Introduction
GTM32 is a fully self-developed 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.
