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.
- 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
- 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)
- USB
- UART (3.3V)
- Step/Dir/Enable (PoStep25-32 Compatible)
- BOM can be created using KiBoM
- There exists a modified version of the Firmware for this project: ElektronikNode/Mechaduino-Firmware
