LilyGo TTGO T-Mini ESP32- S3 EU868 with 1 inch E-Paper Display

The LILYGO T-Mini E-Paper S3 is an ultra-compact development board that combines an ESP32-S3 microcontroller with a 1.02-inch E-Paper display and LoRa radio technology. The ESP32-S3FN4R2 processor provides dual-core performance with 4 MB Flash and 2 MB PSRAM as well as integrated Wi-Fi and Bluetooth 5 LE. The E-Paper display retains the displayed content even without power and is excellently readable in direct sunlight. The integrated SX1262 LoRa transceiver operates on the European 868 MHz frequency and enables ranges of several kilometers for mesh networks and IoT communication.
