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. 

 

2. Features of GTM32

a. Adopting high-performance Cortex M3 core chip STM32F103, with its running frequency of up to 72MHz.

b. Using high-performance USN serial chip FT232RL, manufactured by FTDI, compatible with Windows, OS X, Linux etc. mainstream operation system.

c. The output voltage of GTM32 control board is 12V. It is characterized by dual power supply design, powering up the hotbed and other electronic components respectively. The current for hotbed is 9A and 7A for other parts.

d. The main circuit adopts in-line fuse, with overcurrent protection and reverse protection. The USB power supply interface has a restorable fuse, with its current at 500mA.

e. The control board features three interfaces for PWM fans.

f. Supporting up to 4 stepper motors, namely, XYZ axial motor and an extruder. The common stepper motor drivers are A4988 and TMC2100.

g. Dual temp sensor input: one for the extruder, the other for the hotbed. 100K thermistor is recommended.

h. The control board comes with expansion interfaces for LCD display and SD card, supporting stand-alone printing.

i. With a buzzer on board.
