The USB interface shows up as a COM\/serial port on Windows\/Mac\/Linux. The backpack will automatically select data from whichever input is being used. For the USB connection, it will work at any baud rate. For the TTL connection, the default baud rate is 9600 but you can send it a command to set the baud rate to 2400, 4800, 9600, 19200, 28800, or 57600 baud. (The baud rate is flashed on the LCD during powerup). Any customizations such as baud rate, backlight color, brightness, splash screen, etc. are stored permanently EEPROM.\u003c\/p\u003e\n\u003cp\u003eThe command interface is compatible with the popular \"Matrix Orbital\" specifications so this backpack will work perfectly with computer applications or libraries that are expecting a \"Matrix\" LCD such as \u003ca href=\"http:\/\/lcdsmartie.sourceforge.net\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\"LCD Smartie\"\u003c\/a\u003e. Adafruit added a few extra commands for the RGB backlight and setting the LCD size. If you don't want to use the commands, you can just start sending ASCII to the LCD and it will magically appear as typed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes not include an LCD module! \u003ca href=\"\/en-eu\/search?type=product\u0026amp;q=lcd\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eYou'll need to pick out an LCD from the shop and solder it on the back.\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTECHNICAL DETAILS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBackpack details:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with any 'standard' 16x2 or 20x4 character LCD as well as any Adafruit RGB LCD.\u003c\/li\u003e\n\u003cli\u003eFull PWM backlight control\u003c\/li\u003e\n\u003cli\u003eSupports the following Matrix Orbital commands:\n\u003cul\u003e\n\u003cli\u003eAutoscrolling\u003c\/li\u003e\n\u003cli\u003eBaud rate adjust\u003c\/li\u003e\n\u003cli\u003eClear screen\u003c\/li\u003e\n\u003cli\u003eChange splash\u003c\/li\u003e\n\u003cli\u003eAuto-wrap\u003c\/li\u003e\n\u003cli\u003eSet cursor\u003c\/li\u003e\n\u003cli\u003eHome\u003c\/li\u003e\n\u003cli\u003eMove cursor\u003c\/li\u003e\n\u003cli\u003eUnderline\/Block cursor\u003c\/li\u003e\n\u003cli\u003eCreate custom characters\u003c\/li\u003e\n\u003cli\u003eSave custom character bank\u003c\/li\u003e\n\u003cli\u003eLoad custom character bank\u003c\/li\u003e\n\u003cli\u003eDisplay On\/Off\u003c\/li\u003e\n\u003cli\u003eSet brightness\u003c\/li\u003e\n\u003cli\u003eSet contrast\u003c\/li\u003e\n\u003cli\u003eGeneral Purpose Outputs (4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupports extended Adafruit commands:\n\u003cul\u003e\n\u003cli\u003eSet RGB backlight\u003c\/li\u003e\n\u003cli\u003eSet LCD size (up to 20x4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/usb-plus-serial-backpack\/downloads\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSchematic, GitHub link, and Fritzing available in the product tutorial\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eProduct Dimensions: 54.0mm x 29.0mm x 7.3mm \/ 2.1\" x 1.1\" x 0.3\"\u003c\/p\u003e\n\u003cp\u003eProduct Weight: 6.8g \/ 0.2oz\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":32694168586,"sku":"ADA781","price":12.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/781.jpg?v=1539264526","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-usb-serial-lcd-backpack-add-on-with-cable","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
