Arduino-compatible shields accelerate KNX-compliant implementations

29-12-2020 | RS Components | Subs & Systems

RS Components is now stocking NCN5100ASGEVB evaluation boards from ON Semiconductor. These Arduino-compatible units are created to enable prototyping work, incorporating all the constituent components required to produce smart home and building automation systems based on KNX communication technology. Suited for use with a wide assortment of leading microcontrollers, they can be plugged directly into current development platforms - allowing projects to be finished in the shortest possible timeframe.


There are three different variants of the board which use the company’s NCN5110, NCN5121 and NCN5130 KNX certified transceiver ICs respectively. This indicates that both standard or more sophisticated implementations can be managed. Each of these transceivers offers a pair of high-efficiency DC-DC converters integrated. Concentrated predominantly on providing the transceiver and the system MCU, the first DC-DC converter offers a fixed 3.3V output. In contrast, the output for the second converter is adaptable across a broad range of voltages, covering 1.2V to 21V.


For the boards offering the streamlined NCN5110 analogue front-end, all the timings require to be dealt with by the host microcontroller, while the NCN5121 and NCN5130 versions provide extra functionality added. As well as the PHY, a MAC layer has been integrated into both of these transceivers, thereby decreasing the software development work concerned. Further, the high degree of component integration these boards display means that size and BoM costs are kept to an absolute minimum.
