Product overview
The EZI-HOBBY H743 Flight Controller FPV Stack 120A ESC Drone Flight Stack brings together flight control, power distribution and four individual ESCs for FPV drones. Suitable applications include 17-inch FPV drones using YBL series 5220, 5225, 5230, 5320, 5325 or 5330 motors. Supplied equipment comprises one YY 12S H743 flight controller, one YY 12S-7155 power distribution board and four ESCs. Each ESC measures 55 × 32 mm, weighs 23 g and uses high current-carrying MOSFETs.
The 40 × 40 mm, 11.3 g flight controller combines an STM32H743VIT6 processor, ICM42688 dual gyroscope, SPA06-003 barometer and AT7456E OSD. It provides eight serial ports, 16M black box storage and BEC outputs of 5V/3.5A and 12V/3A. Each ESC uses an AT32F421K8U7 control chip operating at up to 120 MHz and supports PWM, Oneshot125, Oneshot42, Multishot and Dshot150/300/600 signals. ESC continuous current is 120 A for 7 seconds, with a maximum of 140 A for 3 seconds.
