Powered by the ATMEGA328p processor, it ensures stable timing through interrupt-driven processing. Additionally, it expands the Pixhawk I2C port to connect up to four extra peripherals, enabling enhanced sensor integration without modifying your R/C receiver. Firmware customization is possible with an AVR ISP programmer, making it a versatile upgrade for professional drone pilots and hobbyists alike. ## Description Buy FPVDrone 8CH PPM Encoder & Pixhawk I2C Splitter Expand Module | For Pixhawk Flight Controller APM Flight Controller: Quadcopters & Multirotors - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Not a Good Product - I bought 6 of these and none of them worked! 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). 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #342,123 in Toys & Games ( See Top 100 in Toys & Games ) #1,319 in Hobby RC Quadcopters & Multirotors | | Customer Reviews | 4.1 out of 5 stars 33 Reviews | ## Images ![8CH PPM Encoder & Pixhawk I2C Splitter Expand Module - Image 1](https://m.media-amazon.com/images/I/719GnTtuJqL.jpg) ![8CH PPM Encoder & Pixhawk I2C Splitter Expand Module - Image 2](https://m.media-amazon.com/images/I/71fMlKxehrL.jpg) ![8CH PPM Encoder & Pixhawk I2C Splitter Expand Module - Image 3](https://m.media-amazon.com/images/I/71d4W9YfHAL.jpg) ![8CH PPM Encoder & Pixhawk I2C Splitter Expand Module - Image 4](https://m.media-amazon.com/images/I/71RMBW64qaL.jpg) ![8CH PPM Encoder & Pixhawk I2C Splitter Expand Module - Image 5](https://m.media-amazon.com/images/I/61T8OMr4++L.jpg) ## Questions & Answers **Q: is this compatible with Spektrum AR620 receiver?** A: Cannot.It used for PWM to PPM signal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not a Good Product *by J***E on March 24, 2021* I bought 6 of these and none of them worked!
