A multi-channel ToolkitRC ST8 servo tester: 8 channels, up to 100 W, PWM/PPM/SBUS generation and measurement of current, voltage and angle.
The device connects up to 8 servos at once and powers them from a 7–28 V source with a total power of up to 100 W. The screen shows current, voltage, speed, rotation angle and pulse width, so gear binding or an internal short can be found before installing on board.
PWM (50–400 Hz), PPM (8 channels) and SBUS (16 channels) signals are supported, and the unit can both generate and measure them. Protection against overcurrent and reverse polarity is provided. It is powered via XT60, measures 99×68×26 mm and weighs 140 g.
Key Advantages
- 8 channels, up to 100 W
- Measures current, voltage, speed and angle
- PWM, PPM and SBUS
- Overload and reverse polarity protection
- XT60 power, weight 140 g
