M5Stack LoRa + GPS Cap for Cardputer Adv [Discontinued]

This is a high-performance LoRa communication and GNSS global navigation expansion module designed for the M5Stack Cardputer Adv.

The LoRa module is based on the SX1262 chip, equipped by default with an external SMA antenna, providing stronger anti-interference capability and long-distance communication performance. It supports the 868MHz ~ 923MHz frequency band and offers long-range, low-power wireless links for IoT applications.

The GPS module adopts the AT6668-based solution, with a built-in ceramic antenna for precise and reliable satellite positioning services. It supports multi-frequency, multi-mode GNSS signal reception, enabling the reception of signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS) and supports both multi-system joint positioning and standalone positioning with strong anti-interference capability and high positioning accuracy.
