The Tarot TL3304 Power Module is a high-power S-UBEC buck regulator designed for professional multirotors, large UAV platforms, and demanding FPV or mapping setups. Supporting wide-range DC input up to 80 V and delivering up to 120 W of regulated output, it provides a stable power hub for onboard electronics, payloads, and flight controllers.
Built around a CNC-machined 6061-T6 aluminium housing with integrated active cooling, the TL3304 combines excellent thermal performance with overload protection and precision voltage sensing. Multiple 12 V and 5 V outputs allow simultaneous powering of accessories such as cameras, transmitters, gimbals, and avionics, while the Vout interface enables voltage telemetry integration with mainstream flight controllers.
When paired with the optional Hall-effect current sensor module, the system also supports high-current measurement up to 200 A, making it ideal for monitoring power consumption on larger electric aircraft and heavy-lift multirotors.
With integrated XT30 connectors, clean wiring exits, and a compact mounting footprint, the TL3304 offers a tidy, robust power-distribution solution for high-end builds.
