Smart lighting fixtures controlled via mobile phone WiFi

This project is a
school electronics technology internship. The initial design was done in Altium Designer (AD), and later redesigned using JLCPCB. The number of components used is relatively small, and the finished product is not difficult.
1. Project Description
1.1 Project Overview
This project uses 12 yellow and 12 white LEDs, along with a BL-M5-WIFI wireless module. Product development is possible without requiring WIFI firmware development, APP development, or cloud server development.
1.2 Project Functionality
After the PCB is fabricated, soldered, and debugged, connect the power supply. Download Magic Home Pro on your phone, connect to the chip's WiFi (LEDnet***), and you can control the bulbs from your phone.
1.3 Physical Demonstration
(Functional demonstration at the end
) 2. Hardware Description
2.1 Power Supply & Wireless Board
1) Wireless Module BL-M5-WIFI, model BL-M5_L52_CCT, PWMW is a warm white PWM output, PWMC is a cool white PWM output, connected in series with a current-limiting resistor and a pull-down resistor.
2) AMS1117-3.3, converts 5V to 3.3V.
2.2 Lamp Board
1) SM15633E, a three-channel LED constant current driver control chip, can achieve dimming of OUT1/2/3 ports by inputting PWM signals through DIM1/2/3 ports respectively.
2) Surface Mount Single Row Female Socket GL04B008SFR-002 (4P2.0), which can be paired with the power board to provide power and PWM wave to the lamp board.
3) QM52, QM82, two different sizes of jumpers. Because this project will teach PCB etching later, the PCB can only be drawn on one layer. Jumpers are used for places where it cannot be drawn.
4) Surface Mount LED2835WA cool white light, Surface Mount LED2835EA warm white light
. 3. Instructions for Use
The casing is provided by the school. You need to find a USB cable to solder the 5V and GND pads on the power board. After powering on, you need to download the APP (Magic Home Pro download address) to control the brightness and color temperature.
The attachment contains the component manuals for the lamp board, power supply & wireless board. The course materials teach how to draw those two boards in AD.
