Here are some screenshots of my Settings. The ESC were HK blue series flashed with SimonK Firmware, onboard Deltang RX used.

Quad X mixer settings - be sure to get the Motor numbers right!

Used HK blue series flashed to SimonK when doing the screenshot. Other ESCs may slightly vary!

Hi,

just want to add the info on my M4 BLDC expansion boards. There are now 3 revisions out there:

0r1: Power supply as shown in the first post

M4 BLDC expansion board 0r1 - connections

0r2: same as 0r1 but with M2 setnuts for easy mounting of the M4 (as pictured in the first post)

M4 BLDC expansion board 0r2 - connections

Revision 0r1 and 0r2 need to have a 5V source (BEC or from ESC) connected for operation. LiPo connector is used for voltage sensing only.

That's why I also developed a new revision - 0r3 - which is directly supplied from the LiPo (2S-3S).

ATTENTION:
Some components on the expansion board will get warm during operation! Take take of your fingers!

I/O connections:
M5: J2-7 (I2C1-SCL, PB6; MCU Pin58)
M6: J2-6 (I2C1-SDA, PB7; MCU Pin59)
M7: J2-10 (PC6, UART6-TX; MCU Pin37)
M8: J1-10 (PC7, UART6-RX; MCU Pin 38)

Voltage divider input to M4: J2-5 (SPI1-MISO, PA6; MCU Pin22)
This is only available when JP1 is closed and code changes were in place!

The data sheet of the M4 MCU is here: http://www.st.com/web/en/catalog/mmc/FM ... 5/PF252144

HI Jörg,

little confused. The boards i got from jussi are labeled as Rev4 online and on the license sticker, but the output in the console is HW ver 8 rev5, thus can i use your FW you posted here ?

Thanks

Boris

Here's the difference between M4 r4 and r5: http://autoquad.org/wiki/wiki/m4-microc ... rst-option

So if you have the wire mod, then you have an "r5".

Thanks okay get it the wired mod turns it into a rev 5 Didn't get that

Thanks

Boris

Sorry for asking questions that might be obvious to you guys, but does this look like a successful flash attempt ?

Rev 432 is shown after the attempt, but didn't even check what i had on before. And in the parameters the Lic key was still present shouldn't that be gone after a FW update ?

Thanks

Boris

Yea that seems fine. Sometimes I see that last "can't detach" error from dfu-util, sometimes not. It's trying to detach from the device (M4) and restart it, which I guess sometimes fails. The flashing part works consistently though, so just reboot manually and you're set.

When flashing with dfu-util, the params are preserved. Feature, not a bug! I know no one reads it, but the "Confirm Firmware Flashing" prompt in QGC will make the distinction and warn when params will be wiped. Among other things...

Hi Jörg,

do you know if there is any possibility to use it on a Hexacopter? I am thinking about building a NanoHexa with an M4 on it, but need to know if this is possible at all without CAN for the ESCs, as ESC32 would be to big for the project.
