![]() ![]() To ease you into the production world we have developed a platform ( PCB CUPID) for PCB enthusiasts and hobbyists to ask and answer questions related to PCB design, fabrication, and assembly. Getting a electronics project into production would be nightmare. Step 4: Putting Everything Together With ESP-12E You can check the circuit diagram for a more detailed connection. This will setup the power for the SD card. Finally, solder the pin 3 (output pin) and ground of the regulator to the SD card. To solve this we'll use a 3.3V regulator and connect the input of the USB supply to 3.3V regulator i.e connect GND of the USB to pin 1 of the regulator and connect pin 3 of the regulator to +5V of the regulator. This did not solve any power issue yet! Because the SD card requires 3.3v but the USB supply is standard 5V if you just plug this in the supply, you will probably fry out the SD card ( But no damages will be taken by the microSD adapter ). ![]() Then placed the male USB port in front of the SD card where we made some space earlier, then solder it in place. Since we just need power, I will cut data pins and just keep the GND and VCC. This usually has 4 pins, where 2 middle pins are used for data transfer and 2 extreme pins are used for power and ground. We need to power the SD card, For that, we'll be using the USB receiving port itself. These are the list of products which can help you do this project with ease With this setup, we can copy as well as save files to the SD card wirelessly! This fulfilled all my wishes, all I have to do is to just plug it inside any USB receiver, it doesn't matter which one!Īs soon as you plug it in, it creates an access point where we can connect and then connect to the access point and just open up any FTP client application in any compatible device. There are so many different variants of these USB ports which is so frustrating at times and the way these works totally contradict their name because Every USB receiver should be compatible with any USB device! You can't plug in your USB stick or a keyboard inside a charger and expect it to work.īut the concept sounds too good! That's why to initiate this " Universal-Port " concept I started with a simple project " Wireless Card reader " ![]() USB was supposed to be universal, and the main goal was to make a hot-swappable, super easy to interface with other devices but over the years the idea went haywire. ![]()
