	UVNC1 USB Host development kit




		UVNC1 Host kit shown assembled

UVNC1 USB Host development board based on the FTDI Vinculum VNC1L chip. The board has one USB Type A connector and provisions for a second on. The board also has a 3.3v (the RS232 lines are 5v tolerant) Serial TTL header for communication via RS232 or SPI with any mcu. The VNC1L chip is reprogrammable with firmware and utilities from Vinculum web site, www.vinculum.com . Documentation and sample applications are also available from their site. Using simple commands one can read, write, delete, files and folders on most USB flash drives, like those used with notebooks and PC’s. The kit has on on-board 5v and 3.3v regulators. USB devices that are connected to the board are provided with 5v @ 100ma Easy to serially interface with microcontrollers!

The VNC1L chip documentation, firmware and programming applications are available for free at www.vinculum.com

The VNC1L chip provided is blank and will have to be programmed after the board is assembled. All programming files and firmware is available free at the Vinculum website

	Construction Hints


	Assembly of this kit requires that the user has the necessary tools and skills to work with SMD (surface mount device) components. If you are not comfortable with soldering miniature parts, then please seek assistance from someone who is capable to do so. Small mistakes can cause many frustrating hours of grief in trouble shooting!.


	Minimum tools required: A fine point low power (25w max) soldering iron and thin solder. Ideally, 0.022" diameter (or less) silver-bearing non-corrosive rosin core should be used. In addition. narrow needle nose pliers, diagonal cutting pliers, good quality tweezers, large magnifying glass, volt-ohm meter, and a 7 to 12 vdc power supply.

Make sure that you work in a clean well lighted area and have adequate desk area. If you have carpeting then please be aware of static discharge as well as accidentally losing tiny components in the carpets fiber. SMD capacitors and resistors are very tiny and can quickly become lost in the carpeting
