25.5x25.5mm HGLRC SPECTER 15A ELRS AIO Flight Controller with 15A 4in1 ESC UARTS R1 ExpressLRS 2.4G RX for DIY 7585mm Whoop 3 Inch Toothpick RC FPV Racing Drone Precise details: Introduction: This is an F411 15A 24S ELRS AIO integrated brushless flight controller that integrates a UARTS serial port ExpressLRS 2.4G receiver. The integrated UARTS serial port receiver will be more stable than the SPI receiver in terms of performance/signal. It solves the problem of SIP receivers having few functions, cumbersome operation, and close signal distance. The integrated serial port ELRS receiver also solves the problem of no place to place the receiver during daily setup. The board has a reserved IPEX receiver seat and a Tshaped antenna, which can easily surround the harsh indoor environment flight. The ELRS receiver has the characteristics of high sensitivity, high refresh rate and low latency, and is loved by many FPV enthusiasts. This AIO flight controller can support up to 24S batteries, and is also compatible with 75mm/85mm whoop/3inch lightweight on the market. Toothpick /etc. frame. Selling point: * Supports input voltage up to 24s. * Newly upgraded and expanded UARTS port * The flight control uses F411 main control with MPU6000 gyroscope to make flight control feel smoother * The flight controller reserves a direct plugin motor base and an extra large motor pad, which can be used selectively * Builtin independent serial port ELRS receiver can reduce installation space and is very suitable for indoor /toothpick frame * Bluejay firmware is flashed by default to improve flight efficiency and is the best choice for flying drone Specification: Brand: HGLRC Model: SPECTER 15A AIO Item Name: F4 Flight Controller AIO 15A 4in1 ESC andUARTS R1 ExpressLRS 2.4G Receiver MCU: STM32F411 MPU: MPU6000 BEC: 5V2A Black box: 8MB OSD: support LED: support Buzzer: support UARTS: UARTS3 Builtin receiver: UARTS R1 ExpressLRS 2.4G Builtin receiver frequency: 2.4GHZ Continuous current: 15A Peak current: 18A (10s) ESC protocol: Dshot300, Dshot600, Oneshot, Multishot Flight control firmware: ZEUSF4EVO ESC firmware: QH50 (Bluejay) Input voltage: 24S 7.4V14.8v (Lipo) Size: 42.5x42.5mm Mounting hole: 25.5X25.5mm.M2 Weight: 6.9g Package Included: 1x SPECTER 15A AIO Board 1x 35V 220UF solid capacitor 1x XT30UM 18AWG 70mm male power cord 1x MX1.253P 30AWG 75mm camera cable 4x M2*6.6 Shockabsorbing column 1x HGLRC 2.4G Tshaped antenna
