Board - SpeedyBee F4 AIO
Descriptions
This SpeedyBee F4 AIO board integrates the Bluetooth module, with SpeedyBee App, we can set the FC parameter via mobile device.It runs Betaflight, with Built-in LC-Filter for 5V and 9V, and no pinned-connectors – all direct solder for optimal durability on top side. It has the current sensor and ESC power output.
