Arduino-compatible shields available from RS Components help to accelerate KNX-compliant implementations

RS Components (RS), a trading brand of Electrocomponents plc (LSE: ECM), a global omni-channel solutions partner for industrial customers and suppliers, now stocks NCN5100ASGEVB evaluation boards from ON Semiconductor®. These Arduino-compatible units are designed to facilitate prototyping work, comprising all the constituent components necessary to create smart home and building automation systems based on KNX communication technology. Suitable for use with a wide variety of leading microcontrollers, they can be plugged directly into existing development platforms – enabling projects to be completed in the shortest possible timeframe.

There are three different variants of the NCN5100ASGEVB from ON Semiconductor, which utilise the company’s NCN5110, NCN5121 and NCN5130 KNX certified transceiver ICs respectively. This means that both standard or more sophisticated implementations can be addressed. Each of these transceivers has a pair of high-efficiency DC/DC converters integrated. Focused predominantly on supplying the transceiver and the system MCU, the first DC/DC converter provides a fixed 3.3V output. In contrast, the output for the second converter is adjustable across a wide range of voltages, covering 1.2V to 21V.

This can be employed for powering peripheral parts such as a relay, display or other analogue IOs. Thanks to the industry-leading power delivery capabilities of these transceivers, plus the elevated levels of operational efficiency, with ultra-low bus voltage drop and quiescent current, engineers will be able to explore potential opportunities for KNX in much more power-hungry application scenarios.

For the boards featuring the streamlined NCN5110 analogue front-end, all the timings need to be dealt with by the host microcontroller, while the NCN5121 and NCN5130 versions have extra functionality added. In addition to the PHY, a MAC layer has been incorporated into both of these transceivers, thereby reducing the software development work involved. Additionally, the high degree of component integration these boards exhibit means that size and bill-of-materials costs are kept to an absolute minimum.

The ON Semiconductor NCN5100ASGEVB evaluation boards are shipping now from RS in the Asia Pacific, EMEA and North America regions.
