FYI: Tesla Model 3 and Model Y owners can easily add a traditional gauge cluster with this cost-effective DIY project using an ESP32 board and OBD adapter.
How to Add a Driver Display to Your Tesla Model 3 or Model Y
Tesla’s Model 3 and Model Y are renowned for their minimalistic design, which includes the absence of a traditional instrument cluster. All essential driving information is integrated into the central touchscreen. However, some drivers miss the convenience of having a gauge cluster right in front of the steering wheel. While many aftermarket solutions are available, MrDIY offers a simple, budget-friendly, DIY project that provides a small driver display in front of the wheel.
The DIY Solution
This project aims to satisfy those yearning for a conventional gauge cluster without compromising Tesla’s sleek design. The solution utilizes an ESP32 board that wirelessly receives data from an OBD adapter. The display setup gets its power via a USB cable, while data is transmitted solely over the air. This design ensures that the display turns on and off with the vehicle, waking up instantly as the EV powers up.
Project Components
To execute this project, you’ll need:
- ESP32 board for processing.
- OBD adapter for data collection.
- Small display screen for visual output.
- USB cable for power.
- 3D-printed case for both the display/board combo and the OBD adapter.
- Double-sided tape for securing the display to the steering column.
Display Features
The information displayed mirrors that shown on Tesla’s main screen but includes only the essentials:
- Speed
- Current gear
- Remaining range
- Icons for open doors and other alerts
Additionally, the display includes a dark mode for reduced glare during night driving.
Setting Up
Even if you’re not familiar with coding, setting up this display is straightforward:
- Purchase all necessary components from online platforms like eBay or AliExpress.
- Flash the provided software through a simple web interface.
- Assemble and install everything in your vehicle.
Cost and Benefits
The total cost for this project remains under $150, making it an affordable alternative to most aftermarket solutions. The screen’s instant boot-up is a significant advantage compared to other Android-based units, often plagued by slower start-up times.
Conclusion
This DIY project offers Tesla Model 3 and Model Y owners an easy, cost-effective way to add a traditional gauge cluster, enhancing driving convenience and vehicle aesthetics.
