ITEM NAME:RC Flight Controller Accessory Great Gifts for Pixhawk Flight Controller Lovers Description: PPM Encoder PWM to PPM Encoder for 2.4.8 PX4. PPM encoder is the role of the receiver output of multiple channel PWM signal encoded into PPM composite signal output, single-wire connection to support the control. In order to save port resources or layout constraints, Many fly control only allow to connect PPM signal, which requires PPM encoder. Some of the receiver products on the market can directly output PPM signals, is the same meaning, such as Graupner. PPM signals can also be used for direct connection to simulator dogs for wireless simulation training. Please note: PPM signal and S.BUS., XBUS similar, are single-line transmission of all channel signals, but several different coding methods, and can not be compatible with each other. Specification: Matreial: Plastic+Metal Size: Approx.28x19x5mm/1.10x0.75x0.20inch Package Includes: 1 Piece PPM Encoder 1 Piece JR 10 Pin input cable 1 Piece JR 4 Pin output cable 1 Piece Heat Shrinkable Tube Note: Please allow 1-3mm measuring deviation due to manual measurement. This PPM encoder hardware prototype comes from the PPZ PPM encoder, the default firmware for the development of 3DR, if you want to modify the function, please prepare your own ISP type programmer. The default power supply: PPM encoder by the control power supply, while the receiver can also be.1 Piece JR 10 Pin input cable. We do not provide any technical support. PPM signals can also be used for direct connection to simulator dogs for wireless simulation training. PPM Encoder PWM to PPM Encoder for 2.4.8 PX4.
