Features: Input SBUS signal and output PWM and PPM signals simultaneously. Input PWM signal and simultaneously output PPM and SBUS signals. Input PPM signal and output PWM and SBUS signals simultaneously. When any one or more channels of the 1-8 channel input PWM signals, the corresponding PPM channel outputs the PPM signal, and the SBUS channel outputs the SBUS signal. When the PPM channel inputs the PPM signal, it corresponds to the 1-8 channel output PWM signal, and the SBUS channel outputs the SBUS signal. When the SBUS channel inputs the SBUS signal, it corresponds to the 1-8 channel output PWM signal, and the PPM channel outputs the PPM signal. Specifications: Material:PCB Input voltage: 3.3-20V Current: 15mA Dimensions: 21mm/0.82'' Channel: 8CH Package Includes: 1x Signal Conversion Module note: Please allow 1mm errors due to manual measurement.
