MESH-S
DIY reference for outdoor mesh experiments
Solar power example
Example setup for solar energy harvesting in DIY contexts.
Winter experiment notes
Telemetry samples from low-light conditions.
ASA enclosure concept
Printed housing example for outdoor use; results may vary.
Modular DIY platform
Field-friendly layout with replaceable core modules; self-assembly required.
Telemetry snapshot
Example Home Assistant telemetry from DIY experiments.
Winter behavior observations
Illustrative internal layout
Reference configuration in 6 views
Power core layout
Reference placement of the MPPT controller and main node board on the spacer plate; layout can be adapted.
Battery pack positioning
Example location for the 4×18650 battery pack with cable routing shown for reference.
RF path routing
Illustrative routing of the RF path (U.FL → N-Type) prior to closing the enclosure.
Sealing concept
Reference gasket placement and enclosure closure for weather exposure considerations.
System check (reference)
Example checklist items for power checks, node startup, and LoRa mesh connectivity.
Outdoor mounting context
Reference deployment context for DIY builds; assembly, wiring, and commissioning are completed by the builder.
Moisture considerations
Sealed layout concept
No external interfaces
The enclosure example uses no external service ports or connectors. Access to electronics is only possible by opening the housing, reducing potential ingress points for moisture.
Silicone gasket
Full perimeter sealing
A continuous silicone gasket can help seal the enclosure halves, aiming to reduce exposure to rain, splashes, and humidity.
Pressure equalization vent
Membrane-based breathing
A pressure equalization membrane is intended to balance internal pressure changes caused by temperature fluctuations while aiming to limit moisture ingress.
Silica gel compartment
Passive humidity control
An internal silica gel compartment can capture residual moisture, helping limit condensation in DIY outdoor experiments.
Mounting options for DIY builds
Universal mounting system
Modular attachment interface
The mounting lid is presented as a universal attachment concept, showing how a DIY build could be installed on a range of structures without adapters or enclosure modifications.
Round structures
10 mm – 60 mm diameter
Example compatibility with vertical and horizontal poles with diameters from 10 mm to 60 mm. Two mounting hole offsets show possible positioning, enabling the use of cable ties or metal clamps.
Rectangular profiles
10×10 mm – 60×60 mm
An integrated profile geometry illustrates mounting on rectangular structures such as aluminum profiles and frames from 10×10 mm up to 60×60 mm.
Quick-release bracket
Optional accessory
A dedicated quick-release bracket example shows a mechanical latch system. Two release levers disengage four locking pins, enabling fast removal without tools or enclosure disassembly.
Magnetic mounting option
Optional configuration
The bracket can be paired with optional high-strength magnets (up to Ø56 mm) for temporary installation on metal structures while keeping the node removable.
