Embedded Systems Engineer for EV Dashboard Design
Budget: ₹1,500 – ₹12,500 INR
I am looking for an experienced embedded systems engineer to design a digital instrument cluster (dashboard) for electric vehicles (2-wheeler and 3-wheeler).
## System Requirements:
### Input Signals:
* Speed input (hall sensor / controller signal)
* Battery voltage input
* Current sensing (optional but preferred)
* Brake signal
* Indicator signals (left/right)
* Reverse signal
* Ignition signal
---
## Display Requirements:
* Digital speedometer (km/h)
* Trip meter (distance)
* Odometer (total distance)
* Battery level indicator (% or bar)
* Indicator icons (left/right, high beam, reverse)
* Warning indicators (low battery, fault)
---
## Display Hardware:
* TFT LCD / IPS display (2.4” to 5” range)
* Good visibility in sunlight
* Smooth UI (no lag)
---
## Functional Features:
* Real-time speed display
* Distance calculation (trip + total)
* Battery voltage monitoring
* Fault indication display
* Startup animation / branding (optional)
* Menu/settings (optional)
---
## Communication:
* Support UART or CAN communication from controller
* Option to work with pulse-based speed input
---
## Hardware Requirements:
* Microcontroller-based design
* Stable power supply (12V → 5V / 3.3V)
* EMI-resistant design for automotive environment
* Proper filtering for noisy signals
---
## PCB Requirements:
* Compact PCB for dashboard enclosure
* Automotive-grade connectors
* Vibration-resistant design
* Easy mounting provision
---
## Firmware Requirements:
* Fast refresh rate display
* Accurate speed & distance calculation
* EEPROM/Flash storage for odometer
* Fault handling logic
---
## Mechanical:
* PCB suitable for enclosure mounting
* Suggest display mounting method
---
## Deliverables:
* Full schematic
* PCB layout (EasyEDA / KiCad / Altium)
* Gerber files (manufacturing ready)
* BOM with exact part numbers
* Firmware (mandatory)
* UI design (basic or advanced)
* Debug support after prototype
---
## Application:
* Electric scooters
* E-rickshaws
* E-loaders
---
## Goal:
Develop a reliable and scalable digital cluster suitable for commercial EV products with clear visibility and accurate data.
