We are planning to use the MPU capabilities for more purposes like start or stop the robots just knocking on the table where it stands or to create a small drone just using 4 small dc motors. There will be an i2c bus as well for external sensor as a LIDAR

Regarding the placement of the IMU: it is curious how the final placement of the IMU does not change (considerably) the behavior of the B-robot. Actually, you can put it on top of the robot and not noticing any misbehavior at all. The only problem of using a long i2c: noise and EM interference.
Right now the first desing of the new brain shield has the same footprint and Arduino have but adding:
- The M0 processor
- 2 i2c buses
- 3 stepper motor drivers sockets
- ESP Wifi module
- MPU9250 accelerometer+gyro (way better than the MPU6050)
- SPI port (to control LEDs and others)
- 1-12 volt 1A PWM configurable output (to control air pumps, LEDs, reles, power servos
among other features

We will post info as soon as we have it ;-)

Nice changes and improvements! Have you also considered upgrading the ESP module from ESP-12E to ESP-12F?

Hi,
Is the M0 integrated on the board (no need for an Arduino M0 board like this: https://www.ebay.com/itm/SAMD21-M0-32-bi...2401159523 ) ?

If so I guess it`s not a new shield, but a new brain?


something like this may be an idea if vibrations is a problem?




M3 Rubber mounts


For installation in the PCB (brain) mounting holes (many flight controllers use it)


Nema vibration mounts

One more :-) is it going to support OPENMV camera compatible like the new Blimpduino 2?

Well, you are right. the M0 will be integrated so there will not be a need of and external Arduino. It will be an Arduino by itself, not a shield.

Thanks for the idea of the M3 Rubber mounts, we will take a look at them (get some to play with) :-)

Yes, there will be support for OPENMV cameras, Actually, there is a connector on the blimpduino PCB to connect the camera
