HighPower-Mechaduino

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! See v0.1_BUILD_LOG.md for some problems found while building the first prototype.

A big thanks to the Shuttleworth Foundation 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)

various informations

• BOM can be created using KiBoM
• There exists a modified version of the Firmware for this project: ElektronikNode/Mechaduino-Firmware
