{"product_id":"1pcs-ramps1-4-rrd-fan-adapter-new-hot","title":"1Pcs Ramps1.4 RRD Fan Adapter New Hot","description":"\u003cp\u003eITEM NAME:1Pcs Ramps1.4 RRD Fan Adapter New Hot Descriptio n Description: If you build or upgrade your printer with\/to DUAL-EXTRUSION (2 extruder) including a heated bed all the output ports (D8,D9,D10) will be used. In this case there is not option to connect a firmware controlled FAN to RAMPS board directly. However in Sprinter\/Marlin firmware there is an option already (Marlin: BOARD=34) which redirects the FAN to RAMPS output D4. But this solution needs a \"buffer\/driver\"in order to work. The RRD-FAN-EXTENDER is exactly what you need in this case. It is a plug and play 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 controllabe 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 dimmable LED light to your machine). Specifications: Features: max 20V 2 (PWM controllable) channels (D6\/D11) max 0.5A per channel (enough for a really big fan) flexible output voltage (you can connect the RRD-FAN-EXTENDER to 12V,5V,... in order to support the output voltage you need) each channel has a fly back diode easy setup (plug and play) already supported by Marlin firmware (choose \"#define MOTHERBOARD 34\") easy to adapapt to other firmware (e.g. Sprinter: just change \"#define FAN_PIN 6\" in \"pins.h\") TEST Test the Editing Reprap Ramps1.4 RRD Fan Extender Hardware required: -Ramps 1.4 -Mega2560 1.Upload Test for Editing Reprap Ramps1.4 RRD Fan Extender to your Mega. digitalWrite(11, LOW); digitalWrite(6, HIGH); delay(5000); } 2.Connecting 3.
