Description

This STEVAL-STKNX1CB is a designed board with the STKNX as 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 both 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.

An open SDK with third-party KNX stack and an ETS database are available for this board, the SDK, and ETS DD can be used by customers for study and estimation.

An SWD interface and a UART interface on the board for programming and debugging.

The standard KNX programming button and LED are present on the kit. In addition, four basic buttons and four LEDs are available to emulate basic KNX sensors/actuators or to propose any debug facility.

The evaluation kit provides isolators between the microcontroller and the STKNX.

Disabled by default, they can be enabled to allow development in any condition of an SELV product.

An auxiliary power supply can used on the board.

Important:

These evaluation boards are custom designed and built, in small quantities, according to specific requests from customers and are destined for evaluation and testing of ST products in a research and development setting. Please contact ST to provide your specific requests and get your custom built board(s).
