Pixhawk is a great autopilot, we love its robustness and rich sets of features. Nowadays it is a de-facto to low cost autonomous vehicle application.
There’re always some changes you want to make in an open source design, this rule also applies to Pixhawk. First, I want to make it smaller, to fit it into a f5B glider fuselage, with built-in dampers and a plastic shell could survive a hard crash. Then I want to make the sensors to be replaceable, so I can test new MEMs gyros. And lastly, I want to make the IO completely customizable to my specific application, eliminating 3-pin RC connectors, better fixture to a larger avionic payload motherboard, or an array of Pixhawks without messy wiring.
So in the last winter, we had it done, named it P9X
Some quick facts about P9X: (might subject to change due to its beta phase)
- 80mm x 50mm x 17.2mm box made of 1.5mm thickness mold injected PC/ABS
- 43mm x 50mm core PCBA size
- Tested with Ardupilot
- Tested with QGC 2.7 version PX4 firmware
- PX4 master built not yet running (maybe a firmware issue)
- Total weight: 45g
- Connectors fully compatible with Pixhawk
- Integrated silicon rubber damper (need help in axle alignment test)
- 4 copper nuts embedded for M3 screw mounting (dimension: 38mm x 25mm)
- IMU sensors swappable (need soldering)
We need your Help!
The first 50pcs batch is out, we have invested in inject mold, silicon rubber mold, silk screen printing. We want more testers and a crowd funding campaign, before that, we want to make sure this hardware revision has no serious design issues. If you are experienced user, developer, embedded engineer, please consider purchase one of these beta samples and send us feedback.
How to get one.
Back in the last year, Raspilot project generated no income, Emlid and Erle Robotic has inspired by its design then they have made their similar design products. I don’t want to bankrupt in my hobby, and make it serious to be a self-employed job. So no more free samples.
I want to sell these 50 pcs unit for 150USD each, with Aramex shipping from Shanghai, China. Please give me feedback about the price.
