Electronics and assembly
Sensorable camera is a low power edge computer for smart applications with limited power and bandwidth. It is based on Samsung G935F smartphone board with auxiliary chassis and electronics.
Applications:
- outdoor security
- remote site monitoring
- beach / nature cams
- traffic monitoring
- vehicle counting
- ALPR / ANPR
- speed control and monitoring
Main components
- G935F board with a rear camera and antennas
- custom G935f chassis
- Hammonds IP65 enclosure
- auxiliary PSU
- power and USB connectors
The camera can be assembled, programmed, tested and deployed by a sufficiently skilled technician.
See BOM-combined.csv for the full list of parts.
Packaging options
- Chassis only for OEM embedding: 155mm x 75mm x 15mm
- Unsealed enclosure for OEM embedding: 165mm x 86mm x 20mm
- Sealed enclosure for external use: 165mm x 86mm x 56mm
The sealed enclosure may include an optional battery pack. See https://github.com/sensorable/batt-pack for more info.
Auxiliary components
The chassis has mounting options for a few auxiliary components. They can also be connected externally via USB or RS232.
- Built-in Houston-Radar SS400
- Built-in generic OEM radar
- USB/RS232 adapter
- External Houston-Radar
- External AGD radar
Ordering and assembly
This is only a high level overview to give you an idea what's involved. We recommend getting in touch with us to help you with your production run.
Check the combined BOM for the full list of components and recommended suppkiers. We tried to minimise the number of suppliers and use only the reputable ones:
- Elelctronic parts: DigiKey
- Fastenings: Accu
- PCB: JlcPCB
- PCBA: JlcPCB or your local PCBA specialist
The final assembly is expected to be done in-house or by a trusted local embedded systems specialist as it involves testing, loading the software and configuring the devices.
See other repositories for the mechanical (chassis) and software (ROM, tools, apps, etc).

Questions
How big is the G935f psu PCB?
It measures 37 × 49.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the G935f psu use?
52 parts, built around the TPS54339DDA. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the G935f psu KiCad files?
From the sensorable/g935-electronics repository on GitHub, at the commit this page was made from: the board is psu/g935f-psu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the G935f psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask sensorable before reusing the design.
