SpeedyBee F7 V3 50A stack

SpeedyBee released the third version of the SpeedyBee F7 50A stack. It has quite a number of changes and improvements. Some of the features are (almost) unique in the market. Lets take a short overview of them.

The gyro was changed from the end of the production MPU-6000 to the new trending Bosch BMI-270.

Blackbox chip size was increased from 16MB onboard data flash to enormous 500MB. It’s a half of Terabyte of log data! You could probably store a whole season Blackbox data on your SpeedyBee F7 V3 FC. That’s the biggest built in blackbox on a chip size in the market.

There is a battery voltage checker built in right on the FC board. 4 LED indicators show the battery charge state.

SpeedyBee F7 V3 also has 5 UARTS, I2C, BMP280 barometer, 8 motor outputs. The FC has 9V, 5V, 4.5V and 3.3V outputs to fit any needs.

You can use solder pads or plugs for connecting the peripherals.

SpeedyBee F7 V3 50A is a premium specs stack with wireless features.

BuzzerBZ+ and BZ- pad used for 5V Buzzer
BOOT ButtonSupported.
[A]. Press and hold BOOT button and power the FC on at the same time will force the FC to enter DFU mode, this is for firmware flashing when the FC gets bricked.
[B]. When the FC is powered on and in standby mode, the BOOT button can be used to controller the LED strips connected to LED1-LED4 connectors on the bottom side. By default, short-press the BOOT button to cycle the LED displaying mode. Long-press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. Under BF-LED mode, all the LED1-LED4 strips will be controlled by Betaflight firmware.
RSSI InputSupported. Named as RS on the front side.
SmartPortUse any TX pad of UART for the SmartPort feature.
