Type device IP, choose baud rate, stop bit, data bits, parity and click "Connect" button. On your PC connect to “dihavSerialPort_XXXXXX” access point, device IP address in access point mode is “192.168.4.1”.ĭownload the Windows application I uploaded here, and execute it on your PC. Plug AC adapter output into "Serial Port over WiFi” DC input connector. According to LF33CV datasheet, you can power this device from 3.5VDC to 18VDC.Ĭonnect 3.5mm audio connector to the serial port of target device, and male power connector to the power supply of target device. I placed two connectors for the power supply (one male and one female) to be able to put this device easily between AC adapter output and the set that must connect to the serial port, so you have not to prepare another power source for this device. The video shows controlling an E-waste CNC (3D printer) using this device. Wow, I just wanted a wireless serial port, now I also have a serial port over the web. Is it possible to have the serial port on the air like wireless mice and keyboards? Of course, it can be done using lovely WiFi module ESP8266, and by using WiFi you have not to make a dongle yourself and also you can have a serial port over the internet. It works very well, but long wires from devices to PC are annoying me. Then I decided to make a USB-TTL UART adapter using famous FT232 IC for my projects. But I faced a new problem, new motherboards and laptops have no COM port. So I made an RSS232-TTL UART adapter and published here to uses in all of my projects. Another easy way is Serial Port (aka COM) and RS232 protocol that only needs a tiny electronic circuit to convert voltage levels and a little programming. But transmitting data over USB requires lots of programming. When talking about connecting a device to PC, the most obvious way of communicating is USB port. connecting your microcontroller to PC and monitor data on a large colorful display instead of small monochrome LCD. Data communication between electronic devices is inevitable in many electronic projects and brings a lot of advantages to your project i.e.
