R2 changes: -Moving to Letter Modules for ease of design -Adding ESP32 for WiFi On/Off and intensity control -Optional: Add unpopulated AA Battery Holder for battery option R1 changes: -Changed LED part to Red LEDs -adjusted resistor value of buck converter -Changed source for USB-C Connector -Removed exposed soldermask on buck converter with negative soldermask expansion -Order with black soldermask Modified by markwu2001: - Adjustable Brightness, - 85-90% Drive Efficiency - <5W Operation (Can use 5V 1A Plug) This project can be purchased from LCSC Original Description: Daddy's second circuit board. A sign to let my wife know when I'm on a call. Activates with a slide switch and is powered by USB-C. #template

I want make a board that trigger a green and red LED with three wire, 0V, 24V and output of proximity switch. but i want output wire remain 0V when not connected.

This is a diode-based VCA audio compressor that works in mono. The compressor has LED-based gain reduction metering, input gain (preamp), output gain, and a fast-attack switch akin to the SSL channel-strip compressors. The module is to be powered by a regular outlet so it has an AC-DC converter.

Constellation PCB - Meant to blink LEDs representing the constellation Cassiopeia - On/off switch for controlling the LEDs and switches to control the colors of the LEDs

This is a reference design of buck based on LT1933 with an internal 0.75A power switch and 3.3V output #3V3 #dcdc #power #referenceDesign #powermanagement #analogdevices #template

MAX6675 Module and Stepper Motor Driver (e.g., A4988a with a esp32 it has to be contolled by cloud and manual switch

This Device can switch 5 outputs, have 5 momentary inputs, a FS1000A tx and MPU6050

This is a speech output model for a NIFPES (Nitrogen Injection Fire Prevention and Exhaustion System) machine. ESP32 is being used where it is connected with a limit switch LXW20-11M and ESP32 is connected with DFPlayer mini MP3 Speaker module and the speaker module is further connected to a speaker. This model is powered by a PLC SMPS of 24V and is connected to the door of the control panel of the machine. Function:- Now whenever the door is opened or closed, there is a speech output from the speaker "The door is open" or "The door is closed". Further work to be done:- I need to integrate the fire alarm signals and 20 more signals of 24v each from the PLC output to the ESP32 so that there can be speech outputs whenever any signal is high.
