GTM32 is fully self-developed, open source control board by Geeetech for high-performance 3D printers. It keeps Geeetech’s uniformly optimized interface specifications, easy to assemble and with compact layout, high integration and high performance.

GTM32 control board (hereinafter referred to as the control board) adopts the current mainstream high-performance Cortex M3 core chip STM32F103, with its running frequency of up to 72MHz.The control board supports up to 6 stepper motors, namely, XYZ axial motors and 3 extruders. Users can replace the driving modules, such as A4988 and TMC2100 modules, according to their own needs. Besides, it employs the high performance USB serial chip FT232RL, which enables users to manipulate the control board via USB cable. Its output voltage is 12V.

LCD 2004 display is a basic 20 character by 4 line dot matrix controller module designed for different 3D printer motherboard. The product contains 20 Character x 4 Line LCD display, a rotary encoder and 30cm connection cables. There is a SD Card slot on the back of the LCD Module, connecting it with the controller board of 3D Printer. Just insert your SD card into the SD slot, you can print 3D models without PC.
