Get ready to run your large scale with LocoFi! Do you need more than 1.5A to run your loco?
 
Now you can with LocoFi. By exposing two wires, you can interface it with any third party H-bridge that accepts "direction" and "pwm" as inputs. H-bridge, simply put will amplify your output current and yet controlled by LocoFi.
 
We are simplifying the process. Now you can order LocoFi™ 3 (DULLHB) with this customization right from this page. For more details about LocoFi™ for Large Scales (DC and AC power), please visit https://www.wifimodelrailroad.com/forum/locofi-tm-general/locofi-tm-for-large-scales-dc-and-ac-power.
 
The three wires needed for an external H-bridge will come grouped together. Please note the following color codes:
WHITE - DIR (not to be confused with the front light output +ive which is a separate wire)
YELLOW - PWM (not to be confused with the rear light output +ive which is a separate wire)
BLUE - GND
 
- External H-bridge module is not included in the kit.
- A larger speaker may be required for louder audio. A 4 Ohms 3W speaker with high sensitivity is recommended.
- Existing light outputs may be amplified and used to drive brighter higher wattage LEDs. Schematic provided on the webpage above.
