Product overview
The EZI-HOBBY F4V3 FPV Stack combines an F4551 V3 flight controller with a 90A four-in-one BLHeli-32Bit ESC for FPV drone projects. Suitable applications include 13-inch FPV/UAV builds using YBL series 4214, 4315 or 3515 motors. The flight controller measures 36x36mm and weighs 8.5g, while the ESC measures 56*52mm and weighs 33g. Both boards use 30.5×30.5mm mounting hole spacing. The ESC supports 2-8S batteries, with a continuous current rating of 90A and a maximum of 110A for 10 seconds.
The flight controller pairs an STM32F405RGT6 processor with an ICM42688 gyroscope, 16M black box storage and an AT7456E OSD. Its connections include six serial ports and BEC outputs rated at 5V/4A and 12V/3A. Receiver support covers Frsky, Futaba, Flysky, TBS Crossfire, DSMX and DSM2. The ESC supports current sensing and accepts PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300 and Dshot600 drive signals. Its firmware version is BLHeliSuite16714902A_Beta.
