Lilygo T-Echo Lite Kit

LILYGO T-Echo Lite

The LILYGO T-Echo Lite is a compact, ultra-low-power LoRa development board based on the Nordic nRF52840. It features a 1.22-inch e-Paper display, SX1262 LoRa transceiver, 9-axis IMU, and excellent power efficiency. Ideal for portable Meshtastic nodes, low-power IoT projects, and off-grid communication where size and battery life are critical.

NOTES

• This is the compact “Lite” version of the T-Echo series — significantly smaller and more power-efficient than the standard T-Echo / T-Echo Plus
• Does not include the KeyShield / keyboard expansion
• Excellent for long-runtime Meshtastic nodes and low-power applications
• Deep sleep performance makes it one of the most power-efficient LILYGO LoRa boards available
