Duet 2 Wifi is an advanced 32 bit electronics for the control of 3D printers and other CNC machines. It has the same features as the Duet 2 Ethernet other than providing a WiFi connectivity rather than ethernet.
This is a daughterboard specifically designed for the Duet 2 Wifi, Duet 2 Ethernet and Duet 2 Maestro that allows two PT100 temperature sensors to be attached. These PT100 sensors can be either two or 4 wire, there are jumpers on the latest version of the board for easily switching between two and 4 wire mode.
