It expands the Pixhawk’s I2C port to connect up to four additional peripherals, enabling enhanced sensor integration without modifying your RC receiver. Pre-configured firmware supports 8 channels, with advanced customization available via AVR ISP programming. ## Description Product description Dimension(mm): 28 x 19 x 5 Weight(g): 9(include all wire) 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. T he jumper on the board no soldering default. In this case the board powered by FC PPM Encoder Features 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. The whole project is based around the ATMEL ATMEGA328p AVR processor and all timing is done within interrupts so accuracy and stability is optimized. Firmware is free and was created by John Arne and Olivier Adler. The design of the PPM Encoder is based on the Paperazzi PPM Encoder. Note that if the existence of the cable portion of red and black lines received the wrong location, please ignore, because it does not affect the use, but the color sequence is incorrect, you can swap your own if necessary. Pixhawk/APM flight control only one I2C interface, such as the need to connect more than one I2C peripheral, you can use the line board; Pixhawk - I2C points line board with five completely parallel vertical 1.25 4 a socket, convenient connection in the form of 1 drag 4 four I2C peripherals, for example, at the same time use the external compass and RGB modules.

Joe Review: struggled to use this for a rover. - Had enormous trouble getting this to work with brushed motors, mission planner, pretty much everything. Finally scrapped it and went with Radiolink crossflight. That was no trouble at all! ## Features - ★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).
