Aocoda F405 V4 is an "all-round" racing flight controller, with high integration, strong scalability and outstanding cost performance as its core advantages. Compared with the V3 version, its upgrade points include dual gyroscopes, more UART interfaces, and a higher power BEC. It is suitable for users who pursue comprehensive functions and have a limited budget. For most racing and entertainment scenarios, the F405 V4 is sufficient.
Core highlights
Upgraded F4 main control chip
1. It adopts the STM32F405RGT6 main control chip with a main frequency of 168 MHZ, and is equipped with a hardware floating-point operation unit (FPU), supporting high refresh rate PID control (up to 16kHz), ensuring low-latency response in racing scenarios.
2. The processing efficiency of the optimized algorithm is enhanced, the dynamic filtering performance is stronger, and the flight stability is significantly improved.
Full-function integrated design
1. On-board OSD chip: Supports custom image transmission information overlay (voltage, flight mode, timer, etc.), no external module required, simplifying wiring.
2. High-precision barometer (Baro) : It realizes fixed-altitude flight and altitude locking functions, suitable for flower flight and light aerial photography needs.
3. Built-in black box (BlackBox) : On-board 8MB SPI Flash storage, automatically records flight data, facilitating participation in fault analysis in the later stage.
Professional-level power management
1. Supports 2S-6S lithium battery input, integrates an efficient voltage stabilizing circuit to reduce voltage fluctuation interference.
2. It provides 9V/12V BEC output (with a maximum current of 2A), directly powering the video transmission, camera and receiver, reducing the need for external BEC.
Optimize the hardware configuration for racing
1. Dual gyroscope design: Equipped with the ICM-42688-P gyroscope, it supports a sampling rate of up to 32kHz, reducing noise interference during high-speed maneuverability.
2. Low-latency signal transmission: Supports DShot1200 electrical adjustment agreement and bidirectional DShot, enhancing motor response speed and RPM filtering effect.
Scalability and compatibility
1. 7 UART serial ports: Compatible with GPS, data transmission, LED light strips, optical flow modules and other peripheral devices, meeting the requirements of complex function expansion.
2. Native support Betaflight INAV/EmuFlight firmware, templates preset racing optimization parameters, novice quick learning.
Durable design
Four-layer PCB board: Enhances anti-interference capability and reduces high-frequency signal loss.
Competitive advantage
High cost-performance all-round flight control
1. Among similar F4 flight controllers (such as Matek F405 and TBS F4), the three major functions of OSD, Baro and BlackBox are integrated at a lower price, eliminating the cost for users to purchase additional modules.
2. The performance is comparable to that of the mid-range F7 flight controller, but the price is more affordable, making it suitable for advanced players with limited budgets.
In-depth optimization for racing
1. Gyroscope redundancy design: The dual ICM-42688-P gyroscopes support data fusion, reducing the risk of failure of a single sensor and enhancing flight reliability.
2. Ultra-low latency circuit layout: Optimize the signal path, reduce PID cycle delay, and be suitable for high-frequency maneuvers (such as sharp turns and rapid rollovers).
