Design a Low-Cost Automotive 4G LTE Telematics PCB for Fleet Management & FASTag Platform (Complete Hardware Design)
Budget: ₹1,500 – ₹12,500 INR
Project Overview
I am developing a commercial automotive telematics device for the Indian market. The product will be used for fleet management, GPS tracking, vehicle diagnostics, driver behavior monitoring, and future FASTag ecosystem integration.
This is **NOT** a hobby or Arduino-based project. I require an industrial-grade PCB design that can be manufactured in China through PCBWay, JLCPCB, or a similar PCB assembly service.
The final deliverable should be ready for prototype manufacturing and later mass production.
I am looking for an experienced hardware engineer or embedded systems engineer who has previously designed automotive telematics devices, GPS trackers, CAN bus products, IoT hardware, or vehicle diagnostic devices.

# Objective
Design one universal hardware platform that supports:
* Passenger cars
* SUVs
* Commercial vehicles
* Trucks
* Buses
* Construction equipment
* Agricultural vehicles
The same PCB should support different cable harnesses rather than different PCB designs.
---
# Functional Requirements
## Communication
* 4G LTE (Cat-1 or Cat-1 bis preferred)
* Nano SIM
* Optional eSIM support
* MQTT
* HTTPS
* TCP/IP
* OTA firmware update capability
* Secure firmware architecture
---
## GNSS
Must support:
* GPS
* NavIC (Indian Navigation System)
* GLONASS
* Galileo
* BeiDou
* QZSS (optional)
Fast satellite acquisition and good urban performance are preferred.
---
## Vehicle Interfaces
The PCB shall support:
* OBD-II (16-pin connector)
* SAE J1939 (9-pin Deutsch connector)
* CAN 2.0A
* CAN 2.0B
* ISO15765
* UART
* SPI
* I²C
* USB programming interface
The design should use interchangeable cable harnesses so the same PCB works on different vehicle types.
---
## Vehicle Parameters
The hardware should be capable of supporting:
* Ignition status
* Engine RPM
* Vehicle speed
* Odometer
* Battery voltage
* Charging voltage
* Fuel level
* Fuel consumption
* Engine coolant temperature

* Engine hours
* VIN
* Diagnostic Trouble Codes (DTC)
* Driver behaviour
* Harsh braking
* Harsh acceleration
* Harsh cornering
* Crash detection
* Geofence support
* Idling detection
* Overspeed
* AC ON/OFF status where available through CAN or configurable digital input
---
## Bluetooth
Bluetooth 5.x support for future accessories:
* Wireless fuel sensor
* Driver ID
* Temperature sensor
* BLE beacon
* Tire pressure monitoring (future)
---
## Sensors
Include support for:
* 3-axis accelerometer
* Optional gyroscope
* Internal temperature monitoring
* Backup battery monitoring
---
## Inputs & Outputs
Include:
* Ignition input
* Door input
* SOS button
* Digital inputs
* Digital outputs
* Relay output for engine immobilizer
* LED indicators
* Buzzer output
* Analog input
---
## Power Supply
Automotive-grade design supporting:
* Wide input voltage (minimum 9–36V)
* Reverse polarity protection
* Over-voltage protection
* Under-voltage protection
* Load dump protection
* Automotive transient protection
* ESD protection
* Low power sleep mode
* Backup battery charging
---
## PCB Requirements
* Compact PCB
* 4-layer PCB preferred (or justify 2-layer if feasible)
* Optimized for low-cost manufacturing
* Automotive-grade design practices
* Easy assembly
* Design for manufacturability (DFM)
* Design for testing (DFT)
---
# Cost Target
This is an important requirement.
Target production quantity:
* Initial production: 200 units
* Future production: 5,000+ units
Target hardware BOM:
Approximately USD 25–30 per device.
Please prioritize cost optimization while maintaining reliability.

3. Gerber files
4. Bill of Materials (BOM)
5. Pick and Place (Centroid) files
6. Assembly drawings
7. PDF schematic
8. Manufacturing notes
9. Design files (KiCad or Altium preferred)
10. Connector pinout documentation
11. Power architecture documentation
12. Programming connector documentation
13. Prototype bring-up guide
14. Basic hardware testing procedure
---
# Intellectual Property
All design files, schematics, PCB layouts, manufacturing files, and documentation must become my exclusive property upon project completion.
The design must not be reused, resold, or shared with any third party.
