Description Links Attachments

The SparkFun SerLCD is a serial enabled LCD based on AVR technology, offering a cost-effective solution for integrating a 16x2 Black on RGB Liquid Crystal Display into your project. It features an enhanced PCB design on the back of the screen, including an ATmega328P that manages all screen control, eliminating the need for a backpack. The display can communicate via serial, I2C, and SPI, and is equipped with a Qwiic connector, which simplifies wiring and allows your project to display various types of text and numbers.

The embedded ATmega328P AVR microcontroller uses an 11.0592 MHz crystal for enhanced communication accuracy, with adjustable baud rates ranging from 1200 through 1000000, though it is default set at 9600. The firmware for this SerLCD is fully open-source, allowing for any customizations you may need.

Keep in mind that the SerLCD is a 3.3V device. Always convert to 3.3V logic based on your chosen microcontroller or single-board computer to avoid damaging your board.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that streamline prototyping and minimize errors. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, which reduces the required PCB space. Plus, the polarized connections mean you can't connect it incorrectly.

This LCD screen features a 16x2, Black on RGB Display and three communication options: Serial, I2C, and SPI. It has an adjustable I2C address controlled via software special commands, an operational backspace character, and an incoming buffer that stores up to 80 characters. The pulse width modulation of backlight allows direct control of backlight brightness and current consumption, while the pulse width modulation of contrast allows for software-defined contrast amount. The open-sourced firmware and Arduino-compatible bootloader enable updates via the Arduino IDE. The input voltage is 3.3V-9V, and the I/O logic levels are 3.3V. The dimensions are 80.29mm x 35.90mm x 14.09mm, and it weighs approximately 2.17 grams.
