The mRo Pixhawk flight controller is nearing retirement and we are reaching the end of our general stock. We encourage you to explore our newer, more advanced, and powerful flight controller options. If you absolutely need to purchase this model, please contact us for a custom production quotation.
Warning gorilla hands: DF13 connectors are extremely fragile. mRo has reinforced most of them by adding vias under the pads; these will act as "anchors", making them a little stronger. Still, some pads, like the one used by the Buzzer connector, cannot be reinforced due to the signal density below it. You should never use more force than that required to flip your home wall light switch. You can find several videos on YouTube that explain how to remove it. Note that if you break it, mRo will not replace it.
You might wonder: why the pink foam? We are including this antistatic open cell foam, so you can replace it or upgrade it. It will keep your barometer or altimeter sensor from misinterpreting direct wind blowing into it as a change in altitude. We strongly recommend that you change your original foam, especially if it is black. The black foam is "closed cell" and doesn't allow your barometer to properly notice pressure changes, which in some cases, may have a big impact on pressure differential.
Time-tested, extremely robust Pixhawk 1 is coming back with a lot of improvements! We know there are many Pixhawk 1 clones out there and a few of them are probably already damaged after years of use (we have seen everything from bad crashes, short-circuits, and water splashes). This product is the best opportunity to bring that Pixhawk 1 back to life and save a lot of cash. You don't have to repay for packaging and cables you already have or don't need.
We will soon be releasing an OEM version (with improved enclosures, SD cards, damping foam, and stickers, but without cables or accessories) and finally the standard version with all the accessories and cables as the original Pixhawk.
This Pixhawk has a few improvements that never made it to the public, including STM32F427 revision 3 that corrects a bug that limited the Pixhawk to 1MB of flash. Note that most of the original Pixhawks do not have revison 3, for it was not available at the time they were produced; make sure to ask before buying.
