Hi everybody, I have just finished this low cost version of APM2.5 because it's difficult to buy a original board in my country, so I decided to build my own hardware with two layers PCB :)

I have solved some bugs in hw such as:

I also added a filter for AVCC for better adc result:

Modified PPM Encoder which is more simple in connection than original:

with one 3.3V SPI extension to connect with other 3.3V SPI device

The hardware worked well. data from sensor:

Next test, set up it to frame with full supports for a quadcopter and...fly

This version costs about $53, nice price, hah ^^

Some pictures (Dimension: 56mm x 56mm)

Bottom, I'd like to change original name for my new board? Is it OK?

I'm considering to open this hardware after I finished all test for this board. Someone can tell me any legacy problem when I share my Altium design to open source community?

Note: xtPilot is a modified hardware based on the APM2.5 open-hardware project.
