★The design of the PPM Encoder is based on the Paperazzi PPM Encoder.
★The whole project is based around the ATMEL ATMEGA328p AVR processor and all timing is done within interrupts so accuracy and stability is optimized.
★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.
★Expands the i2c port to allow up to four additional peripherals to connect to pixhawk. Use the 4-wire cable to connect the i2c splitter and add a compass module, external led, digital airspeed sensor, or other peripherals to your vehicle.
★Important Note:The firmware comes pre-configured 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 pre-defined values you will need an AVR ISP programmer in order to reprogram it.
