Betaflight Current Sensor Calibrator – Scale & Offset

Automatically calculate new sensor parameters from your measurements. Two modes: BF→mV (from I_BF & I_real) or Direct mV (from V_mV & I_real).

1) Current Betaflight Parameters

Model: I = (10/scale)·V + offset/1000, with V in mV and I in A.

2A) Paired Measurements: IBF & Ireal

#I_BF (A)I_real (A)
Use this mode if you recorded the Betaflight display (A) while measuring with a multimeter.

2B) Measurements: VmV & Ireal (direct mV)

#V_mV (mV)I_real (A)
If you already have the ADC voltage in mV (or from a logger), use this mode directly.

3) Results

New scale: —
New offset: — mA
Fit quality R²: —

Tip: If, with quad idle, Betaflight does not show 0 A, adjust the offset slightly (±10–50 mA).
