Product overview
The GEPRC SPAN F405 HD 32bit 50A BEC F405 Flight Controller Stack combines a GEP-F405-HD controller with a GEPRC G50A four-in-one ESC for UAV flight control and motor control. Its tower arrangement uses a 36x36mm controller board with 4mm mounting holes and grommets reducing them to 3mm. The controller integrates an STM32F405 processor, MPU6000 SPI IMU, BMP280 barometer and 16Mb flash for black box recording. A Type-C USB interface, six UARTs, integrated LC filter and 5V and 9V BEC outputs provide connection and power provisions for integration.
The controller supports a direct connection to the DJI Digital FPV System, with a DJI cable included. Receiver protocol support covers Sbus, PPM, CRSF, DSMX and iBus. Both controller and ESC specify 3-6S LiPo input; the ESC lists 50A continuous current and 55A peak current under a 5S condition. It also provides current sensing and telemetry, with DSHOT1200/DSHOT600, PWM, Multishot and OneShot support. The supplied electronics package includes the controller, ESC, a 35V 470uf capacitor, mounting grommets, two screw lengths, an XT60 power cable and an ESC cable.
