BetaFPV Lite 1S

Multirotors → Tinywhoops → Whoop Flight Controllers → Brushless Whoop FC → BetaFPV Lite 1S

After the first brushless Silverware FC board Lite 2S, the Lite1S brushless flight controller is here.

The stock power cable connector of this FC is solid pins PH2.0 connector. If you want to try the new BT2.0 connector, you could get the BT2.0 connectors FREE and re-solder it.

Know more about the BT2.0 connector.

BUTTERWORTH FILTER

Original Silverware firmware has the bug that accelerometer based drift entering the fusion which manifests as a slower and slower yaw response. This is noticeable in level mode for almost all the Silverware based FC boards.

Now we have fixed it. Filter the accelerometer data first with low pass Butterworth filter and let it participating in flight.

Below is the gravity vector value GEstG[x] drift graph when no correct accelerometer data participates.

OSD MENU

Lite 1S Brushless FC is with build-in OSD which is convenient for changing settings. It supports PID tuning, motor spinning direction changing and channel mapping of AETR in default. The power and frequency of VTX can be switched directly. The operation of OSD Menu on Lite 1S Brushless FC is the same as Betaflight.
