Revision to Hardware Overview

Tony

The Duet Wifi and Duet Ethernet both use the same base controller board. the difference is only in the communications module. This base controller board has gone through a number of minor revisions. The version number is marked on the silkscreen on the board, to the left of the large processor chip.

ChangedCompared to a Resettable VSSA. Now ifv1.02 it had the thermistor inputs are connected to VIN the VSSA fuse should reset rahter than needing to be replacedfollowing changes:
 
Added capacitors on stepper driver* The Fan MOSFETS now have a miniblade fuse in the VIN supply (not 5V supply).
* Each of the TMC2660s Stall Gauard
outputs is ORd together and fed to reduce EMIthe MCU. This allos for quicker reaction to SG signals.
* Minor routing changes

Added flyback diodes to the PWM fan outputs to protect against non brushless DC fans/pumps.Source files: https://github.com/T3P3/Duet/tree/master/Duet2/Duet2v1.03

Compared to v1.0 it had the following changes:
 
Minor* Minor routing changes
* The filter capacitors for the ADC inputs are connected to main ground, to better protect the MCU if the VSSA fuse blows
