Features: This 4 in 1 module expansion board revolutionizes 1/14 remote control trucks with 4 programmable PH2.0 port, enabling simultaneous control of lights through intelligent constant voltages compatibility. With extreme temperature resilienced ( 30℃~80℃), plus foolproof quick release connectors and 90% faster installation than soldering solution. Ideal for truck enthusiasts upgrading Tamiya compatible 1/14 scale models, particularly builders requiring multiple light synchronization without voltages interferences or complex wiring. Perfectly for competitive racing environment where rapid light module reconfiguration, shock resistant cabling, and double circuit protections criticals during fast speed maneuvers. Embeddedly voltages stabilizing automatically compensates for signal fluctuations while redundant circuit isolation maintains 75% functionality during overloads essential for maintaining competition grade light consistency.
