Flight Controller RateFPV F4V4 40A Mini 3-6S F405 Stack

The RateFPV F4V4 40A Mini 3-6S F405 Stack is a powerful and high-performance "all-in-one" (AIO) board that combines a flight controller, a 40A electronic speed controller (ESC), a gyroscope, a barometer, and a wireless Bluetooth module. It is specially designed for modern agile FPV drones (3 to 5 inches), providing efficient control, high performance, and a fast, precise response. The main technical feature of this model is the use of an advanced STM32F405/435 processor with a 288MHz clock speed, which operates faster than traditional chips and ensures stable operation, high performance, precise control accuracy, as well as the ICM42688 gyroscope responsible for stability and position detection. The Rate F4V4 40A Mini is a comprehensive solution specifically designed for small FPV drones running on 3-6S batteries, with support for modern digital HD video systems.
