Product overview
The Long UAV FC&ESC Stack F405 V3 BLS 65A provides flight control and electronic speed control hardware for integration into a UAV. Its separate flight controller and ESC boards measure 39.8 × 38.7 × 7.8 mm and 45.5 × 41.5 × 6.4 mm, respectively, with matching 30.5 × 30.5 mm mounting patterns and φ4 mm holes. The controller combines an STM32F405RGT6 MCU, ICM42688P gyro, SPL06 barometer and 16 MB storage. Six UART ports, SBUS on UART3 and a six-pin DJI Air Unit connector provide integration interfaces.
Electrical integration must accommodate the boards’ different input ranges: 3–8S for the flight controller and 3–6S for the ESC. The controller provides 5V / 3A and 12V / 2.5A BEC outputs, while the ESC specifies 65 A continuous and 80 A maximum current. BetaFlight is the default controller firmware, with iNAV and ArduPilot also supported. The supplied accessories comprise four M3 nylon nuts, eight M3 red shock absorbing balls, one 50V 680µF capacitor, an XT60 power cord and cables for 8P, CRSF receiver, adapter and camera connections.
