Build Your Own Car Dashboard with Raspberry Pi is a step-by-step e-book that takes you from a blank Raspberry Pi to a working in-car dashboard displaying live OBD2 data, custom gauges, and fault codes — all built with Python and under $50 in hardware.
Every chapter is built around real, working code. No filler, no theory for the sake of it. You follow the steps, you get a result.
What you need: Raspberry Pi 3B+, 4, or 5 · ELM327 OBD2 adapter (Bluetooth or USB, ~$10–$25) · Any screen · Any OBD2 car (1996+ US, 2001+ EU). No prior Python experience required.
What You’ll Build
Live OBD2 Dashboard
Real-time RPM, speed, coolant temp, throttle position, and more — pulled directly from your car’s OBD2 port and displayed on screen.
Custom Gauge Interface
Your own digital gauge cluster, designed and rendered in Python. Styled however you want — not locked into someone else’s UI.
Fault Code Reader
Read, display, and clear DTCs straight from the dashboard. No separate scan tool needed.
Data Logging
Log every trip to SQLite. Review performance over time, track fuel data, or export for analysis.
In-Car Deployment
Auto-starts when the car turns on. Kiosk mode, power-safe shutdown, 12V wiring — everything to make it permanent.
What’s Inside
- Hardware setup — Pi OS install, display wiring, in-car power supply
- OBD2 connection — ELM327 pairing, PID basics, testing your connection
- Reading live data — python-OBD setup, polling, async streams, error handling
- Building the interface — gauge layouts, Pygame rendering, fonts and scaling
- GPIO sensors — wiring diagrams, I2C/SPI, integrating external sensors
- Fault codes — reading DTCs, freeze frame data, clearing codes
- Data logging — SQLite, trip history viewer, CSV export
- Deployment — systemd autostart, kiosk mode, power-safe shutdown
- Going further — GPS, custom alerts, Wi-Fi updates

FAQ
Do I need to know Python?
No. The book explains every line of code as it’s introduced. If you can follow instructions, you can finish this project.
Will it work with my car?
If it has an OBD2 port — yes. That’s any petrol or diesel car made from 1996 (US) or 2001 (EU) onward.
What format is it?

Sarah_M –
Good guide overall. Goes through everything step by step. I’m using a Pi 4 and it works great. The parts list was helpful so I didn’t have to guess what to buy. Took me about a weekend to get it working. Would’ve been 5 stars but some photos could be higher quality. Still worth it though.
