DALI Click Board™

Product Code: MIKROE-1297

The DALI Click Board™ from MikroE is an accessory board intended to provide Digital Addressable Lighting Interface (DALI) to your design. This board enables the user to control your home/office lighting. DALI Click Board™ is equipped with two optocouplers, push button and screw terminals. For communication with the target board microcontroller, the board uses four mikroBUS lines (RST, CS, PWM and INT). DALI Click Board™ supports the use of either 3.3V or 5V power supply, selectable by an SMD jumper. A green LED indicates the presence of power supply. A yellow LED indicates RX activity. DALI, a data protocol and transport mechanism, works as a true standard for professional digital lighting and lighting control. It allows easy integration of equipment from different vendors by offering a common platform while reducing installation costs. DALI Click Board™ requires 2 wires to devices for data transfer between MCU and devices by means of asynchronous, half-duplex, serial protocol. There can be up to 64 DALI devices on a single DALI network.

Sites requiring more than 64 devices can be addressed as DALI subsystem (gateways).
