SBUS&PPM and PWM signal change:Short press the ID SET switch two times within 1 second, the signal is changed from normal PWMto SBUS&PPM. The red LED indicates the normal PWM and blue/purple indicates SBUS&PPM.Product feature:1. DSSS&FHSS act perfect on anti interference, especially on 433 and graph transmission.2. Output SBUS, PPM and PWM signals simultaneously.3. Top speed response, 3ms for all channels parallel.4. Top precision 4096, 0.25us every bit insure every servo stable.5. Sub miniature size, totally weights 3.4 grams, never burden to your drones, best choice forlight drones.6. All channels response parallel, totally 3ms.7. Specially used for light drones, compatible with all flight controllers such as DJI NAZA, ZEROTECH, PIX, APM, MINI APM, NAZE32, and CC3D etc.8. One single cable connect with the flight controller, easy setting.Specification:1. Channels: Red LED indicator is for PWM mode. Blue LED for SBUS&PPM, can be extended to 10channels.2. Power input: MAX 6V3. Control distance: 600 meters air, or even farther beyond your sight4. Current consumption: 38-45mA (5V)5. Size: L×W=25×15mm6. Weight: 3.4 grams7. Precision: 4096Installment of receiver antenna:1. The antenna must be kept as straight as possible. Otherwise it will reduce the effective range.2. Large model aircraft may of some metal part interfering signal; in this case the antennasshould be placed at both sides of the model. Then the best RF signal condition is obtained at anyflying attitude.3. The antennas must be kept away from conductive materials, such as metal and carbon by at
