Spotted! GCT USB1035 On The Newest Raspberry Pi 3 Model B+


It’s not quite the Raspberry Pi 4, but there is a new version available in the form of the Raspberry Pi 3 Model B+ which was launched on ‘Pi Day’ March 2018.

With enhanced processor speeds at 1.4GHz, upgraded wireless performance and new features such as Power-over-Ethernet support (with separate PoE HAT) to name a few, the latest version certainly is a good improvement from its predecessor, for a small premium.  Farnell, RS and Amazon are some of the great places where you can by your shiny new Raspberry Pi.

Dual USB, GCT, USB1035, Raspberry Pi 3 Model B+

For those who didn’t know, GCT have been supplying the dual USB connectors found on the device and reached a nice milestone with 10 million USB1035 connectors shipped back in May 2016.  This number continues to grow as we’ve still got our products on the latest variant, the GCT logo on the USB connector is clearly visible on all promotional photos!

This is testament to the trusty USB1035, GCT’s dual USB type A connector, a popular choice due to its product quality and reliability, short lead times and competitive pricing.  With more power and functionality being built into the Raspberry Pi, the versatility of the USB1035 as one of the primary I/O connections remains paramount.

We’re just happy to be a part of the latest and most powerful Raspberry Pi Model to date.  As we look forward to Raspberry Pi 4 and further iterations down the line, who knows what connectors might appear on these units… USB Type-C? Nano Sim Connectors?  PCB space is obviously at a premium so what would you like to see on them?

Whatever they might be, GCT have a comprehensive connector product line to support these innovations, see for yourself at

Nano SIM connector facilitates ultra-secure data access

Nano SIM connector facilitates ultra-secure data access

In today’s ever-more connected society, authenticating identities and protecting data is essential to keep users safe and enable services in personal devices, connected objects, the cloud and in between.

Two-factor authentication plays a key role in such protection strategies, and can be implemented as an easy to use solution using advanced smart card technology. Certificate-based technology generates and stores credentials such as private keys, passwords, and digital certificates inside the protected environment of the smart card chip.

In one such solution, users must supply both their personal authenticator device and password to authenticate, providing a critical second level of security beyond simple passwords alone to protect valuable digital business resources.

This innovatively-designed two-factor authenticator solution comes in the form of a USB stick. GCT is similarly innovative, being the first to market with a nano SIM connector – a product which is now in full production. This motivated a leading player in data security technology to partner with GCT for their first mutual project, to integrate GCT’s SIM8051 into the USB authenticator where the Nano SIM connector facilitates ultra-secure data access. The companies worked together to cost down the connector for production.

The connector allows use of a SIM to hold certificates for encryption purposes. The SIM’s architecture and ciphering provides better security than conventional chip memory, as well as being more cost-effective. This use of a SIM for memory capacity rather than wireless capability is almost unique.

While being an economical solution, the SIM8051 offers a durability of 1,500 cycles, with an operating temperature range of -40°C to +85°C. The housing material is LCP with UL94V-0 flame retardant rating.

Connector production is backed by extensive international support. Dealing directly with the customer in two different locations – Europe for design and Asia for production, GCT’s local presence in these markets was also instrumental to the smooth running of the project.

Taxis fare better with GCT custom cable assemblies

GCT Custom Cable Assemblies - Verifone Case StudyBlack cab drivers across London face many challenges, not only from stringent and changing legislation, but also from competitors such as Uber and Addison Lee. Traditional cabbies are fighting back though, with an action plan to guarantee a faster, smarter and greener future for London’s black cabs. Details include zero emission capable cabs by 2018, and adoption of new technologies such as fast Wi-Fi and electronic card payment with contactless support.

In fact, electronic payment ability has become mandatory since February 2016, when TfL announced that all licenced taxi drivers must offer passengers the option of paying their fare electronically at the point of sale.

Verifone has long been providing a valuable resource into this area; they are global market leaders in ePOS, offering over 25 years’ experience with taxi fleets. Their fully TfL compliant card payment solution accepts payment from all major Chip & PIN, swipe and contactless credit and debit cards, and can accept electronic payment via ApplePay and NFC enabled android devices.

The Challenge

Verifone’s provision of card payment technology to taxi fleets meant that they had to respond rapidly when TfL introduced their new legislation last year. They needed to fulfil an urgent request to equip nearly a quarter of London’s black cabs with not only ePOS card payment units, but also Fare Taximeters and taxi advertising systems that deliver a customer information channel on a 15” digital screen within the passenger compartment.

Their success in meeting the project’s tight deadlines was due in part to support from their trusted cable and connector supplier, GCT.  GCT designed a set of cable assemblies that, while being customised for connector arrangements and environmental resilience, were produced in the required production volumes within critical deadlines.

The GCT Custom Cable Assemblies Solution

GCT’s supply comprised four cable assembly types, using various custom combinations of Micro USB, USB, DSUB and Jack connectors. One example splits a USB A output into a Micro USB B male and a Micro USB B female connector; in another, the split is from mini HDMI to a DC Jack and DSUB 9 Pin connector.

The assemblies were customised for their environment as well as their connector combinations. The HDMI/DCJack/DSUB cable has a copper foil shield over its inner mould on the connectors to eliminate electrical noise interference and reduce signal attenuation. This also helps compliance with ATC and RoHS certifications. Additionally, the cables have a braid and PVC jacket to allow an extended flex cycle life – an important consideration as shock and vibration are ever-present parts of taxi vehicle operation.

As the cables were more complex than previously required, while being on a very tight delivery, GCT had to make special arrangements to meet Verifone’s requirements. After a prompt, early visit to Verifone’s premises to ensure a detailed understanding of the project, GCT set up a manufacturing plan that included extensive factory overtime. 100% quality checking and testing was performed, including extra technical and quality checks for the higher-complexity HDMI/DCJack/DSUB cable. Additionally, goods were delivered in batches to avoid any production line stop at Verifone.

“Success in this assignment depended in close co-operation between both companies,” comments Eren Ozkan, UK Project Manager at GCT, “Our task was made far easier, and turnaround was greatly facilitated, by the responsive support from Verifone’s engineers at all times throughout the project.”

The Feedback

Mike Wakefield, Inventory Manager at Verifone was also pleased with the project’s results. He comments:

“We originally approached GCT with this requirement because of our previous experience in working with them. Although these assemblies were more complex and on much shorter lead times than previous years’ deliveries, GCT’s production allowed us to meet our commitment to our customers. Although the project occasionally presented some technical challenges, we overcame these together in a timely manner.”
