RAMPS1.4 RRD Fan Extender

Description

The RRD-FAN-EXTENDER is exactly what you need in this case. It is a plug and plays solution to mount the FAN for DUAL-EXTRUSION setups with RAMPS1.4. But instead of

adding only one additional output port, the RRD-FAN-EXTENDER is equipped with 2 PWM controllable channels(D6/D11). The second channel can be used for another fan

(e.g. to cool the stepper driver) or for adding light control (e.g. add a dimmable LED light to your machine).

Features:

1. Flexible output voltage (you can connect the RRD-FAN-EXTENDER to 12V,5V,… in order to support the output voltage you need)
2. Each channel has a flyback diode
3. Easy setup (plug and play)
4. Already supported by Marlin firmware (choose “#define MOTHERBOARD 34”)
5. Easy to adapapt to other firmware (e.g. Sprinter: just change “#define FAN_PIN 6” in “pins.h”)

Package Includes:

1 x RAMPS1.4 RRD Fan Extender
