Happymodel CrazyF411 ELRS AIO 4in1 BMI270/ICM42688-P Flight controller

Are you in Australia and looking to buy a top - notch flight controller? The Happymodel CrazyF411 ELRS 2.4GHz flight controller is your perfect choice. It comes with an integrated 2.4GHz ExpressLRS receiver and a 20A BLHeli_S ESC with pre - installed Bluejay firmware, supporting 2 - 4S batteries. The bigger Mosfet handling up to 20A currents is great for 2 - 4S toothpick drones or long - range FPV drones. The 2.4GHz ExpressLRS receiver, equipped with the high - sensitivity SX1280 radio frequency chip, offers high packet rate and low latency, making it a must - have for race and freestyle pilots. The built - in ELRS receiver uses UART communication with the MCU, just like the Happymodel EP1. You can easily update its firmware via Betaflight pass - through or WIFI. The default firmware is ELRS V3.0.1. This flight controller can replace the ELRS X1 in the Crux35. Specifications: FC has an STM32F411CEU6 MCU, ICM42688P or BMI270 sensor, 25.5×25.5 M2 mount pattern, 32*28*9mm size, 2 - 4S power supply, built - in 20A Blheli_s ESC, Betaflight OSD, UART ExpressLRS 2.4GHz receiver, and 5V 1.5A BEC. The onboard 4in1 ESC has an upgraded MCU, supports 2 - 4S LiPo/LiPo HV, 20A continuous peak 25A (5 seconds), and is BLHeliSuite programmable. The onboard UART ExpressLRS 2.4GHz Receiver offers multiple packet rate options, 2.4GHz RF frequency, and CRSF protocol. Onboard voltage and amperage meters have specific scale settings. It includes 1 x Happymodel CrazyF411 20A F4 ELRS 2.4GHz Whoop AIO Flight Controller.

Using the Happymodel CrazyF411 ELRS flight controller is easy. First, connect it to your drone following the mounting pattern of 25.5×25.5 M2. Make sure to use a 2 - 4S Lipo battery for power supply. When it comes to the receiver, you can choose different packet rates according to your needs. If you want to update the firmware, you can do it through Betaflight pass - through or WIFI, just like with the Happymodel EP1. For the ESC, you can program it using BLHeliSuite. Some things to note: Don't exceed the current limits. The ESC can handle 20A continuously and 25A for 5 seconds. When using the voltage and amperage meters, keep the scale settings in mind. For maintenance, regularly check the connections to make sure they are secure. If you notice any damage to the controller or its components, replace them as soon as possible.
