GeeekPi LCD 2004 Module with I2C Interface Adapter Blue Backlight 2004 20x4 LCD Module Shield for Raspberry Pi Arduino Uno

The LCD has always been a device that acts as a window in human-computer interaction. For example, the prompt window on some instrument devices, the....
The common LCD1602, LCD2004, and LCD12864 are fabricated using liquid crystal materials and communicated using the I2C bus..
It is a high-performance serial bus with bus rules and high-speed or low-speed device synchronization required for multi-master systems. The I2C bus....
Compatible with all devices with I2C interfaces, such as Arduino, raspberry pi, beagle bone black, tinker board, stm32, esp32 and more..
Package Includes:1 x LCD2004,1 x Jumpwire.

Support a Variety of Stepper Drivers -- 2560 and Ramps 1.4 are integrated in the board, which avoids the problem of complicated connectors and malfunctioning. Support a variety of stepper drivers such as A4988, DRV8825, TMC2100, available to change the stepper drivers and motors as users like..
Reserve External Driver Signal -- available to connect external high-current driver to drive the 57 and 86 stepper motors. Use high-quality MOSFET, better cooling effect and more stable. Use specific power chip, support 12V-24V power input, and resolve t..
Use CH340 Serial Port Chip -- Stable and reliable filter circuit greatly reduces interference and avoids crashes as possible in the process of printing. Use CH340 serial port chip, more easily install the drive than 16U2..
Support 24V Input -- The heated bed current can be reduced to 1/4 at the same system power which effectively resolves the problem that the MOSFET of heated bed heats. Run Marlin firmware, the configuration is completely same as Ramps 1.4..
Compatible With -- Support Ramps 1.4, 2004LCD,12864LCD, TFT28 and TFT32. X-axis, Y-axis and Z-axis with different color terminal controls the stepper motors and endstops, which is convenient to wire..
