Description:<br> brand new and high quality<br> The PPM Encoder plugs into the PWM servo output ports of any R/C receiver and encodes them into a PPM pulse suitable for many autopilots (e.g. Pixhawk). Modifications to the R/C receiver are not necessary.<br> The whole project is based around the ATMEL ATMEGA328p AVR processor and all timing is done within interrupts so accuracy and stability is optimized.<br> The design of the PPM Encoder is based on the Paperazzi PPM Encoder.<br> <br> Important tips: The firmware comes pre-configured to read 8 Channels. In for case you would like to change the settings of the PPM encoder to invert the PPM signal and change the fail safe pre-defined values you will need an AVR ISP programmer in order to reprogram it.<br> <br> The jumper on the board no soldering default. In this for case the board powered by FC<br> <br> Specifications:<br> Dimension: 28 x 19 x 5mm/1.1'' x 0.74'' x 0.2''(approx)<br> Color:as picture shown<br> Quantity: 1 set<br> <br> Note:<br> No retail package.<br> Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid.<br> Due to the difference between different monitors, the picture may not reflect the actual color of the item.
