outcomes with minimal disruption. By doing so, businesses can reduce costs, improve productivity, and maximise the benefits of connected technologies. For instance, if a company had a 15-year-old CNC machine that features proprietary control software and an IoT incompatible control interface, a first reaction might be to replace the machine to keep up with the times – especially if said machine is incapable of being tampered with due to a service contract and causing common issues. However, what if rather than forking out the big bucks for a new machine, the old machine could be retrofitted in a non-invasive way that still allows for the reaping of the benefits of IoT? In this case, a CNC machine can be retrofitted with wireless connectivity to the Cloud utilising the previously explored wireless modules which allow the collection of machine data from the existing control system in the Cloud as well as remote control of the machine. Additionally, the aforementioned range of various sensors can be mounted and connected to improve the quality of range of data collected. This data can be visualised for improvements, understand the status of the machine, or used alongside artificial intelligence/machine learning (AI/ ML) applications to enable predicative maintenance and process optimisation. This approach allows older machines to get even more expected useful lifespan, aid in the digitisation process, reduce the need for outdated training, have a more positive environmental impact, and improved efficiencies. Owing to these factors on top of new machine spendings, businesses can expect a return of investment within the first couple of years via retrofitting. Würth Elektronik’s wide portfolio for retrofitting or new designs can be found on the DigiKey website.
stackable, adding functionality and room for prototyping. The boards cover a wide range of applications including sensors, Wi-Fi, wireless, and power. These boards are also expandable with other FeatherWings from Würth Elektronik or Feather/QWIIC form factor devices. For instance, Würth Elektronik's Sensor FeatherWing can be utilised across its temperature, humidity, acceleration, and absolute pressure sensors, connected over a shared I2C bus. If power application is the focus, then Würth Elektronik's MagI³C power FeatherWing is a good solution. This board features operating input voltages of 9, 12, 15, 18, and 24V, industrial rails and a maximum 36V input voltage with an additional USB connector for 5V input voltage to select by switch. Enhancing efficiency Efficiency lies at the core of successful IoT implementation, whether that be with a newer system or unlocking the potential of legacy ones. Here, retrofitting is key and Würth Elektronik provides the tools required to retrofit older systems and optimise workflows to achieve the best
