Introduction
AS7225 Director Demo Kit provides a platform to evaluate ams AS7225 Smart Lighting Director
device. With AS7225 Evaluation User Interface running on Windows based personal computer, one
can control various onboard LEDs and demonstrate the close loop of Color Tuning and Daylight
features. The kit also serves as a development platform that a customer microcontroller can be
used to control AS7225 device as well as onboard LED strings. This user guide describes the
features and functions of AS7225 Director Demo Kit.

Getting Started
The evaluation kit requires one time installation of FTDI CDM Driver for the USB-UART cable if it is
not already installed on the computer. The installation file can be found in the USB Memory Stick. If
there is an issue about the installations, please refer to
www.ftdichip.com
for more information.
The AS7225 Evaluation User Interface software does not need extra installation. Please copy the
following files to any folder you would like to work with and run the .exe file to start the GUI.

Power Supplies
The AS7225 Director Demo Kit is powered by 12V wall plug power adapter. The 12V supply
provides the power to the LDOs as well as MOSFETs and LEDs circuitries. Onboard LDO U1 has
3.3V output, which is used for AS7225, Flash Memory, onboard MCU, and J6 for external sensors.
The 3.3V can be also connected to customer microcontroller through J2. LDO U2 has 5V output
and is connected to J3 for customer development purpose. Each LDO could deliver upto 200mA
total current.
