What's in the build
Mesh Pocket 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 Pocket 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 Pocket Frame. See Frame & Connections for the connector standard, and the Compatibility Matrix for the combination rules.
Frame
The Pocket 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.
