DIY USB to RS232 Adapter

Sometimes you just need to connect some device to COM port, but computer don뭪 have one especially laptop. There are two ways �?#65533; go and buy USB �?#65533; COM adapter or build one. So if you decided to build USB to COM(RS232) adapter, there is one of solutions. This adapter is very easy to build as there is single chip USB to UART bridge (CP2102) used. This chip from Silicon Labs support USB2.0 full speed, has internal Resistors required for USB interface, integrated clock, internal 1024 -byte EEPROM for vendor ID, Product ID serial number, power descriptor and other information. SP2102 USART part support almost all standard features of RS232 communication including handshaking, Databits (5, 6, 7 and 8); 1 or 2 stop bits; odd, even, mark, space and no parities; baud rate from 300bps to 1Mbits. Device is powered from USB port and requires about 10mA. Chip drivers enable to connect this adapter to most of Operation systems like Win98, Win2000, WinXP, Linux.


USB Switch

USB Switch

USB switch is used to share USB devices such as printers, scanners, hard drivers, etc. between two computers. Just connect the two computers on a network device and say the printer as shared. This method however requires the continued operation of the computer we plugged the printer. Solution to above problem is to give the circuit that we present, and has the potential to be transferred to the printer on whichever computer we want, because the printer is connected to one of two computers, but in construction.


RS232 Serial to USB Converter

RS232 Serial to USB Converter

This is simple RS232 Serial to USB Converter that doesn뭪 need any further explanations. You can use it for any projects that might need it. Diagrams for USB and DB-9 female connectors are provided.


USB-PC 8-CH Power Switch

USB-PC  8-CH Power Switch

PowerSwitch provides 8 bits of parallel output intended to switch e.g. the power supply to electronic devices. The PowerSwitch firmware is accompanied by a command line tool for Unix to control the device. (The command line tool can also be compiled on Windows using minGW and libusb-win32.)


USB LED Load
Posted on Tuesday, April 20, 2010   •   Category: USB Circuts

USB LED Load

The board supports driving two separate tri-color LEDs. More can be setup inline if desired. Currently the software only uses the second LED and its color represents the CPU load of the system in real-time. Blue for idle and gradients light blue, green, yellow, orange, and finally red indicating heavy CPU utilization. If the system fails to respond, the LED begins flashing RED to indicate a lack of communication from the software. This lets you easily identify a crashed machine in a rack for example.


USB - LCD with PIC Microcontroller & FT232

USB - LCD with PIC Microcontroller

USB LCD/VFD Controller is a HD44870 based LCD/VFD controller via USB interface. The control command is compatible with Matrix-Orbital's LCD module. So, you can use any MO friendly software to control this baby. Such as LCDC... The firmware are based on David Potter's Serial LCD/VFD Display, but I almost rewrite the entire code.


USB to RS232 Converter

USB to RS232 Converter

Why build my own USB to RS232 converter when there are adapters already available from many suppler? The Answer is simple: Neither the strand "USB to RS232 converter" actually worked *properly* with all the devices I tried. But, They did not seem to support ALL the RS232 lines. The USB to RS232 converter using the FT8U232AM and a Maxim-IC MAX235


USB to RS232 Dongle

USB to RS232 Dongle

With serial and parallel ports being phased out on new computers, hardware designers and hobbyists have no choice but to convert the USB port back to RS232 serial. FTDI have a very nice chip that does just that, the FT232AM. This chip converts USB to a standard high-speed serial port. The bonus with FTDI is the drivers are already written for you. All you have to do is design the hardware and download the serial USB drivers from FTDI's web site.


USB to RS232 Adapter with FT232

USB to RS232 Adapter with FT232

We employ two UART boards in the course, one which can be connected to the serial connector of the PC (UART-RS232), and a second that can be connected to a USB port (UART-USB). The former is used in the lab and is part of the standard take-home equipment. The latter is part of the (limited!) number of take-home targets for students who are working on a Laptop without serial connector. In both cases, communication is done with the UART module of the microcontroller. In the case of the normal UART board, the MAX232 simply transforms the voltage levels to RS-232 standards (� 3-15V; in our case 12V, with LOW=+12V and HIGH=-12V). In case of the UART-USB, the FT232BM transforms the UART protocol to the USB protocol. This is transparent to the controller, which communicates over the normal TX and RX pins.

USB - Relay Board

Here is the new 6 channel relay USB board to switch different devices, lighting or motors by a computer program via the USB interface.


MAX3420 � Maxim USB Peripheral Controller
Posted on Thursday, April 8, 2010   •   Category: USB Circuts

MAX3420

The MAX3420 is a USB peripheral controller chip with an SPI bus. This page hopefully contains enough information to help you easily make use of the device in your projects. The MAX3420 provides a very simple approach to adding a USB interface to a circuit. It uses a SPI bus to connect to your system. It does require a reasonable amount of configuration and control, so you뭠l need to connect it to some form of microprocessor/microcontroller.


USB Device Charger

USB Device Charger

With this tiny thing you can charge almost all devices that are charged via USB, like iPods or mobile phones, with only two AA-Cells.


USB 8bit Interface Board
Posted on Monday, November 10, 2008   •   Category: USB Circuts

USB 8bit Interface Board

This is a USB (universal serial bus ) interface board which can be used to connect 8 (parallel) data lines to the USB. The interface comes with a small internal FIFO (384 byte Tx, 128 bytes Rx) and 4 handshake lines which make it suitable for interfacing microcontroller designs to the USB. It can, also be used as simple 8bit IO when the so-called 밷itbang mode� is enabled. Note. however, that in this mode, the bits will not come out in a constant bitrate but in chunks of 64 bytes with specified baud rate followed by a delay.
