M5Stack Cardputer-ADV & CAP LoRa-1262 Meshtastic Kit is a bundled portable Meshtastic solution built from two official M5Stack hardware components: the Cardputer ADV handheld terminal and the CAP LoRa-1262 expansion module. This listing is intentionally created as a combined kit, not as a single standalone component, and is prepared with Meshtastic firmware preflashed for faster deployment. The bundle joins a keyboard-equipped ESP32-S3 handheld platform with a dedicated SX1262 LoRa and GNSS expansion board. Together, the two parts form a compact portable node suitable for off-grid text messaging, mesh communication, and location-aware field use. What This Kit Combines Cardputer ADV base device: Provides the handheld computer body, display, keyboard, battery, audio, storage support, and ESP32-S3 processing platform. CAP LoRa-1262 module: Adds LoRa wireless communication, antenna connection, and GNSS positioning capability to the handheld platform. Ready-to-deploy pairing: Brings both official parts together as the practical M5Stack Meshtastic hardware combination. Combined Features Portable Meshtastic platform: Built for handheld LoRa messaging and mobile mesh networking. ESP32-S3 core system: Uses the Cardputer ADV as the main controller and interface device. Integrated user interface: 1.14-inch display, 56-key keyboard, battery power, speaker, microphone, and 3.5mm audio support are part of the base unit. LoRa communication expansion: The CAP module adds the SX1262 transceiver with strong long-range wireless capability. GNSS-ready operation: The CAP module adds ATGM336H/AT6668 positioning support for field and mapping scenarios. Preflashed convenience: Firmware is prepared for quicker Meshtastic setup and deployment.
