We've seriously overhauled the PCB design on the back of the screen by including an ATmega328P that handles all of the screen control, meaning a backpack is no longer needed! This display can now communicate in three different ways: serial, I2C, and SPI. This version comes equipped with a Qwiic connector, bringing serial LCDs into the Qwiic ecosystem. This simplifies the number of wires needed and allows your project to display all kinds of text and numbers.\u003c\/p\u003e \u003cp\u003eThe onboard ATmega328P AVR microcontroller utilizes 11.0592 MHz crystal for greater communication accuracy with adjustable baud rates of 1200 through 1000000 but is default set at 9600. The firmware for this SerLCD is fully open-source and allows for any customizations you may need.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNote: Since the SerLCD is a 3.3V device, please make sure you convert to 3.3V logic depending on your chosen microcontroller or single-board computer. Otherwise, you may risk damaging your board.\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/avr-based-serial-enabled-lcds-hookup-guide?_gl=1*wy8hhk*_ga*NDYwMjM5MTMxLjE2NzIyNDIzODQ.*_ga_T369JS7J9N*MTY5MDM2MDQ0Mi4xMi4xLjE2OTAzNjE2MzEuNTkuMC4w\u0026amp;_ga=2.236144961.1749837618.1690360442-460239131.1672242384\"\u003eGet Started with the Sparkfun SERLCD Guide\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/vyjXRYAXahY?start=16\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e \u003ch2\u003eFeatures\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e16x2, Black on RGB Display\u003c\/li\u003e \u003cli\u003eThe AVR ATMega328p (with Arduino-compatible bootloader) is populated on the back of each LCD screen and handles all of the LCD control\u003c\/li\u003e \u003cli\u003eThree communication options: Serial, I\u003csup\u003e2\u003c\/sup\u003eC and SPI\u003c\/li\u003e \u003cli\u003eQwiic connection\u003c\/li\u003e \u003cli\u003eAdjustable I\u003csup\u003e2\u003c\/sup\u003eC address controlled via software special commands (0x72 default)\u003c\/li\u003e \u003cli\u003eEmergency reset to factory settings (Jumper RX to GND on bootup)\u003c\/li\u003e \u003cli\u003eOperational backspace character\u003c\/li\u003e \u003cli\u003eIncoming buffer stores up to 80 characters\u003c\/li\u003e \u003cli\u003ePulse width modulation of backlight allows direct control of backlight brightness and current consumption\u003c\/li\u003e \u003cli\u003ePulse width modulation of contrast allows for software-defined contrast amount.\u003c\/li\u003e \u003cli\u003eUser-definable splash screen\u003c\/li\u003e \u003cli\u003eOpen-sourced firmware and Arduino-compatible bootloader enables updates via the Arduino IDE\u003c\/li\u003e \u003cli\u003eInput voltage: 3.3V-9V (3.3V only via Qwiic connector and \"+\" pin)\u003c\/li\u003e \u003cli\u003eI\/O logic levels: 3.3V\u003c\/li\u003e \u003cli\u003eCurrent consumption @ 3.3V \u003cul\u003e \u003cli\u003eMinimum with no characters \u003cul\u003e \u003cli\u003e4.4mA (LEDs off)\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eMaximum with all character spaces filled \u003cul\u003e \u003cli\u003e11.9mA (red)\u003c\/li\u003e \u003cli\u003e8.9mA (green)\u003c\/li\u003e \u003cli\u003e8.1mA (blue)\u003c\/li\u003e \u003cli\u003e19.6mA (white)\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eDimensions (LxWxH): 80.29mm x 35.90mm x 14.09mm\u003c\/li\u003e \u003cli\u003eWeight: 0.0766 oz.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eResources\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/avr-based-serial-enabled-lcds-hookup-guide?_gl=1*1e8ry16*_ga*NDYwMjM5MTMxLjE2NzIyNDIzODQ.*_ga_T369JS7J9N*MTY5MDM2MDQ0Mi4xMi4xLjE2OTAzNjE5MTguNTQuMC4w\u0026amp;_ga=2.36438240.1749837618.1690360442-460239131.1672242384\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/OpenLCD\/blob\/master\/firmware\/OpenLCD\/OpenLCD.ino.arduino_standard.hex\"\u003eFirmware Hex File\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/OpenLCD\"\u003eGitHub Firmware Repo\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/learn_tutorials\/7\/8\/9\/SerLCD_Qwiic_16x2_Dimensions_Top_Down.pdf\"\u003eDimensional Drawings (PDF)\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eand\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/learn_tutorials\/7\/8\/9\/SerLCD_Qwiic_16x2_Dimensions_Top_Down.png\"\u003ePNG image\u003c\/a\u003e\n\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/sparkle.sparkfun.com\/sparkle\/file_store\/parts\/15122\/10\/2022-03-08_08:10:48\/PN%2015122%20-%20Schematic%20March%202022.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/Qwiic_SerLCD_Py\"\u003ePython Support (Qwiic_Py)\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":50847614927121,"sku":"LCD-16396","price":22.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/sparkfun-16x2-serlcd-rgb-backlight-qwiic-sparkfun-lcd-16396-40710016368835.jpg?v=1735216556","url":"https:\/\/abcd3032.myshopify.com\/zh\/products\/sparkfun-16x2-serlcd-rgb-backlight-qwiic","provider":"Tayyab Zak","version":"1.0","type":"link"}
