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

ADC-GPIOS-SD-USB).
