Mesh Node T1 is a lightweight, rugged card‑sized LoRa terminal, built around the nRF52840 and SX1262, it supports both BLE (short‑range high‑speed) and LoRa (long‑range low‑power wide‑area coverage). Integrated multi‑constellation GNSS, a 9‑axis IMU, a buzzer, and a 0.96‑inch TFT colour display provide comprehensive situational awareness including location, heading, and motion alerts. With an 11 µA sleep current and an 1850 mAh battery, it ensures extended outdoor operation, while its IP67 rating protects against rain, dust, and humidity. The native firmware supports peer search and map track drawing, and is compatible with open‑source projects such as Meshtastic and MeshCore. It also allows custom Arduino‑based development for implementing private protocols.
