JHEMCU F4 NOXE V3 STM32F411 Flight Controller 20x20, 5V/2.5A & 10V/2A BEC, OSD, Baro, 16MB

Overview

The JHEMCU F411 NOXE V3 is a flight controller designed around an STM32F411 MCU with onboard OSD, barometer, dual BEC outputs (5V and 10V), and 16MB blackbox memory. It uses a 20 x 20 mm mounting pattern (3 mm holes) and supports common RC receiver protocols and ESC signal types for compact FPV builds.

Details

A compact 20×20 flight controller built around the STM32F411 MCU for space-conscious FPV stacks.

Onboard features include integrated OSD support and multiple UART options for common receiver protocols.

The open pad layout makes it easier to route power, ESC signals, and peripherals in tight builds.

Lightweight design helps keep total build weight down at about 4.3 g.

Included hardware covers basic installation: flight controller, two cable harnesses, and four soft mounting grommets.

Key specs at a glance: 2S–6S input, 16MB blackbox, ICM-42688-P gyro, plus 5V and 10V BEC outputs.
