KiCAD Projects: 619-J_Stepper (drive a stepper motor in closed loop mode)

23 Aug, 2022

KiCAD Projects: 619-J_Stepper

619-J_Stepper is an open source micro-controller board used to drive a stepper motor in closed loop mode. The board is generally used on 3D printer steppers or CNC steppers to prevent losing steps. The project is inspired by Tropical labs: Mechaduino board.

KiCAD Projects: 619-J_Stepper

Here are the features of the 619-J_Stepper:

STM32F103C8T6 ARM 32-bit Cortex™-M3 is the CPU of the board. Higher frequency, higher speed, and cost-effectiveness.
Magnetic encoder to Allegro's A1333LLETR-T Contactless 0° to 360° angle sensor IC,12bit
USB programming and serial communication (serial version)
High-speed printing without losing steps.
Ported the compilation platform from Arduino to PlatformIO - Convenient for STM32 MCU compilation
This project supports building and upload by platform, you can use Atom or Code editor (need to install platformio) to build it or upload the firmware.
Closed loop motor feedback.

The size fits perfectly NEMA17 Motor. The Main component for this 4-layer PCB was STM32F103, A4950T Full bridge motor driver, and A1333 as an angle Sensor.
