Product overview
The YAHREE E2+ Drone Flight Controller provides onboard processing, sensing and external connections for UAV integration. Its hardware centers on an STM32H753 processor, identified more specifically as the STM32H753IIK6 running at up to 480 MHz. The controller measures 96 × 54 × 32.5 mm and weighs 144 g, defining its physical allocation within an aircraft. Compatibility with APM and PX4 gives integrators open-source software options, while expansion support includes devices intended to counter interference.
The onboard sensor configuration lists ICM42688-P, ICM-20649 and BMI088 accelerometer/gyroscope devices, BMM150 and RM3100 magnetometers, and two ICP-20100 barometers. External integration uses four UART interfaces, one RS422 interface, two CAN interfaces, four I²C interfaces and one Ethernet port. PWM outputs are specified as 8 + 6. A Type-C interface, TF card slot, SBUS input and SBUS output provide additional connection and storage interfaces. Full CAN bus support also forms part of the controller’s device integration capability.
Electrical integration requires an operating supply of 5 ± 0.25 V. Maximum power consumption is ≤ 5 W including peripheral devices, and the operating temperature range is -40°C to +70°C. Three power interfaces comprise one UAVCAN power connection, one I²C power connection and one ADC power connection. The I/O port specification is 5–8.4 V, 1 A, with external power required. When paired with a mobile ground station, the controller supports tasks across multiple scenarios.
