Product overview
The HAKRC 12S 42123 100A Stack combines a flight controller with a 4-in-1 ESC for UAV control and motor power management. Its stacked architecture uses an eight-layer, 4OZ thickened copper-core power board, 80V MOSFETs, Murata capacitors and industrial-grade DC-DC chips. The controller incorporates an STM32H743VIT6 processor, ICM42688 dual gyroscope, SPA06-003 barometer and AT7456E OSD. Eight serial ports, MicroSD storage support and ten motor signal outputs provide connections for flight-system integration, alongside 5V/3.5A and 12V/3A BEC outputs.
Integration options include dual video transmission, dual cameras, direct DJI Sky Port connection, external adjustable LEDs and remotely controlled LED-strip switches. Video power also has soft control. Firmware compatibility covers Betaflight, Ardupilot, INAV and PX4, with HAKRC H743 specified for the controller. The ESC accepts 6S-12S LiPo input and supports PWM through Dshot600 protocols. Its specified dimensions are 88*86mm and net weight is 117g. The 100A continuous-current figure carries a closed-incubator test qualification lasting about one minute; peak current is 110A.
