HighPower-Mechaduino

KiCad based Mechaduino derivative which drives up to 10A.

This is the original Meachaduino Project: <![CDATA[]]>https://hackaday.io/project/11224-mechaduino<![CDATA[]]>

Warning: This Board is currently under development. Simply fabricating it doesn't mean it would work!
See <![CDATA[]]>v0.1_BUILD_LOG.md<![CDATA[]]> for some problems
found while building the first prototype.

A big thanks to the <![CDATA[]]>Shuttleworth Foundation<![CDATA[]]> for supporting the development of this Project.



Improvements


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
external storage for calibration and configuration data
Temperature sensor


Planned Electrical/Mechanical Ratings


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)


Interfaces


USB
UART (3.3V)
Step/Dir/Enable (PoStep25-32 Compatible)
