CORVON 405v3
Flight Controller
Specification Sheet
01 / Product Overview

The CORVON 405v3 is a compact 36 × 36 mm FPV flight controller built on the STM32F405RGT6 Cortex-M4 MCU at 168 MHz with 1 MB flash. A high-accuracy ICM42688-P IMU pairs with an SPL06 barometer for stable altitude hold and reliable flight, while integrated AT7456E OSD overlays telemetry on the analog video feed. 6 UARTs, I²C, and 10 PWM outputs (CH1–8 DShot-capable) drive a complete FPV stack — ESC, GPS, receiver, VTX, and DJI air unit. Wide 2S–10S input feeds onboard 5V · 3A and 9V · 3A BEC rails, with an onboard TF card slot for blackbox logging. Runs INAV and Betaflight.
