USB Input / Output Board is a quick little development board which replace parallel port . USB IO Board is compatible with Windows computers on HID class which means direct plug like USB mouse or keyboard . When attached to Windows IO board will show up as Found new hardware “Microembeded USB IO” and get installed automatically. You can control 16 individual microcontroller I/O pins by click of a button or entering the hex value of the two 8 bit ports. USB Input / Output Board is self-powered by USB port and can provide up to 500mA for electronic projects. USB IO Board is breadboard compatible. Simply solder included 8-PIN headers on PCB and the board can be plugged into a breadboard for quick prototyping.

Homemade USB interface board using a PIC

This is a USB interface board I’ve built around a PIC 18f4550 microcontroller from Microchip. As many of you probably know, I’ve used my computer’s parallel port to connect many things to my computer. However, most laptops don’t have parallel ports these days, so I needed a way to connect things without a parallel port. This board does exactly that (and actually much, much more). I found a really nice tutorial on building this board here – http://eegeek.net/content/view/13/32/

Build a USB device with a PIC

PIC 18F4550 and 18F2550 are powerful microcontrollers including a full-speed USB V2.0 compliant interface. With these MCU it’s very easy for the hobbyist to design USB devices with very few components. In these pages, I’m describing how to use the CDC firmware from Microchip. It permits to emulate a serial port with a PC running Windows or Linux. It’s also very easy to build HID devices.

Bi-color LED matrix clock

This project is a clock that is using a Bi-Color LED matrix display to show the time. The clock is driven using two 74595 chips for the columns and a pair of ULQ2003 chips for the rows and it is based on PIC 18F4550 . Control of the clock is done via USB, and takes care of lighting up the hour as a red number when it’s time to sleep, and a green one when it’s okay to arise .danielparnell.com writes: [via]

I wanted to make the whole thing fit behind the display, so I was forced to put the processor and the LED driver hardware on their own boards.

18F4550 USB Proto Board

This board is a Microchip PIC prototyping board for the 18F4550 microcontroller using USB. It is designed to have the PIC loaded with a USB bootloader and then a separate programmer is no longer needed. The board has all the circuitry needed for a successful USB interface. Free I/O pins have 1-3 solder pads for easy connection for prototyping. This board is based on the one I use for all my own USB experimentation, and is compatible with the firmware and software in my 18F4550 USB Interface article, my PIC USB Bootloader article, and others. It should also work fine for other PIC USB interfacing projects, such as HID or CDC (virtual COM port) applications.
