Description: Hardware emulating the Classic HP CalculatorsBuild a fun, educational easy to build calculator. Features:All Through Hole parts. (easy to handle and solder)Runs about 4 to 5 times faster than the original (voyager series). Memory registers: same memory as the original.Continuous memory (Memory is not lost when calculator is turn off).Auto power offRuns on a single ATMEGA328 8 bit microcontroller running @ 8MHz (same as Arduino Uno)Speaker for audible keypress feedback192x64 lcd displayDisplay BacklightHas a real time clock. (Uses a 32.768KHz crystal)Uses a single CR2032 3V battery.Power consumption: 1µA off, 350µA idle, 3mA working (this is with speaker and backlight off) Can run any of the Voyager series and HP41C calculators, with the appropriate firmware. In programming mode, the names of the keys are displayed on the header of the display.It's a bit smaller than the original - 4.2" x 2.67" (10.668 x 6.7818 cm).More info at voyager.You will receive the following:PartQTYValueDescriptionC1, C220.1µfDecoupling CapacitorC310.1µfSpeaker impedanceU11ATMEGA328PPreprogrammed MicrocontrollerJ116 pin female headerSPI Programing headerBAT1Battery HolderCR2032 Battery HolderSPK1BUZZERSpeakerXTAL1Clock Crystal 32.768kHzClockR1110KΩReset pullup resistorR2110ΩLCD backlight resistorBTN's396x6mm tactile switchKey buttons, (11mm tall)RST16x3.5 mm tactile buttonReset buttonPCB1PCBPCBDISP1Display 192X64 LCDDisplay19 pin male headerFor Mounting Display1double sided tapeto attach display to microcontroller.4rubber feetrubber feet1Bumper3D printed bumper1Bat Holder3D printed Battery Holder2PanelTop and bottom panels1hardware Kitbrass posts & screwsPanels are made from standard FR-4 PCB.
