IoT Board

This project is an IoT board designed specifically for capturing and processing vehicle telemetry data crucial for safe driving and vehicle maintenance.

Key Specifications

• Processor: ATmega2560 Microcontroller

• Operating Voltage: 5V

• Connectivity: CAN Bus, LTE (SIM800L), GPS, Bluetooth, Wi-Fi (ESP8266-style), UART, I2C

• Sensor Support: The board is specified to support an Inertial Measurement Unit (IMU), Accelerometer, GPS, Temperature Sensors, Ultrasonic Sensors, and more.

The board is designed as a central hub for in-vehicle data acquisition and communication.

• Processing: At its core is the ATmega2560 MCU, which provides ample processing power and I/O for managing the various peripherals. It features 54 digital I/O pins and 16 analog pins.

• Vehicle Integration: A CAN transceiver allows the board to connect directly to a vehicle’s CAN bus, enabling it to read diagnostic data like speed, RPM, and engine fault codes.

• Location & Communication: An LTE/GSM module provides a cellular link for transmitting data to a remote server, while a GPS module provides precise location tracking. The board also supports Wi-Fi and Bluetooth for short-range wireless communication.

• Power Management: It includes power management, including a 4V buck converter and circuits for battery charging and protection, allowing it to operate independently or on battery backup.
