Forum,
Just some info for those who do not yet know:
1. The AlexMOS & Martinez board are completely different. We used both during our Beta testing.
2. The AlexMoS board has gone to proprietary GUI & Firmware while Martinez is still open source. You cannot run AlexMOS firmware on the Martinez Board.
3. The current physical board configurations are different.
4. The AlexMOS "group" are currently working on firmware updates & a 3 axis board. I do not know of any current work underway by the Martinez "group".
5. Several other "Open Source" GUI are emerging from new groups.
6. There are just a few "licensed" / "authorized" partners selling the AlexMOS board. They are listed here:
http://www.simplebgc.com/eng/buy/ Many do not show any in stock. We purchased some of ours from ARMBGC. Others from
http://www.ladroneshop.com/en/ Shipping to US took a while- about 2 weeks. The boards look different, come equipped differently, but both work the same. The ARMBGC is very nice as the board soldering is already complete....but more$$$.
7. The Martinez board works equally well. We got ours here:
http://www.altitudehobbies.com/multicopter-products/brushless-gimbal-controllers
8. The PID & PWR settings to make the same gimbal work correctly are completely different between the AlexMOS & Martinez boards.
It should be stated that this technology is very new & started open source. It can be
VERY challenging to get the settings & tuning done to get a gimbal that works perfectly, but once done, the payoff in video quality is the best I have seen. I am hopeful that as with multicopters a few years ago and where we are at today, that a "out of the box" Brushless Gimbal Controller (Like a Naza or WKM) with all wires, a case, a good manual & a good GUI (assistant) is in our future. Hopefully the future Brushless Gimbal Controller will have large enough ESC to handle larger motors for DSLR sized cameras. It is my "opinion" that the current boards do not. Gimbal motors are also emerging from many different manufacturers in many sizes & configurations...Perhaps a "standardized/ universal" bolt configuration will emerge so that they will all interchange. We designed "drive hubs" as part of our gimbal to deal with the different configurations.
Just some thoughts, comments & experiences for the Forum.
