Ultra compact MeshCore / Meshtastic Companion
Print Profile(1)
Description
This project was created with the aim of developing the most compact and practical everyday case possible for a mobile MeshCore/Meshtastic node.
The combination of Seeed Studio XIAO nRF52840 and Wio-SX1262 enables a powerful LoRa mesh node with minimal dimensions and low power consumption.
The complete system is housed in a cylindrical, screw-together case measuring only 26 × 100 mm and has a total weight of only about 40 g. This allows the device to be carried easily and discreetly in a pocket, backpack or EDC setup.
