Modification of Existing MJVision Camera Enclosure for Jetson Orin NX and FRAMOS Cameras Anyone

# Modification of Existing MJVision Camera Enclosure for Jetson Orin NX and FRAMOS Cameras

## Project overview

An enclosure has already been fully designed for the **MJVision panoramic football camera** using the **Radxa ROCK 5B+** motherboard. The existing project includes the enclosure CAD/source files, STEP assemblies, STL files, drawings, internal component holders, battery holder, tripod mount, buttons, connector openings, ventilation and assembly documentation.

This new project is **not a completely new enclosure design**. The objective is to modify and improve the existing enclosure so that it can accommodate the new Jetson and FRAMOS hardware while reusing as much of the accepted design as possible.

The new enclosure must be weather-resistant for outdoor football recording, with an **IP65 design target** against rain, dust and splashes. It is not intended for underwater use.

## Main new components

### Yahboom Jetson Orin NX Super 16 GB

- Approximate assembly dimensions without plastic base: **100 × 80.80 × 34.84 mm**
- Recommended minimum reserved volume: **110 × 92 × 45 mm**
- Includes heatsink, fan and NVMe SSD
- Adequate fan airflow and heat exhaust must be maintained
- Power, USB, Ethernet, DisplayPort, camera and NVMe access must remain available
- A removable internal tray should be used
- Final mounting-hole positions must be verified against the physical board

### Two FRAMOS IMX678 cameras

Exact model:

**FSM:GO-IMX678C-M12-L110A-PM-A1Q1**

Dimensions for each camera:

- PCB: **26.5 × 26.5 mm**
- Mounting-hole pattern: **22 × 22 mm**
- Four mounting holes: **Ø2.2 mm**
- Approximate lens diameter: **20 mm**
- Approximate camera assembly depth: **32.6 mm**
- Recommended reserved volume: **35 × 35 × 45 mm per camera**

The two camera holders must be rigid and non-adjustable.

Camera geometry:

- Horizontal FOV per camera: **110°**
- Fixed angle between optical axes: **62°**
- Each camera positioned 31° outward from the enclosure centreline
- Theoretical panoramic coverage: approximately **172°**
- Theoretical overlap: approximately **48°**

The lens windows and sealing components must not obstruct the full horizontal, vertical or diagonal FOV. The camera windows must be gasketed and suitable for outdoor use.

### 5G modem and USB adapter

The modem is:

**SIMCom SIM8262E-M2**

- Modem dimensions: **42 × 30 × 2.3 mm**
- M.2 3042 format
- Four antenna connections

The modem will be installed on the KALEA M.2 B-Key to USB 3.0 adapter:

https://www.amazon.fr/dp/B0933MYR3K

The adapter does not have a reliable published mechanical drawing. Reserve:

- Minimum adapter assembly space: **90 × 50 × 20 mm**
- Preferred complete installation area: **120 × 60 × 25 mm**, including the USB connector, cable bends and antenna connections

The adapter should use an adjustable or removable cradle rather than assumed mounting-hole positions.

External SIM access must be positioned close to the adapter’s SIM slot so that the SIM extension route remains short. The SIM opening must use a sealed removable cover.

## Antennas

The enclosure must provide space and cable routing for:

- **Two Wi-Fi antennas**
- **Four 5G antennas**
- Six antenna cable routes in total

For internal Wi-Fi antennas, reserve approximately:

- **100 × 20 × 5 mm per antenna**
- At least 50 mm separation where practical
- Clearance from the Jetson heatsink, battery, metal fasteners and 5G antennas

If external Wi-Fi antennas are used, they must use sealed IP-rated bulkhead connectors.

The four 5G antenna cables must include retention clips, service loops and safe bend radii.

## Existing features to retain where practical

The following elements from the completed ROCK 5B+ enclosure should be reused or adapted:

- Outer enclosure shape and general dimensions
- ENERpower 4S2P battery holder
- Reinforced **1/4"-20 UNC metal tripod insert**
- Power and Bluetooth buttons
- Status LED
- External charging connection
- Internal power electronics
- Cable-retention features
- Accessible maintenance and assembly arrangement

If the same outer shell cannot practically support the new hardware, the designer should modify only the minimum necessary parts, such as:

- Internal motherboard tray
- Camera holders
- Connector panel
- SIM-access panel
- Sealing and ventilation components

## Required deliverables

The project must include:

- Modified native CAD/source files
- Complete STEP assembly with all component envelopes
- Printable STL files
- Internal and exploded assembly drawings
- Fully dimensioned manufacturing drawings
- Component and fastener BOM
- Cable-routing drawings
- Gasket and sealing specifications
- Camera FOV-clearance verification
- Internal interference and clearance verification
- Assembly and maintenance instructions
- Final design consistency between CAD, STEP and STL files

The existing enclosure CAD package will be provided as the starting point. read less
