Description
The STEVAL-3DP001V1 is a complete and
integrated solution for driving all 3D printers on
the market, including Delta models requiring
more complex computation. The solution is ideal
for both beginners and experienced users. It is
autonomous and can be used with a software
interface or with custom firmware thanks to the
embedded STM32 microcontroller based on the
ARM 32-bit Cortex M4 core. The STEVAL-
3DP001V1 is designed to drive 3D printers
providing several axes (6 motors), several
extruders (1 to 3), and multi-zone heating bed (1
to 3).
The STEVAL-3DP001V1 features integrated WiFi
connectivity, enabling the user to drive a 3D
printer using a smartphone or tablet. The solution
is also designed to work with 3D printer tools,
such as Pronterface. USB connectivity is
available through Virtual COM port, mini USB
OTG and Dongle USB A. Moreover, the board
includes a complete debug solution (STLINK-V2),
a tool that is appreciated by developers.
The STEVAL-3DP001V1 allows connection to
another board (e.g. Raspberry board or user
board), with a connector that provides drive
power (5 V - 3.3 V) and digital interface (SPI-I
2
C-
ADC-GPIOS-SD-USB).
