Sabvoton SM4830L
Budget Sabvoton SM-series 36-48V / 30A DC motor controller for e-scooters and light e-bikes. Lookup-table sine-wave drive (NOT true FOC, unlike the SVMC/ML/MZ lines) with selectable square-wave and sensorless (no-hall) modes. Pairs with UART No.2 displays (SW900/S866/M8).
In brief: 24–48V controller. 30A continuous. Sinewave, dual mode, self-learning support. From $24.
