For Auction: New Design PCB for the N3ZI digital dial ( See the N3ZI website for all of the details of this truly innovative Digital Dial project ). This board , as with the original, is designed to use readily available components ( sources include Jameco, Digikey, Mouser), and a parallel 44780 LCD display (available on Ebay as well as the parts sources quoted) . Bare board only, no other parts supplied or included. The programmed U3 is available from N3ZI ( see their website) for a very nominal cost. An assembly manual , including unit schematic, is supplied at time of sale ( Email, PDF document) along with suggested part numbers from Jameco. ( We would post links for the various sites mentioned but links are not allowed). *** Pricing: 1st Board is $5, subsequent boards are $4 ea, PP to the Lower 48. **** ***** Fully assembled digital dial / counter available ***** email for details. ************************ Features ************************** Programmable IF frequency, and VFO mode (VFO+IF, VFO-IF, IF-VFO) Supports up to 9 different IF offsets S/W Programmable to accommodate /n prescaler (n can be 2,4,8,16) On board voltage regulator allows normal operation from 11 to 15VDC power source. Battery operation possible by bypassing on board regulator, ~3mA at 3-5 VDC 2 pushbuttons required only for programming IF and Formula. All programmable options stored in non volatile EEPROM, so they only have to be set once. Input Sensitivity: typically 150mV RMS uCode, includes anti jitter s/w which prevents LSD from jittering between two values. Measures VFO frequency up to 60 Mhz with Div/16 prescaler. ( 80mhz possible with hand selected U2 74HC163) 32 bit internal math 100 Hz or 10 Hz display resolution. No XTAL trim cap required, correction applied in S/W. Update rate approx. 20 ms w/o prescaler. 80 ms with /4 prescaler. NO soldering of Surface mount components required. Standard LCD has Large 0.375 inch digits, dimensions 4.88 x 1.25 inch Supports many different 3rd party LCDs Supports 14-16 pin 44780 LCD Modules w/ either 2 row or single row connector On board driver for LED backlight Up to 20mA when using the 78L05 regulator in a TO92 package Up to 100mA when using the 7805 in a TO220 package, no heatsink Up to 250mA when using the 7805 in a TO220 package, with heatsink Skill level required : Some soldering and mechanical skills. The N3ZI Digital Dial is designed to add precision to a wide variety of Ham Radio units ( See the N3ZI website for all of the exciting details) as well as serve as a stand alone frequency counter . Programmable IF, easy assembly, installation and a number of other features make the N3ZI digital dial a very useful project. Skill level Shipping is via USPS , (FREE) to the lower 48. Worldwide shipping is also USPS priority mail ( not free). This auction is for One (1) board, however discounts are available for multiple board purchases. All sales are final: no guarantees or warranties expressed or implied. No returns or exchanges. As with all printed circuit boards , some care while soldering is required and of course the use of a low wattage or temperature controlled soldering iron. Photos show Component and Reverse sides of board and are THE board you will receive. No Serial Number. ~~~~~~~~~~~~> http://www.ebay.com/usr/cornelius_connie <~~~~~~~~~~~~~~~~~~~~ About us !
