Assembly of the payload module
The spacecraft contains in its composition the target equipment that ensures the fulfillment of its main mission. This equipment, for which the spacecraft is being created, is called a payload.
The basic structure of the OrbiCraft 3D designer has one payload - a camera as part of the UHF+HF+ERS module. To create your own payloads, you can use the Arduino hardware and software platform included with the payload unit.
The information exchange between the Arduino microcontroller and the on-board computer takes place using an expansion board (the so-called Shield), which is installed on a board with a microcontroller. The expansion board contains a connector for connecting to the cable network via a standard designer cable. Six sensors can be connected to the Troyka Slot Shield board, which are used for various Arduino-based projects.
Components required for assembly (Picture 1):
- all parts labeled payload (two bases, two walls, two transparent panels);
- additional parts (guides – 4 pcs., cover – 1 pc., stop – 1 pc., bracket for arduino MEGA2650 board – 1 pc., bracket for Troyka Slot Shield board – 1 pc.);
- boards (payload board – 1 pc., arduino MEGA2650 board – 1 pc., Troyka Slot Shield board – 1 pc.);
- fasteners (screws with a cylindrical head M2x6 – 9 pcs., M3x12 – 6 pcs., M3x8 – 2 pcs.).

Assembly order
1) Install L-shaped guides on the lower base (marked: payload ↓) (Picture 2):

11) Install the top cover on the assembled housing. To do this, combine the cutouts on the top cover and the protrusions of the two walls, the transparent panel and the bracket, and snap it with effort (Picture 12):

12) Install a second transparent panel. To do this, run it along the horizontal guides in the bases. (If additional payload shields are used, do not install) (Picture 13):
