Features: On-board double LDO, sensoring independent power supply, more stable flight. 77PWM output, 3.5 serial port (SBUS can only count as half a serial port). Suitable for small and miniature fixed wing (such as f80, microed clawed, hand thrower, for Arwing Mini ). Not with analogs ammeter function (can be external I2C protocol ammeter). Support battery voltages output (SH1.02P interfaced) battery voltages at the same timing for the clear map transmission direct port power supply, the highest support 6s input. Can be directly inserted into the ELRS receiver, the ultimatedly reduction in size. Specifications: Main Control STM32F405RGT6 Support: ICM42605 Support: SPL06-001 3xUARTs 1xSBUS, 6xPWM, 1xI2C Current Meter: External I2C Current Meter Voltmeter: 2.5~30V, 1~6SLiPo Power input: 5V Size: about 27.9x20.3x11.2mm/1.1x0.8x0.44in Weighs only 2.8grams (5.3 grams without pin, after welding) Main control: STM32F405RGT6 168Mhz main frequency, 1MB Flash ICM42605, third-generation sensoring, optimized for UAV applications. TypeC interfaced directly into the flight control, stable connection Package Includes: 1PC Flight Controller note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
