{"title":"SparkFun 16x2 SerLCD - RGB Text (Qwiic)","handle":"sparkfun-16x2-serlcd-rgb-text-qwiic","url":"/products/sparkfun-16x2-serlcd-rgb-text-qwiic","description":"The SparkFun 16×2 SerLCD is a serial-enabled LCD that provides a simple, cost-effective way to add an RGB-on-black liquid crystal display to your project. An on-board ATmega328P microcontroller handles all screen control, eliminating the need for a separate backpack board.\n\nThe display supports three communication interfaces — serial (UART), I2C, and SPI — and includes a Qwiic connector for quick, solderless I2C connections. The open-source firmware allows full customisation of the display behaviour.\n\nKey Features\n\n\n16×2 RGB on Black Display – Clear, readable text with customisable RGB backlighting\n\nTriple Interface – Serial (UART), I2C, and SPI communication options\n\nQwiic Connector – Polarised 4-pin JST connector for solderless I2C hookup\n\nOn-Board Controller – ATmega328P with 11.0592 MHz crystal for accurate communication\n\nAdjustable Baud Rate – 1200 to 1,000,000 baud (default 9600)\n\nOpen-Source Firmware – Fully customisable to suit your project needs\n\n\nSpecifications\n\n\nDisplay – 16×2 character LCD, RGB on black\n\nController – ATmega328P AVR\n\nCrystal – 11.0592 MHz\n\nInterfaces – Serial (UART), I2C (Qwiic), SPI\n\nDefault Baud Rate – 9600\n\nOperating Voltage – 3.3V\n\n\nIdeal For\n\nDisplaying sensor readings and system status\nArduino, Raspberry Pi, and microcontroller projects\nData logging and monitoring dashboards\nPrototyping with the Qwiic I2C ecosystem\n\n\n\nWarning: The SerLCD is a 3.3V device. If using a 5V microcontroller, ensure you use appropriate logic level conversion to avoid damaging the display.\n\n\nResources\n\nHookup Guide\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3890,"title":"Default Title","sku":"SF-LCD-16397","price":74.25,"on_sale":false,"in_stock":true,"available_quantity":36,"option1":"Default Title"}]}
