Part 2 – Flight Controller
Wiring Diagram
**USB-C Module***
- Due to the size limitation, there’s no 5V output from the FC to the USB-C module, so you need to power the AIO with a battery before you connect the AIO flight controller to your computer with a USB-C cable.
App
- Get the SpeedyBee App
Search `SpeedyBee’ on Google Play or App Store. Or download the Android .apk file on our website: https://www.speedybee.com/download.
Connect the App
FC Firmware Update
BlackBox Analyzer
Part 3 – ESC
Connection with Motors & Power Cable
Note: In order to prevent the AIO from being burnt out instantaneous voltage spikes on powering up, it is strongly recommended to use the Low ESR capacitor in the package.
ESC Configuration
ESC Firmware Update
- You could flash both BLHeli_S and Blue Jay firmware for this ESC.
You need to pulg in the battery to the AIO and then connect a USB cable between the AIO and your PC. Then flash ESC firmware (BLHeli_S or Blue Jay) in the following online configurator: https://esc-configurator.com/
Note: ESC Type should be set as ‘J-H-40’.
