STEVAL-STKNX1CB

STEVAL-STKNX1CB is a second-generation miniature transceiver STKNX evaluation and development kit. It is a designed board with the STKNX as a KNX device transceiver, the low power STM32G070CBT6 as main controller, the STISO620/STISO621 as isolated devices and the L6983N33 as power supply device. Integrated VL53L3CX for KNX sensor development. All the necessary components are required to evaluate the performance of the STKNX circuit and to develop a KNX device on a twisted pair medium according to the TP1-256 standard. The evaluation kit provides isolators between the microcontroller and the STKNX. Applications include home automation, residential climate control and HVAC, lighting controls, large appliances, gas, and water metering.
