The PPM Encoder plugs into the PWM servo output ports of any RC receiver and encodes them into a PPM pulse suitable for many autopilots eg Pixhawk Modifications to the RC receiver are not necessary The whole project is based around the ATMEL ATMEGA328p AVR processor and all timing is done within interrupts so accuracy and stability is optimized Important Note The firmware comes preconfigured to read 8 Channels In case you would like to change the settings of the PPM encoder to invert the PPM signal and change the fail safe predefined values you will need an AVR ISP programmer in order to reprogram it The I2C splitter expands the I2C port to allow up to four additional peripherals to connect to Pixhawk Use the 4 pin cable to connect the I2C splitter and add a compass module external LED digital airspeed sensor or other peripherals to your vehicle
