The LILYGO T-Echo Plus is another off-grid LoRa communicator, similar to Blackout Comms, ThinkNode M2, and Wio Tracker L1 Pro, but it features a metal attachment loop (designed like a climbing hook) for use in hiking, cycling, and off-grid environments. Built around a Nordic Semi nRF52840 MCU, it supports Bluetooth 5, Thread, Zigbee, and 802.15.4. It also adds an SX1262 LoRa transceiver, a 1.54-inch 200×200 SPI E-Paper display, and an L76K GNSS module. Other features include a 6-axis IMU (BHI260AP), a vibration motor, a buzzer, and a larger 2400mAh battery, along with a 1/4-inch mount and a “climbing finger loop” for gear attachment. Additional features include an optional BME280 sensor, Grove expansion, all in a rugged and compact enclosure with a long external antenna for extended LoRa range.
