M5Stack Cardputer Mesh Kit

The Cardputer Mesh Kit bundles M5Stack's keyboard-equipped ESP32ESP32A chipset of microcontroller made/designed by Espressif, used by a number of devices. Higher power usage than nRF52, but often cheaper and supports Wi-Fi if desired.-S3 Cardputer ADV with a snap-on LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures. + GNSSGNSS (Global Navigation Satellite System). A multi-constellation satellite positioning receiver. Hardware listing GNSS support typically receives GPS, BeiDou, GLONASS and QZSS. cap ("Cap LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures.-1262"), preloaded with Meshtastic — a self-contained pocket mesh messaging terminal.

Specifications
