M5Stack Cardputer Mesh Kit
M5Stack Cardputer Mesh Kit is a portable communication terminal kit that combines the Cardputer-Adv controller with the Cap LoRa-1262 communication expansion module. The kit supports LoRa Mesh networking and GNSS-based positioning in a compact, card-sized form factor for field communication, location-aware nodes, and portable device development. The Cardputer mesh kit centers on the Stamp-S3A-based Cardputer-Adv, which provides a display, compact keyboard, audio functions, motion sensing, infrared output, microSD storage, Grove connectivity, and an EXT expansion bus. The Cap LoRa-1262 module connects via the EXT 2.54-14P interface and adds SX1262-based LoRa communication, an RP-SMA antenna interface, and AT6668 GNSS positioning with support for multiple satellite systems. M5Stack Cardputer Mesh Kit supports outdoor communication, node deployment, location tracking, in-vehicle positioning and navigation, and embedded systems learning.
