The LoRa+GPS Cap for Cardputer Adv is a high‑performance expansion module that combines SX1262 LoRa communication and ATGM336H GNSS positioning in a single compact cap. Designed for the M5Stack Cardputer Adv Version , it delivers 868–923 MHz long‑range, low‑power wireless links and multi‑system satellite positioning with high accuracy. With an external SMA LoRa antenna for stronger anti‑interference and a built‑in ceramic GPS antenna , it ensures reliable connectivity and precise location tracking — even in weak signal environments.
