Lilygo

The LilyGo T-Echo Lite is the compact, energy-saving version of the T-Echo board, combining an nRF52840 microcontroller with a 868 MHz LoRa radio module and an E-Paper display in a robust, transparent housing. This board is ideal for energy-efficient sensor, tracking, and communication projects and is fully compatible with the Meshtastic firmware. The integrated nRF52840 controller supports Bluetooth 5, Thread, Zigbee, and 802.15.4. The power-saving E-Paper display permanently shows status information without consuming energy. The module can be powered via USB-C or a 3.7 V Li-Ion battery, with the voltage being measurable internally. Thanks to the integrated 868 MHz LoRa module, the board is perfect for long-range point-to-point or mesh communication in the European ISM band.
