KiCad based Mechaduino derivative which drives up to 10A.
This is the original Meachaduino Project: https://hackaday.io/project/11224-mechaduino
Warning This Board is currently under development. Simply fabricating it doesn't mean it would work!
A big thanks to the Shuttleworth Foundation for supporting the development of this Project.
- ESD protection (especially USB)
- (flyback diodes)
- stronger drivers
- better silkscreen
- correct use of blocking capacitors
- fuse (for protection against polarity reversal and shorts)
- input voltage measurement
- supply of the microcontroller via the motor voltage supply
- electrically isolated input for step & dir
- add an additional external storage for calibration and configuration data (if we cannot store it on the arduino persistent and writable)
- graphical gui
- more controll options (force, velocity, position, acceleration, torque)
- zenner diodes (overvoltage protection when turning the motor)
- Temperature sensor
- Input Voltage-range of about 12V-50V
- N-Mosfet Driver which is capable of about 10A
- board in the size of NEMA 23 (56x56xmm) or NEMA 24 (60x60mm)
