M5Stack Cardputer goes off-grid with new Mesh Kit featuring LoRa, GNSS, and Meshtastic support

M5Stack has just launched the Cardputer Mesh Kit, a portable, card-sized Meshtastic communication terminal built around the ESP32-S3-powered Cardputer-Adv controller and a new LoRa expansion module (CapLoRa-1262). The kit is essentially a modular upgrade to the original Cardputer, where the base unit handles the UI via a 56-key keyboard and a 1.14-inch LCD. The added “Cap” module adds a Semtech SX1262 transceiver and an AT6668 GNSS module, allowing for off-grid text messaging and GPS location tracking without relying on cellular networks.
