The LilyGO TTGO T8 ESP32-S2 is a popular and versatile development board based on the ESP32-S2 microcontroller. Understanding its dimensions is crucial for enclosure design, PCB integration, and overall project planning. This guide provides detailed information on the TTGO T8's physical characteristics, helping you make informed decisions for your next project.
Precise Dimensions of the LilyGO TTGO T8 ESP32-S2
While precise measurements can vary slightly due to manufacturing tolerances, the generally accepted dimensions of the LilyGO TTGO T8 ESP32-S2 are as follows:
- Length: Approximately 30mm
- Width: Approximately 25mm
- Thickness: Approximately 10mm (this includes the height of any components like the battery connector or antenna). The PCB itself is thinner.
These are approximate dimensions, and it's always best to refer to the official schematics or directly measure your specific board for highly accurate measurements. Slight variations may occur between different batches or revisions of the board.
Understanding the Importance of Accurate Dimensions
Knowing the precise dimensions is essential for several reasons:
- Enclosure Design: Accurate measurements are crucial for designing custom enclosures or 3D-printed cases. Incorrect dimensions can lead to a poorly fitting case, potentially damaging the board or hindering access to components.
- PCB Integration: If you plan to integrate the TTGO T8 into a larger PCB design, knowing its dimensions ensures proper spacing and avoids component clashes.
- Project Planning: Accurate dimensions inform the overall size and footprint of your project, impacting factors like weight, power consumption, and placement within a larger system.
Beyond the Basic Dimensions: Key Considerations
While length, width, and thickness are the primary dimensions, consider these additional factors:
- Component Height: The presence of components like the battery connector, antenna, and headers can influence the overall height and footprint of the board. Measure these carefully for precise placement in your project.
- Mounting Holes: If your project requires mounting the TTGO T8, the location and size of any mounting holes must be taken into consideration.
- Connector Locations: The positions of connectors like USB, GPIO pins, and the battery connector are crucial for proper wiring and connection. Consult the TTGO T8 schematic for the precise location of each connector.
Where to Find Detailed Specifications
For the most precise and up-to-date dimensions and specifications, always refer to the official LilyGO documentation or the schematic provided for your specific revision of the TTGO T8 ESP32-S2. This ensures accuracy and compatibility.
Conclusion: Accurate Dimensions are Key
The LilyGO TTGO T8 ESP32-S2 is a versatile board, but successful project implementation relies heavily on understanding its physical characteristics. By carefully considering its dimensions and referring to the official documentation, you can ensure a smooth and successful development process. Remember to always double-check your measurements before committing to design choices or purchasing enclosures.
