it is for a USB connection to send and receive data to a thermal label printer

Hi I have requirement to create PCB design for my project. My project is currently using ESP32 DEVKITv1 () connected to 2 sensors to get input data. The ESP32 Devkit is also conected to a 5v single relay. As currently relay and ESP32 DEVKITv1 are separate components connected via cables, I need the single custom PCB which will should have 1) all the components from standard ESP32 DEVKITv1, except USB power. 2) Relay should be mounted onto PCB and relay should be conteollable by ESP32. The PCB should hae capability to connect relay to external motor to turn ON or OFF 3) The power input, data input and data output support should be there for PCB 4) The PCB should also be capable to support power 3.3v for 2 sensors.( Sensors

...live stream video coming from the video source to other Android devices. We unfortunately cannot make changes in our app, so we would instead like to create a custom version of Android that has a "special" native camera input which really is just this HDMI video source/drone. Technical implementation I imagine that we could use a UVC capture card such as AVerMedia to convert that HDMI signal to USB-C that the Android OS can "understand". I have imagined that we could create a special camera or something similar that any app can use where the video feed from the drone would be used. Accept criteria - Our app should show the drone video as a camera option in the app. - Our app should be able to live stream the video - Sound from the HDMI should be supported -...

I have developed a PCB module. I need someone to design the enclosure for this PCB, with holes to screw the PCB to the enclosure bottom and for fixing the enclosure to the surface (will be mounted on an MS Plate). A clearance of at least 10mm required on both the top and the bottom of the PCB. Space required on the side of the enclosure to access the input and output terminals and for the Micro-USB port. I will print the design on my Ender 3 3D Printer using PLA.

Hello, We are looking to build a local website that controls functions on a hardware relay switching board. This is the board we are using: The host computer runs Denkovi Relay Command Line Tool, which allows us to control the relay via command line, or with simple commands using shell_exec() : in PHP. Please review this page and see the bottom where it says PHP for documentation notes: What we are looking to do here is create customizable functions where we run certain relays for a certain amount of time. We need a custom GUI with the ability to add new functions. For example, if we want one button to turn on Relay 1 for 200 milliseconds, then turn off Relay 1,

Hello, We are using this relay board: See that page for some code examples. We would like to control the relay board from a local webpage (html front end). The front end can just be a simple list of relays 1-16 with an on button and off button to send the commands Commands for single relay setting: "01+//" - Relay 1 is switched ON "01-//" - Relay 1 is switched OFF "02+//" - Relay 2 is switched ON "02-//" - Relay 2 is switched OFF ...... ...... "16+//" - Relay 16 is switched ON "16-//" - Relay 16 is switched OFF There are some VB examples as well there if you would like to go that route. You will have full remote access to the local machine connected to the relay board to test.

...show idea is an arrangement for a few, it's the triple camera on the back that we would need Apple to take a leaf from. The camera exhibit is incredibly smooth, no camera knock to show. Apple has a slight camera swell in iPhone 13, in iPhone 14 we couldn't want anything more than to see that go level along the telephone's back. Apple actually stays determined with changing from lightning port to USB-C, which European Union basically is pushing to turn into a norm for all organizations to follow. There were bits of gossip at first that iPhone 13 could be a port-less gadget, depending on MagSafe charging totally. It hasn't occurred for this present year, and ConceptsiPhone accepts, it won't be the situation with iPhone 14 either; yet the new gadget could ...

I have a program written in C# with its source program takes a binary file as an input and encrypt it then send it through usb serial communication to a canbus device. I have lost the binary that I used but I still have the source code of the C# program so I want someone to read the source code and the canbus encrypted binary data and figure out all the steps taken to encrypt the binary in order to make some function to generate the unencrypted binary You have to be familiar with c# and canbus is an added skill that can help but not that you can figure out what the program is doing only by reading the source code and seeing what it does to the input binary The payment will be only if the job is is by inputing the resulting file that you generated
