Well, we've solved that problem by making them a little bit \"smarter.\" The SparkFun 7-Segment Serial Display combines a classic 4-digit 7-segment display and an ATMega328 microcontroller allowing you to control every segment individually using only a few serial lines.\u003c\/p\u003e\n\u003cp\u003eThe Serial 7-Segment Display can be controlled in one of three ways: Serial TTL communication, SPI serial communication or I2C serial. You can even program it for stand-alone operation since the ATMega328 comes pre-loaded with the Arduino bootloader! There is also an FTDI header on board and we've provided a hardware profile for the Arduino IDE to make it even easier to program.\u003c\/p\u003e\n\u003cp\u003eWe've made some layout changes to this design as well which will make it easier to incorporate these into your project. We've moved the power and I2C pins to the sides of the board such that you can chain them together in order to display longer strings of digits. We've also added mounting holes to the boards so you can mount them on standoffs (no more hot glue!)\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4 digit red alpha-numeric display with TTL, SPI or I2C Serial Interface\u003c\/li\u003e\n\u003cli\u003eDisplay numbers, most letters, and a few special characters\u003c\/li\u003e\n\u003cli\u003eIndividual control of decimal points, apostrophe, and colon\u003c\/li\u003e\n\u003cli\u003eSelectable baud rate\u003c\/li\u003e\n\u003cli\u003eSelectable brightness\u003c\/li\u003e\n\u003cli\u003eBaud rate and brightness values retained in non-volatile memory\u003c\/li\u003e\n\u003cli\u003eIndividual segment control for each digit\u003c\/li\u003e\n\u003cli\u003e41mm x 23mm (1.6in x 0.9in)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eEagle Files\u003c\/li\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003cli\u003eHookup Guide\u003c\/li\u003e\n\u003cli\u003eArduino Add-On\u003c\/li\u003e\n\u003cli\u003eGithub Repo\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":53636164911397,"sku":"ifu1787258040729","price":10.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/6251\/1397\/files\/sparkfun-7-segment-serial-display---red_1.jpg?v=1787258049"},{"product_id":"sparkfun-picobuck-led-driver","title":"SparkFun PicoBuck LED Driver","description":"\u003cp\u003eThe PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analogue voltage or a PWM signal to the board.\u003c\/p\u003e\n\u003cp\u003eVersion 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board, allowing it to be used up to the full 36V rating of the AL8805 part.\u003c\/p\u003e\n\u003cp\u003eThree signal inputs are provided for dimming control. You can use the PWM signal from an Arduino or your favourite microcontroller to dim each channel individually, or you can tie them all to the same PWM for simultaneous dimming. Dimming can be done by an analogue voltage (20%-100% of max current by varying voltage from .5V-2.5V) or by PWM (so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V) for a full 0-100% range. A small jumper is provided for each channel to allow you to increase the drive strength from 330mA to 660mA. Two mounting holes for 4-40 or M3 screws are provided on either side of the board. They are perforated so they can be easily snapped off with a pair of pliers if a smaller footprint is desired.\u003c\/p\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIf you're going to use screw terminals, this board uses two different sizes (2.54mm 2-pin, and 2.5mm 2-pin).\u003c\/li\u003e\n\u003cli\u003eThe PicoBuck LED Driver was made in collaboration with Ethan Zonca.
