概要
The STDES-KNXKNOB is a smart knob used in KNX smart home and building.
This STDES-KNXKNOB is designed with STKNX as KNX device transceiver and low power STM32G071CB as main controller.
The STDES-KNXKNOB incorporates STISO621 between KNX transceiver and MCU, the L6981 as step-down converter with 30 V input and 12 V output, the ST1S40 as step-down switching regulator with 3 A DC and 5 V DC output, the LD39015 as 150 mA low quiescent current low noise voltage regulator.
The SMAJ40CA is used as a transient voltage suppressor (TVS).
The STDES-KNXKNOB reference design can communicate with LCD and BLDC motor.
By integrating with the KNX stack, this panel can control air conditioning, lighting, and RGB in a KNX home system.
With the aid of an LCD screen and RGB lights, the device offers visual feedback to enhance the user experience. Users can quickly operate the device by pressing four push buttons. Additionally, the device incorporates an encoder that enables more precise manipulation
