HAKRC 7155 120A Drone ESC – 6S-12S LiPo, STM32G071, 140A Peak Current

The HAKRC 7155 120A ESC is a high-performance single ESC designed for high-power applications such as FPV drones, industrial UAVs, and RC airplanes. Built with an 8-layer 4oz thickened copper PCB and a double-pad design, it ensures exceptional current handling capacity and thermal dissipation.

This ESC features an STM32G071G8U6 MCU running at 64MHz, paired with SLM21867CA-DG drivers and NCEP016N80 high-current 80V MOSFETs, offering long lifespan and reliable power delivery. It supports a wide voltage range of 6S to 12S LiPo batteries and delivers 120A continuous and 140A peak current, making it ideal for demanding power systems.

The board is built using Murata capacitors from Japan for outstanding filtering performance and industrial-grade LDOs for high-temperature tolerance. A customizable programmable LED system adds visual diagnostics or style.
