Which arduino board?

Hi,

I just found out about Hexy, and want to know more about the hardware configuration.

What battery/voltage does the Hexy run on?
What is the processor (I guess it’s from Atmel family since it’s Arduino based)?
Is there memory/storage on the Hexy, or does it need to run plugged on USB?
Can a second Arduino board be connected to control the Servotor32 (add more processing power to the system).

Thanks!
Antoine

The servos run on 6v, with the logic running either off the USB, the 6v (assuming that doesn’t dip too low), or an external battery that’s 5v+ (if the servo battery dips too low). You can hot-swap the power, too. As long as its plugged into some sort of power that’s above 5v, it should keep going.

The chip is the Atmega 32u4 (same as the Arduino Leonardo)

There is the limited programming storage that comes with the Arduino. Its enough to program a number of simple moves and autonomy code. You could add extra using external chips. (Although an SD card would be hard given the SPI bus is used a lot for the servo movement).

External Arduino is easy. It talks over serial, either through the USB port or the TX/RX pins broken out below.
