The LilyGO TTGO T8 ESP32-S2 is a popular choice among developers and hobbyists due to its compact size and powerful features. Knowing its precise dimensions is crucial for project planning and enclosure design. This guide provides detailed information on the TTGO T8's physical dimensions, along with helpful tips for incorporating it into your projects.
Understanding the TTGO T8's Physical Footprint
The TTGO T8's dimensions are not universally standardized across all vendors or versions. Minor variations might exist due to manufacturing tolerances or slightly different revisions. However, the general dimensions remain consistent. We'll focus on the commonly cited measurements to give you an accurate representation.
Key Dimensions:
- Length: Approximately 25.7 mm (1.01 inches)
- Width: Approximately 21.5 mm (0.85 inches)
- Thickness: Approximately 7 mm (0.28 inches) This measurement can vary slightly depending on the specific components soldered to the board.
These dimensions refer to the board's overall footprint, excluding any protruding components like headers or antennas. It's essential to consider these projections when designing a case or enclosure.
Header Pin Considerations:
The TTGO T8 boasts various headers offering GPIO access, power connections, and more. When accounting for the physical space required, remember to add the length and width of these headers to the overall dimensions. The header pins typically protrude approximately 2mm (0.08 inches).
Practical Implications of TTGO T8 Dimensions
Understanding the TTGO T8's precise dimensions is critical in several application scenarios:
1. Enclosure Design:
Accurate dimensions are crucial for designing a custom enclosure. Knowing the exact footprint and header pin locations ensures a snug fit and prevents any interference with the board's functionality. Slight inaccuracies can lead to fit issues or damage to the board.
2. PCB Integration:
When integrating the TTGO T8 into a larger PCB, precise dimensions are necessary for accurate placement and routing of tracks and components. This is particularly important for avoiding signal interference or shorts.
3. 3D Printing Cases:
If you're using 3D printing to create a case, accurate dimensions are crucial for generating a successful model. The slightest error can result in a case that doesn't fit the board correctly.
4. Space Constraints:
In projects with limited space, accurately assessing the TTGO T8's footprint ensures proper integration and avoids design clashes.
Tips for Working with the TTGO T8:
- Always Double-Check Measurements: Before beginning any project, verify the dimensions of your specific TTGO T8 board. Minor variations can occur.
- Consider Component Height: Account for the height of additional components like sensors or displays when designing your project.
- Use CAD Software: For precise design work, utilize CAD software to ensure accurate placement and integration of the TTGO T8.
By carefully considering the LilyGO TTGO T8 ESP32-S2's dimensions, you can create successful and well-integrated projects. This guide provides the necessary information to accurately plan and execute your projects, ensuring compatibility and optimal performance. Remember that while the dimensions provided here are highly accurate, it’s always recommended to double-check with your specific device.
