Revision to Hardware Overview


== Hardware limitations ==
* The DueX4 expansion board that was made to go with the Duet 0.6 and 0.8.5 is '''not''' compatible with the Duet WiFi. Use the [[Duex2 and Duex5 Features|DueX2 or DueX5]] instead.
* The maximum recommended power input voltage is 25V. This is a permanent limitation, because the TMC2660 drivers are rated at 30V when supplying power to motors.
* On the white pre-production boards in some wiring configurations, if you reset the Duet WiFi by pressing the Reset button when the motors are energised, then the stepper motors may move while the Reset button is held down. This is fixed in the production boards.
