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 4 stepper motors, namely, XYZ axial motor and an extruder. 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.
Geeetech full-color touch screen is a display of 3.2 inch, designed to be intuitive, responsive and user-friendly. With an SD or TF card, you can control your 3D printer via the touch screen, untethered to your computer. Totally streamline your printing process and enhance using experience.
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.

I have A30M with Smartto MB. I want to replace with this GTM32 board. Is okay ?? If okay, can current A30M LCD work with this GTM32 board?? XieXie.
Hello, it cannot be replaced.
Hello, does it fit the 12v- Version of A30?
hello, if your 12V A30 is also with this GTM32 MINI board , then it can fit
Can this be used on the A10T?
hello, no , A10T board is not listed on our store . you can order this board , but leave a comment for your order , need A10T control board instead. i will change order for you when i process orders .
Hi here. Is this MB the same that is installed in E180 printer? I've got in in Feb 2017. Now I'm thinking about heat bed on it. But I can't see black socket (hotbed PWM and temperature) on my MB....
Will this work on a A20M?
you need change the firmware to support the touch screen and also need change the wires
will this work for an A10?
It need you to do upgrade by yourself otherwise, it can not. A10 now use GT2560V3 board rather than GTM32
Is it compatible with Marlin?
you need reinstall the firmware, thanks
Se puede instalar en la a10m, alguna otra tft tactil para arduino?
hello, this can not use on A10M, please send mails to victory.lei@geeetech.cn, he will arrange it offline, thanks ,thanks
I Can be installed it in an A10M?
hello, this can not use on A10M, please send mails to victory.lei@geeetech.cn, he will arrange it offline, thanks ,thanks
Hi, Will this board take the TMC2130 ? Which drivers comes with the A30 3D printer that I just ordered from Gearbest ? Thanks.
A4988 with A30. tmc2130 we do not test it.
Thank you for your fast response. I will try TMC2130. I see here that TMC2130 is OK?
I meant TMC2100
it can use but you need change the stepper mottor direction, thanks
Rostock 301に使えますか？
hello, this can not use on Rostock 301, please send mails to victory.lei@geeetech.cn, thanks
What type of Firmware runs on this? ... the A30 does not use Marlin?
Hi Gary, yes, we do not use marlin, we use our own smartto open source firmware, we have share the firmware on github, please refer: https://github.com/Geeetech3D/Smartto/， thanks
can I buy only touch screen? What about construction element for 301 to fit the screen, is it available aswell? Regards Greg.
hello,this sell together with the board, please contact victory.lei@geeetech.cn buying the screen separately, thanks
Is this the board use in A30? If so, where can I find more detail for it? Thanks.
Hello Vincent, yes, this can use for A30,if you need more details,please contact victory.lei@geeetech.cn,thanks
THE Document link is not working.
hello vincent, Thanks your kind warning,i will update it,the doc is the same as the product info, so you can reference it by product info,thanks
