PandaCAN is an extruder control board that connect to main board with CAN interface, more resistant to signal noise,reduce a lot of wires for your 3D printer.
CAN(Controller Area Network) is a robust serial communication bus found mostly in automotive and industrial environments.
-
Resistant to noise, you will have less signal noise and wiring problem.
-
Reduce the wires from more than 19 to only 4.
19 = hotend cooling Fan: 2 + model cooling Fan: 2 + heater: 2 + temperature sensor: 2 + BLtouch: 5 + Extruder motor: 4+Runout sensor:2
-
High data rate 1Mbps.
