T-Mini E-Paper S3 Meshtastic Node with Tiny Display
Flash Meshtastic firmware onto the LILYGO T-Mini E-Paper S3 for a compact off-grid LoRa mesh node with a 1.02" e-paper status display showing node info and received messages.
Overview
The LILYGO T-Mini E-Paper S3 is one of the world's smallest ESP32-S3 e-paper development boards, featuring a 1.02-inch e-paper display (128×80) and full ESP32-S3 connectivity (WiFi + BLE 5.0). The official LilyGO-Mini-E-paper-S3 repository includes a dedicated Meshtastic folder with firmware and configuration for running the Meshtastic mesh networking stack on this tiny board.
The 1.02-inch e-paper display provides persistent node status, received messages, and mesh info without drawing any power when the content is static — ideal for a low-profile belt clip or pocket-sized mesh communicator.
