Core2021-XF

Core2021-HF (Standard version)

This product uses the Semtech LR2021 long‑range ultra‑low‑power multi‑band LoRa® transceiver, supporting Sub‑GHz (150–960 MHz), the 2.4 GHz ISM band, and the 1.5–2.5 GHz licensed band, meeting the requirements of both terrestrial wireless communication and satellite communication applications. It is compatible with multiple modulation methods such as LoRa®, LoRaWAN®, (G)FSK, FLRC, and LR‑FHSS, making it suitable for LPWAN, smart home, industrial IoT, asset tracking, and satellite IoT scenarios. The LR2021 adopts the fourth‑generation LoRa® IP architecture, offering higher receive sensitivity, lower power consumption, and more flexible multi‑region single‑SKU design capabilities.
