Autoquad team proudly presents: Autoquad ESC32
ESC32 End of Beta
The AQ team is delighted to end the beta for the ESC32.
The ESC32 has proven in the beta to be highly stable and working well for a number of motors. We have recently introduced some changes to the main code that makes it less susceptible to disarms due to noise in the PWM lines.
Also, CAN-bus is now available for ESC32, and with that we get a 3 times faster update rate, and full feedback to the FC.
The HW is unchanged, except for the fact that new batches will come with the CAN transceiver mounted from factory.
Otherwise specifications are still the same, and there are no immediate plans to release a new version.
We are however working on a concept for a Version 2 of ESC32 that will support up to 10S, but no decisions have been made about production yet and we need to put it through internal team testing before releasing it to the public.
Viacopter is proud to present the Autoquad ESC32. In short it’s a 32-bit gatedriven, all N-fet Brushless ESC with extremely fast throttle response designed for use in Multirotor helicopters. Autoquad ESC32 is designed and developed by Bill Nesbitt. It’s a closed source hardware with open source code written in C.
Bill Nesbitt´s blog post about ESC32 on DIY Drones
- STM32F103 72MHz 32bit ARM
- All N-FET design with gate drivers
- 2S through 5S battery voltage
- Option to power logic side via UART or PWM IN +5v
- CAN transceiver hardware support onboard
- Firmware written completely in C
- Cortex SWD connector pads for real-time debugging
- Communications ports: PWM IN / UART / I2C / CAN Bus
- Communications protocols: PWM IN / CLI / binary / 1-wire / I2C** / CAN**
- 4KHz to 64KHz PWM out
- Current sensing / limiting with real shunt resistor
- Virtual current limiter
- Regenerative braking (experimental)
- Closed loop control modes
- Lot of available RAM / FLASH for experimentation and development
** I2C and CAN drivers not yet released!
Important note from ESC32 creator Bill Nesbit about current levels attainable:
All parameters can be set by user over a USB-serial interface using the AutoQuad QGroundcontrol widget or CLI.
We will continue to evolve the source code, but we hope that people will join the effort and help us develop it further. Because of that, the source code is released under a GNU/GPL license. That means you are free to use and modify it, but you are required to publicize changes you make. If its good we will include it in the public branch! Go to forum.autoquad.org for more info.
Preliminary manual is attached here for reference. We will not run support for it here, but we invite you to come to forum.autoquad.org for more info and support. There is not a huge entity behind this and all development was done by dedicated volunteers, and that is part of why we can release this stunning piece of hardware so relatively cheap!
A lot of people has contributed to making this possible – first and foremost Bill Nesbitt who designed it and made it available – but also the Autoquad team has been vital in making this happen. Thanks, guys!
Special thanks go to TimeCop for helping out with initial hardware design and prototype production and to SimonK and Quax for helping with the FW and testing!
Autoquad ESC32 is manufactured to the highest industry standards in Germany, using the best components and production methods available. They are fully ROHS-compliant and our manufactorer complies with German law for environment protection and worker safety. Each board is tested in factory before release.
You should understand that ESC32 is a “work in progress” and that new features will be evolved but there is no guarantee against bugs or “operator error” so this is why we are designating it a Public Beta. We are confident that “first movers” will know and understand that!
However, having flown many hours with it and tested extensively, we do feel confident that it is working as it should and that bugs we know about has been resolved, so we are proud of being able to release it into the world of multirotors at this time!
On behalf of the Autoquad team – we hope you will enjoy this excellent ESC and help us make it better!
ESC32 is up for ordering now. You can get them from Viacopter and Flyduino

You might have heard about "ESC32 Compatible" alternative hardware these days.
We´re sorry to tell you that our small team can´t bare support for 3rd party hardware!
Original (only available at trustful vendors)
"Compatible" (example, can be purchased at various places)
In general there´s nothing wrong with offering alternative hardware that uses our Open Source Code.
It´s also ok to use our ressources, constantly grown over the years like the Wiki, Downloads & Documentation, Tutorial Videos and all that sexy stuff freely available at our sites & servers.
But our project is driven by volunteers, with hardware covered & supported by 2 online shops taking the full finacial risks for prototyping, small beta batch productions, parts sourcing and production runs.
So this is rather no business model than a way to save their azzes before they go broke.
So please have mercy - don´t bother us with problems, we didn´t cause!
In return for our constant efforts you could contribute by calibrating certain prop/motor combos so we can fill our database. But don´t expect us to look at your calibration data if you don´t provide a proper proof of functionality.
In case you need help, please go to the socalled "RTF32" thread that deals with the alternative hardware:

I thought ESC32 is under open source license. i have been following bill's work on diydrones and i do not think profit is allowed under such conditions.

i searched "amp" using cntrl+f on both this page and the link...
but now i see. sorry i feel dumb.
they do look nice...something from the community

they do look great.
If someone comes up with a nice power distro board like the Mikro boards for their esc's, these new ones would be ideal for some custom builds!

It's all about the license that the AutoQuad Development Team and Bill agreed on.
Bill made sure no greedy source grabbers will be able to throw clones onto the market too soon.
Rest assured that the AutoQuad Team and the vendors will try to keep the prices as low as possible.
btw: we set up a forum for discussions here: http://forum.autoquad.org

So although you may be a bit biased toward esc32 since you're on the dev team, how does it compare to simon + atmel escs.
