Duet 2 Wifi with external antenna

by Duet3D


Duet 2 Wifi
controller board with external antenna for 3D-printers, based on a 32-Bit ARM processor and 5x TMC2660 stepper drivers. This electronic board provides 12V und 24V stepper, heat elements and 3.3V sensors. Duet Wifi can be connected via PC, tablet or smartphone on the same wireless network to the board web interface. The external antenna expands the reach of the wirless network and allows to encase the Duet 2 Wifi.

Various daughterboards enable the use of many sensors and up to 10 steppers.
