This is the latest version of the SpeedyBee F405 drone flight controller & stack - For the flight controller the V4 edition brings an updated the Gyro, it is now using the ICM-42688P. The BECs have also been uprated from 2A to 3A allowing for use of more power hungry HD systems. Other tweaks include native supports for DShot on all 8 motor outputs allowing for full DShot support in iNav. The most significant update is to the 4in1 ESC which brings more performance and improved reliability. It now boasts a rating of 55A and 70A burst, up from 50A and only a 55A burst. There's also the addition a metal heatsink and the selection of MOSFETS with lower internal resistance. A built-in TVS diode for surge protection reduces voltage spikes. Furthermore, the ESC is built with a thicker copper layer in its PCB, a 50% increase from previous version, providing additional reliability and heat dissipation capability.

The Speedy Bee F405 50A Stack V4 includes all the features a user would expect from a modern flight controller and ESC stack, but at an incredible price. The flight controller features the STM32F405 MCU, onboard 4-level battery life indicator, Micro-SD card slot for Blackbox logging, connections for LED strip (available here), DJI plug for digital quads, and built-in Bluetooth for wireless configuration through the SpeedyBee App. Paired with the SpeedyBee BLS 55A 4-in-1 ESC, delivering up to 55A continuous current, these components ensure a powerful and reliable drone setup for your aerial adventures.
