LilyGo T-Deck - Setup Guide

The T-Deck is a standalone LoRa communicator with a 2.8" touchscreen, physical QWERTY keyboard, trackball, speaker, and microphone - enabling full mesh network operation without a phone. Note that the base T-Deck does not include GPS; see the T-Deck Plus for GPS functionality.

Entering Bootloader / DFU Mode - UNIQUE METHOD

Primary Method (Trackball):

1. Flip the power switch to OFF.
2. Press and hold the trackball (physically depress it - it clicks).
3. While holding the trackball, flip the power switch to ON.
4. Continue holding the trackball for 2 - 3 seconds, then release.
5. Confirmation: A blank screen with the backlight off indicates successful DFU mode entry.

Alternative Method (Side Reset):

1. With the device powered on, press and hold the trackball.
2. While holding, press the side reset button briefly.
3. Release both. Blank screen with backlight off = DFU mode.

Firmware Flashing

2. Connect via USB-C to your computer.
3. Open Chrome or Edge and navigate to:
   • MeshCore: flasher.meshcore.io
   • Meshtastic: flasher.meshtastic.org
4. Select T-Deck from the device list.
5. Click Flash and grant serial port access.
6. Wait for completion. Device reboots automatically.

Known Quirks

• Bootloader entry using the trackball can be unintuitive at first - ensure you press the trackball before turning on power.
• Higher power draw than simpler boards; plan battery capacity accordingly.
• For GPS functionality, the T-Deck Plus is required.
