M3 Shockproof Sponge Pad-4pcs.

Radiolink Has optimised its pixhawk flight controller PCB layout and height hold with the barometer sensor MS5611. It is a highly stable flight controller that comes from the radiolink. This controller provides more stable flight performance even at high speed. It integrated the newest 32-bit chip technology and high-end sensors, this is absolutely one of the best flight controllers for quadcopters.

Feature:

• Multi-sound buzzer interface support.
• Multiple flight modes, support for self-stability, height-set, hover, sports, freestyle, circling, following, return, guidance, automatic, and all-powerful.
• Abundant connectivity options for additional peripherals (GPS, I2C, SPI).
• 14 PWM / servo outputs (8 with failsafe and manual override, 6 auxiliary, high-power compatible).
• Providing a multi-sound buzzer interface.
• Multiple flight mode switches freely, Helicopter, Fixed-wing, Multi-rotor, Model Car.
• All interfaces are fully tested and accurately detected by an automatic detection system, avoiding bad interfaces leading to flight control installation unsuccessfully.
• Support DSM Spektrum receiver.
• Advanced 32-bit CortexM4 ARM high-performance processor, and 32-bit STM32STMF100 failsafe co-processor.
• Equipped with buzzer, 4G memory card, safety switch and power module.
