Mesh Station Junior 1.0 datasheet — module set, form factor, dimensions, weight, firmware, and assembly.
Datasheet for Mesh Station Junior 1.0, the desktop Mesh Series build. For the user guide, see the Mesh Station Junior manual.
What's in the build
Mesh Station Junior is a complete assembly — three modules and the Frame that holds them. The modules join module-to-module, so there are no linking cables. Each module has its own datasheet:

Assembly
Mesh Station Junior is a three-layer module-to-module stack. The Core sits in front; the Power (battery) module mounts on the back of the Core; and the LoRa / GPS Expand stacks on the back of the Power module, which passes the connection through. No cables are used — each module joins to the next directly through its rear board-to-board (BTB) connector. The whole stack is held in a Station Frame with four screw-on legs. See Frame & Connections for the connector standard, and the Compatibility Matrix for the combination rules.
Frame
The Station Frame is built from these structural parts. The codes are Attaky's internal part codes — the full part names are maintained by the hardware structural group.

It also includes four brown screw-in legs (removable): they thread into the base to stand the device upright, and unscrew so you can pack it flat.
