Compact MeshCore / Meshtastic Companion
Print Profile(1)
Description
For this project, I finally wanted to give my unused Lilygo TTGO v1.0 / Heltec V2 / Heltec V3 boards a meaningful task – resulting in a compact case for a MeshCore Bluetooth Companion, optimized for mobile and everyday use
The power supply was particularly important to me: The case is deliberately designed so that it can be powered by a simple (free, 3D printed) battery adapter with either 3× AA batteries (LR6) or alternatively with a LiPo battery (e.g., 3000 mAh). The use of regular household batteries was absolutely intentional – AA cells are available practically everywhere, can be quickly replaced, and do not rely on special batteries or chargers. Ideal for outdoor use, emergency setups, or simply uncomplicated operation
The complete device, including batteries and flexible 868 MHz LoRa antenna, weighs only about 160 g with compact dimensions of 58 × 106 × 23 mm
