Description
This STEVAL-4KNXDVCB is a designed board with STKNX as KNX device transceiver, low power STM32G070CB as main controller, ULN2803A as relay driver chip.
The STEVAL-4KNXDVCB runs with the KNX protocol.
With the use of STKNX, KNX signals can be transmitted between KNX BUS and MCU.
The microcontroller can be programmed by a dedicated SWD 5-pin connector.
The ULN2803A can provide an output voltage 50 V and current 500 mA.
This STEVAL-4KNXDVCB can use ETS software to set parameters to enable manual control and adjust action delay time of each channel.
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).
