design and firmware development for our first working prototype.
This is a from-scratch development project (not cloning any existing product). We may take high-level reference from existing ECG devices, but the design, firmware, and implementation must be original.
Project Scope:
1. Hardware Design
- ECG circuit design (low-noise analog front-end)
- Component selection (preferably medical-grade or equivalent)
- Microcontroller integration (ESP32 preferred)
- Power management (Li-ion battery + charging)
- BLE connectivity design
2. PCB Design
- Schematic design
- PCB layout
- Gerber file generation
- BOM finalization
3. Firmware Development
- ESP32 firmware development
- BLE communication (device ↔ mobile app)
- Real-time ECG data acquisition
- Data packet transmission
- Basic power management (sleep mode, battery monitoring)
4. Prototype Support
- Assist in debugging after PCB fabrication
- Support 1–2 iteration cycles if required
Key Requirements:
- Experience with embedded systems (ESP32 or similar MCU)
- Strong experience in PCB design tools (Altium / KiCad / Eagle)
- Understanding of low-noise analog circuits (important for ECG)
- Experience with BLE communication
- Ability to work with real-time signal data
Highly Preferred:
- Experience in ECG / biomedical / wearable devices
- Familiarity with ECG ICs (ADS1292 / ADS1298 or similar)
- Experience building end-to-end embedded products
Deliverables:
- Complete schematic design
- PCB layout + Gerber files
- Final BOM
- Working firmware (source code included)
- Basic documentation
Budget & Timeline:
- Fixed Budget: $2000 (Milestone-based)
- Timeline: 4–6 weeks for first working prototype
Important Notes:
- This is a serious product development project, not a basic Arduino-level task
- We are looking for experienced engineers only (not beginners)
- All deliverables must include source files and full ownership
Screening Questions (Mandatory):
- Have you worked on any ECG or biomedical device before?
- Which PCB tools do you use?
- Have you worked with ESP32 + BLE in real-time applications?
- How would you approach low-noise ECG signal design?
- Can you share any similar past work or portfolio?
