NomadShell is a rugged, parametric enclosure designed specifically for Meshtastic deployments in harsh environments. It provides a secure, weather-resistant housing for RAKwireless WisBlock components and is ideal for off-grid, portable communication nodes.
Battery connect-disconnect
NomadShell is engineered to fit the following modules:
The system is powered by three 18650 Li-ion batteries in parallel, providing long-lasting operation in the field.
The batteries are housed in a dedicated battery compartment for easy maintenance and swapping.
NomadShell is composed of two main parts:
- Main electronics housing (RAK modules)
- Battery compartment (3x18650 cell pack)
These components are joined using a 3-pin magnetic pogo connector, enabling reliable electrical contact and quick assembly/disassembly.
An O-ring seal around the interface ensures additional water resistance, making the enclosure suitable for outdoor use in challenging conditions.
Designed with field deployment in mind, NomadShell includes:
- Water-resistant seals
- Durable materials
- Magnetic modularity
Perfect for hikers, adventurers, remote IoT setups, and emergency mesh communication networks.
- Off-grid Meshtastic communication nodes
- Field-deployable GPS+LoRa devices
- Environmental monitoring
- Emergency mesh setups
The design was performed with FreeCAD_weekly-builds-40006. All the variables are location on the VarSet.
The pcb stand-offs can be changed from the sketch: main_body-> main_body001->pcb_standoff001, so you can change the type of the module used. The USB-C opening can be changed on the sketch: main_body-> main_body001->usb_cap
Between the base and the cover is a gasket, printed with TPU(PrimaSelect TPU 64D). All the other parts are printed with PLA. A small portion of black hot glue or 2 part epoxy is needed to placed behind the pogo pins to stop water from getting inside the battery and main case.
The usb_cover_base needs to be glued on the the main body.
The central pin of the magnetic pogo pin will be connected to GND and the 2 outer ones on the 3.3V. The battery can be connected on frond and backwards.
Use the instalation_tool_pogopins to install the magnetic pogo pins.
A small drop of glue is needed to be placed on the o-ring used between the main and battery part. The orion is better to be glued on battery part.
