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.

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

The first production version. comparedCompared to the prototype it had the following changes:
ESP_COMMS Header breaks out all the spare ESP pins.
Added test points for Step,Dir and CS for the onboard stepper drivers.
