Product overview
The HAKRC 6-axis distribution board, identified as HAKRC 7155B-B13 12 S, provides power distribution and stepped-down supplies for onboard electronics. Its switching BEC uses an L5013C chip and provides two independently operating 5V outputs for receivers or flight controllers. Dual 12V outputs support equipment such as gimbals, video transmission systems, high-voltage servos, lights, payload release devices and smoke generators, provided the input is 4S~12S LiPo. The product is an electronic power distribution board for UAV integration.
The board measures 70 x 75 x10mm, weighs 26g and has mounting hole spacing of 30.5mm-30.5mm. Its input wiring configuration comprises a 15cm cable with an XT9 connector and one red-and-black pair of 8AWG silicone wires, alongside a 63V2000UF capacitor and a 10P-to-8P cable. It incorporates a current sensor, with an ammeter ratio of 50. The communication port designation is M1-M8, and the adapter connection notation is RX Adapter TX (4 ports).
The electrical ratings are 120A continuous current and 130A peak current, with an input range of 8.4~50.8 V from 2-12S LiPo batteries. BEC ratings are 5V 3.5A and 12V 3.5A; obtaining 12V requires 4S~12S LiPo input. Conversion efficiency is ≤95%, and static consumption is 1mA. Protection covers output short circuits and main-chip over-current and over-temperature conditions. Input polarity must be correct: red connects to battery positive and black to negative. Reversing these connections damages the board.
