Buy a powerful digital regulator - MVM-AVIA ESC 4in1!

This is a professional 4-in-1 speed controller MVM-AVIA ESC for FPV quadcopters. The ESC4x1 v1.1 model is built on a high-performance AT32F421 microcontroller. Each channel is equipped with an independent 120 MHz processor. The device provides lightning-fast response and exceptional control accuracy.

• Four independent channels based on AT32F421 with a frequency of 120 MHz.

• Rated current 65 amperes per motor channel.

• Wide power range from 3S to 8S lithium polymer batteries.

• Modern AM32 firmware with support for digital protocols.

• Ultra-compact dimensions for easy integration into the frame.

Digital precision and software

The heart of the regulator is the AT32F421 microcontroller. This is a 32-bit processor with a Cortex-M4 core. The 120 MHz clock speed ensures instant signal processing. The device runs AM32 open firmware. This platform is famous for its stability and wide customization options.

The regulator supports advanced digital protocols DShot 300 and DShot 600. It is also compatible with the classic PWM signal. DShot ensures data transmission without errors or interference. You get pure telemetry of engine speeds. The response to the movement of the sticks occurs with minimal delay.

Electrical parameters and compatibility

The rated operating current per channel is 65 amperes. This allows the use of powerful brushless motors. Supply voltage range from 12 to 32 volts DC. The regulator is compatible with batteries from 3S to 8S in series. The versatility of the power supply is suitable for different classes of drones.

Connection to the flight controller is via a JST SH 1.0 mm connector. The contact group is designed for 8 conductors. Compact dimensions of 57x50x8 mm simplify placement in the frame. The device is easily integrated into cramped assembly conditions.

This is a solution for racing and freestyle drones. The regulator is ideal for powerful 5-7 inch copters. It provides a margin of safety during aggressive piloting. High PWM frequency guarantees smooth running of the motors.
