SpeedyBee F405 V4 BLS Flight controller & 55A ESC Stack

The fourth version of the SpeedyBee stack includes an FC F405 and a BLHeli_S 55A ESC. The 30x30mm stack can support up to eight motors, is configured via Bluetooth, has a bult-in barometer as well as an ICM42688P gyro. The SpeedyBee F405 V4 stack is both complete and inexpensive, all with good performance. Always equipped with a Bluetooth controller allowing settings via the mobile application, the stack also has a TVS diode protecting the electronics. Integrated LEDs indicate the battery charge level and 2 3A BECs provide a 5V and 9V power supply.
