Happymodel CrazyF411 ELRS AIO 4in1 Flight Controller Built-in UART 2.4G ELRS Receiver 20A ESC for Crux35 Toothpick FPV R

Introduction The CrazyF411 ELRS flight controller comes with integrated UART 2 4GHz ExpressLRS receiver and 20A Blheli s ESC Bluejay firmware pre installed which could support 2 4s Bigger Mosfet could support high to 20A currents would be better for 2 4S toothpick drone or long range FPV drone And because the 2 4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity high packet rate and low latency this flight controller is the one that all Race Freestyle pilots needed The built in ELRS receiver is UART communication with MCU it s the same like Happymodel EP1 which you can update firmware by betaflight pass through or WIFI very simple The default firmware is ELRS V3 0 1 This flight controller would be used for Crux35 to instead ELRS X1 flight controller Specification Brand HappymodelModel CrazyF411 ELRSItem Name F4 Flight Controller AIO 20A ESC UART 2 4G ELRS ReceiverMount pattern 25 5 25 5 M2Size 32 28 9mmFlight ControllerMCU STM32F411CEU6 100MHZ 512K FLASH Sensor ICM42688P or BMI270 SPI Control Power supply 2 4S Lipo batteryBuilt in 20A Blheli s ESC eachBuilt in Betaflight OSD SPI Control Built in UART ExpressLRS 2 4GHz receiverBuilt in 5V 1 5A BECFlight controller firmware target CRAZYBEEF4DXOnboard 4in1 ESCMCU upgraded to EFM8BB21Power supply 2 4S LiPo LiPo HV 7v 17v Currents 20A continuous peak 25A 5 seconds Support BLHeliSuite programmableFactory firmware Bluejay 0 18 1Firmware target F H 40 48 v0 18 1Def
