M4CAN + rOsewhite Rachel

Postby aBUGSworstnightmare » Wed Feb 25, 2015 7:30 pm

Hey guys,

had a hard time dealing with some ESC32V3 samples but now everything looks promising 8-)

Re-build my rOsewhite Rachel frame with a new setup:

Frame: rOsewhite Rachel (http://www.rosewhite.de/en/rachel)
ESC: ESC32V3 protoytpes, connected via CAN
Flightcontroller: M4 on M4CAN expansion board (viewtopic.php?f=40&t=3857&start=70#p30957)
Motors: T-Motor AirGear 350 set, AIR2213/920KV, will use it with the stock T9545 props (http://www.rctigermotor.com/html/2014/C ... 0/279.html)
Battery: 3S

Here are some pictures!

Nice setup, Joerg!


btw: if you don´t get a GPS fix, this might be the reason why:

Better run the antenna cable in another way, e.g. on the outer corner instead of through tha hole...

There she is: Ready for Duty!

As you can tell from the pic there's not much gap between the tips of the props. Maybe I need to get hands on 9x3 CFK props later .... let's see

The only problem now is her 'male voice'! Maybe too much steroids :P

Adam had posted some female voice samples for the v3 some time ago - might fit the girl named Rachel better. ;)

Now that the ESC32V3 series production is at the doorstep I've started to replace the prototypes by series production.
The supplied 470uF cap is good for 6S but it's a little bulky so I had to find a new place for it. The V3 version I'm using comes without the micro USB socket --> USB2UART needs to be used (as with ESC32V2).
SANY0062.jpg
3.5mm bullet connectors were soldered to the motor connection pads. Connector on the I/O is a MicroMatch 10-pin. My primary interface is CAN --> wires were added in addition.

A MicroMatch 10-pin connector (i.e. Digikey A110869CT-ND) is added to the I/O pins. The connector needs some 'hacking' (bending the pins on one side by using a plier) to make it fit. It allows to use the UART (only 5 pins were needed (DTR is NC)), PWM and CAN interface from a cimpable connector (i.e. Digikey A107014CT-ND).
SANY0063.jpg

SANY0064.jpg
I've stared with soldering the UART side, then bend the contacts on the CAN/PWM side to mate the solder pads and soldered them in place finally. You can clearly see this ESC32V3 version has no USB socket mounted.

470uF/50V cap is wrapped in heat shrink and placed on the ESC32V3

SANY0061.jpg
Picture shows how I bend the connector leads.

Also started to prepare a .XML-file for QUATOS. With a AUW < 1kg this Rachel config can be used with the FOC QUATOS license that comes with the M4.
Thanks to Fred we now have a tool to visualize .XML files in 3D (refer to viewtopic.php?f=48&t=4456 for the total story as well as the tool itself). This is very helpful for finding errors in the config file.
Here is what the Rachel's .XML look like:
