Share Goo 8CH PPM Encoder & I2C Splitter Expand Module Breakout Board for RC Pixhawk PPZ MK MWC MegaPirate APM Flight Controller

Exactly what I was looking for. I use this for igniting onboard rockets on my FPV airplane, i have it on a 3 channel switch and it works every time! Using a very small 3.7v 600 mah battery to provide the charge. Awesome! Buying another for other uses!

Similar to one of the other recent reviews, at least this version of the PPM converter doesn't work properly. When all eight inputs are plugged into a known good RC receiver (tested with servos), the resulting PPM signal has channels 1-4 duplicated on channels 5-8 (and channel 7 and 8 are duplicated back to channels 3 and 4). When the case is opened up, the circuit board indicates it is version 1.3, and it is not obvious whether an AVR ISP can be used to upgrade the code.

Connections on both sides of the circuit board seem weak. I plug the connector in and cant tell if its seated right or if I have a good connection. I pull slightly to test and plug easily pulls out. I never ended up using as I doubted the connection would hold on an RC vehicle. I also ended up finding a way to use SBUS instead.

I dont know why, but when I had one channel plugged in, it worked correctly, but when more than one channel was connected, it didn't work anymore. One channel for the receiver would control more than one channel on the pixhawk.

Complete waste of time to buy this crap of a product.
