Summary

This enclosure is designed for the TTGO T-Display ESP32 boards with a 1.14" LCD screen. It ensures that the USB-C cable can be yank out without pulling out the board, press the buttons without fear of breakage. Includes space for an 803540/403540 LiPo battery with a handy on/off switch to prevent unwanted drain. Print without supports and skip the need for screws.

These cases fit:

• TTGO T-Display ESP32 boards with a 1.14" LCD screen
• 803540/403540 LiPo batteries (accommodates ~10mm extra length without switch)
• SS12D00G3 switch to prevent battery drain when not in use

Also there's a hole on the diagonal face to see the charge indicator LED, sized to fit a 1.75mm transparent filament for light guidance.

Heads Up About Screens!

Recent TTGO T-Display versions might have a slightly different screen with a blue tint and a longer cable. This can affect the fit in some cases.

Use the provided "TestFit" models to find the perfect fit for your screen position. Start with "Offset0" for black chin screens and "Offset3" for blue chin screens.
