ByteSnap offers design expertise for all stages of product development, from Technical Specification to Long Term Support. With a fully integrated hardware and software team, we are the one-stop solution for any project.

We specialise in Intrinsically Safe Design

There are many ways to make equipment safe for use in hazardous environments, including encapsulation and explosion/flame proof enclosures. However, another key method is through intrinsic design. This can reduce material costs and increase flexibility in dimensions.

There are many situations where intrinsic safety is the optimal approach, including handheld devices and industrial sensors. We have extensive experience in Low Power Design, including wireless products.


The ATEX Product Design process differs considerably from other electronic devices due to the extra considerations, for example the Industrial Design (ID) steps shown on the diagram are essential to ensure an appropriate Ingress Protection (IP) rating is achieved so explosive particles cannot enter the device.

ByteSnap is experienced in reducing power across the device without compromising functionality, and has been through the regular reviews and checks with the certification authority, and this experience and knowledge reduces time-to-market.

What categories of products require ATEX conscious design?

ATEX is an acronym for ATmospheres EXplosible and refers to any hazardous environment containing gases or dust particles that carry an explosion or fire risk – for example, petrochemical plants or flour mills. Due to the higher risk to workers and equipment, all electronic devices in these areas must have ATEX Certification. The Certification required depends on the level of danger, classified as Zones in Europe and by the IEC and as Classes in the USA.

Current classifications are as follows:


Definition of Zone or Division

Zone 0 (EU and IEC) (Gas / Vapour / Mist)

Class I Division 1 (USA) (Gases)

Category 1G

An explosive atmosphere consisting of a mixture with air of dangerous substances is present continuously or for long periods

Zone 1 (Gas / Vapour / Mist)

Class I Division 1 (Gases)

Category 2G

An explosive atmosphere is likely to occur in normal operation occasionally

Zone 2 (Gas / Vapour / Mist)

Class I Division 2 (Gases)

Category 3G

An explosive atmosphere is unlikely to occur, and if it does, is only present for a short period

Zone 20 (EU and IEC) (Dusts)

Class II Division 1 (USA) (Dusts)

Category 1D

An explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods

Zone 21 (Dusts)

Class II Division 1 (Dusts)

Category 2D

An explosive atmosphere is likely to occasionally occur in normal operation

Zone 22 (Dusts)

Class II Division 2 (Dusts)

Category 3D

An explosive atmosphere is unlikely to occur, and if it does, is only present for a short period

ATEX specifically refers to two EU directives, concerning the protection of workers and equipment in potentially hazardous environments.

What about Brexit?

These directives were written into UK legislation in 2002 as part of the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR). As such, Brexit is not going to affect ATEX design regulations, however, as ATEX certified products require CE Marking, this will change in the UK on 1 January 2021. For more information, read our guide to UKCA and CE Marking.In order to ensure the safety of products in use in hazardous environments, manufacturers and suppliers must have their products tested for conformity and certified. ByteSnap has experience in supporting customers in this – and can save you time and money on your product development.

See how we helped Geotechnical Instruments Ltd develop their intrinsically safe biogas analyser:

“Great Credentials, Proven Track Record”

“They had great credentials and a proven track record in both hardware and firmware development for Windows CE applications, along with some experience of intrinsically safe design. Very quickly, ByteSnap designed and implemented both the hardware and O/S for the new platform. I’d happily recommend ByteSnap for this type of work, and would work with them again.”
Steve Earp – Project Manager, Geotechnical Instruments Ltd


We offer experience and reliable support throughout the product and PCB or electronic board design life cycle, with both software and hardware engineers working side-by-side on projects to identify the best solution for each client.

We’re Not Just Software Engineers

With an integrated hardware and software team, we are experts in embedded electronics. We also have the know how to communicate with all design engineers including mechanical and system suppliers.

Complete Solution, Team Integration

We are flexible in our approach. If you have your own team, we can support your existing employees. Or if you need end-to-end design, we can cover all stages of the embedded system design process.

We Focus a Solution to Your Problem

From using off the shelf electronics to fully bespoke designs, we choose the best course of development for you. Most importantly, we are not tied to franchises and offer the full freedom of today’s technology.

Experience the Security of Consistency

You will be assigned your own experienced project manager and engineer. They will then stay with you throughout the full embedded Linux design process.

Own Your End Product IP

Having ownership of your IP gives your business the competitive edge and flexibility for future modifications. This also reduces your risk for copycat products.

Broad Array of Project Experience

We do not focus on a single market vertical. Due to our broad array of project experience, we are certain that we have experience in your industry sector.


For over 10 years, clients have engaged ByteSnap Design to deliver exceptional embedded Linux development projects. We are trusted by companies across the UK and beyond, providing them with business and deep technical expertise under one roof.
