Product overview
The CORVON 405v3 brings flight control, sensing and analog telemetry display together in a compact FPV controller. Its STM32F405RGT6 Cortex-M4 processor runs at 168 MHz with 1024 KB of flash and 192 KB of RAM. An ICM42688-P IMU works alongside an SPL06 barometer, while the integrated AT7456E OSD overlays telemetry on the analog video image. The board measures 36 × 36 × 8 mm, weighs 9 g and uses 30.5 × 30.5 mm mounting holes with M4 sizing. It has no compass.
Six UARTs, one I²C interface and ten PWM outputs provide connections for ESCs, GPS, receivers, video transmitters and DJI Air Units; PWM channels CH1–8 support DShot. The controller accepts a 2S–10S power battery and incorporates 5V 3A and 9V 3A BEC outputs. It also includes one SBUS interface, one current-sensing ADC, USB Type-C, one SWD debugging interface and a TF card slot for blackbox recording. INAV and Betaflight firmware are supported, and the operating ambient temperature range is 0°C – 45°C.
