LilyGo TTGO T3 ESP32-S3 V1.3 868MHz with 0.96 inch display

The LILYGO T3 S3 V1.3 is a versatile LoRa development board based on the ESP32-S3 microcontroller with an integrated 0.96-inch OLED display and SX1262 LoRa transceiver for the 868 MHz frequency. The board combines the computing power of the ESP32-S3FH4R2 dual-core processor with 4 MB Flash and 2 MB PSRAM with reliable long-range radio communication for European LoRa networks. The monochrome OLED display with 128 × 64 pixels allows the display of status data and debug information directly on the device. The board supports both USB power supply and 3.7 V LiPo batteries with integrated charging circuit and battery switch for mobile use.
