AutoPi Mini: Plug-and-Play Fleet Telematics for Indian Fleets

Fleet Telematics Without the Complexity

Not every fleet telematics deployment requires a programmable Linux gateway with Docker containers and raw CAN frame access. Many Indian fleet operators need a simple, reliable device that plugs into the OBD-II port, connects to cellular, and starts transmitting vehicle location, trip data, and diagnostic parameters, with zero configuration and zero monthly subscription fees.

The AutoPi Mini is built for exactly this use case. Smaller than a deck of cards (67.2 x 49.6 x 25 mm, 63 grams), the Mini plugs directly into any vehicle’s OBD-II port, powers on automatically, establishes a 4G LTE Cat 1 connection via its built-in SIM (covering 188 countries), and begins transmitting data to the AutoPi Cloud platform at no recurring cost.

What the Mini Captures

Despite its compact size, the AutoPi Mini extracts a comprehensive set of vehicle parameters:

• OBD-II diagnostics: engine RPM, vehicle speed, coolant temperature, intake air temperature, fuel system status, engine load, and all standard OBD-II PIDs
• Legacy protocols: CAN, ISO 9141-2, ISO 14230-4 KWP, and K-Line support for compatibility with older vehicles
• GPS tracking: real-time location with internal antenna, trip history, and geofencing
• Accelerometer data: 3-axis accelerometer for harsh braking, rapid acceleration, and cornering detection
• EV parameters: battery state-of-charge (SoC), state-of-health (SoH), cell voltages, HV battery temperature, charging session data

The 4 samples/sec sampling rate with millisecond timestamps is sufficient for fleet management and driver behaviour analysis. For higher-resolution data acquisition (100 samples/sec, raw CAN frames), the TMU CM4 or CAN-FD Pro are the appropriate choices.

EV Fleet Monitoring

The AutoPi Mini is particularly capable for electric vehicle fleet management, a growing segment in India as logistics companies, ride-sharing platforms, and last-mile delivery services electrify their fleets. The Mini tracks EV-specific parameters including battery SoC, minimum and maximum cell voltages, available power and energy, HV battery temperature, and charging patterns.

For fleet operators managing mixed ICE and EV fleets, the Mini provides a single device and single dashboard that covers both vehicle types. EV-specific insights, charge scheduling optimisation, battery degradation tracking, range estimation accuracy, sit alongside traditional fleet metrics like trip distance, idle time, and driver scoring.

AutoPi Cloud: Zero Subscription

The AutoPi Cloud platform is included at no monthly subscription cost. Fleet managers access:

• Live tracking: real-time vehicle positions on a map with speed, heading, and status indicators
• Trip history: automatic trip detection with start/end locations, distance, duration, and idle time
• Geofencing: configurable geographic zones with entry/exit alerts
• Vehicle health: DTC (Diagnostic Trouble Code) monitoring with check-engine light alerts
• Driver scoring: behaviour analysis based on acceleration, braking, cornering, and speed patterns
• REST API: programmatic access for integration with existing fleet management or ERP systems

Deployment Considerations for India

The AutoPi Mini’s built-in SIM with roaming across 188 countries simplifies deployment logistics. For Indian fleets operating across multiple states and cellular networks, the embedded connectivity eliminates the need to source, provision, and manage separate SIM cards.

Operating temperature range of -40 to +85 degrees Celsius covers the full spectrum of Indian climate conditions, from Ladakh winters to Rajasthan summers. The 170 mAh backup battery maintains GPS tracking briefly after vehicle power is cut, useful for theft detection and unauthorised movement alerts.

For fleets where vehicles cross into Nepal, Bangladesh, Sri Lanka, or Myanmar, the multi-country SIM coverage means the same device continues operating without reconfiguration. Long-haul transport fleets moving goods across South Asian borders benefit from cross-border tracking.

When to Choose the Mini vs TMU CM4

Requirement	AutoPi Mini	TMU CM4
OBD-II parameter extraction	Yes	Yes
Raw CAN frame access	No	Yes (SocketCAN)
CAN-FD support	No	Yes (dual channels)
Edge computing (Docker)	No	Yes
Custom sensor integration	No	Yes (HAT header)
Cellular	4G LTE Cat 1	4G LTE Cat 4
Sampling rate	4/sec	100/sec
Form factor	Compact dongle	OBD-II dongle (larger)

Choose the Mini for straightforward fleet management, tracking, diagnostics, driver behaviour, EV monitoring, where simplicity and zero configuration are priorities. Choose the TMU CM4 when you need raw CAN access, edge computing, custom sensor integration, or high-resolution data capture.
