  • Luke, the Raspberry Pi wiki states that "there are approximately 16 spare GPIOs, which are brought out to 1.27mm pin-strip." There are also 3.3v I2C, I2S and SPI pins available. I'm sure many things can be done with those.

  • That's why Konstantin is busy with his canBLC: it is using the industrial can bus system, which is a lot more reliable. It's still in development, but I think his quad will fly in the next weeks with it.

    Blog (only german,sorry):

  • Developer


    I2C is a toy. If you want reliability take a bus designed with industrial strenght in mind.


    I2c has not been designed with reliability and robustness in mind. it is primarily a simple protocol and basic hardware interface without galvanic isolation for interfacing Integrated Circuits on PCBs, not more.


    I would never use that on my frame for ESCs.

    PWM is unidirectional

    with I2C you can get Informations from thes ESC's like powerconsumption or temperature.

    You're right that I2C can produce some problem, but with a short busrecovery the communication will be reastablished.

    I never had an I2C problem with my MK.

    An other point is I2C and STM32F1xx . I think these guys will never bcome friends ;)

  • I see a lot of talk about I2C esc's and I must say, I think PWM is much better. Take a look at the MK forums, i2c is a delicate interface, there are lots of lockups and having an i2c>pwm converter is pretty much mandatory for any expensive payload, heavy lift systems.

  • Helldesk, that's an excellent project. Though not really the same purpose since there are no universal I/O pins on the Raspberry Pi board.

  • I am also keeping an eye on the Raspberry Pi, a $25 computer based on a Broadcom BCM2835 SoC that could be used for quite a few purposes. It should be on the market next month!

  • Great thing for a reasonable price.

    I wonder what's the power consumption (idle, avg, max) with no IO devices attached?

    What's the exact weight?

    ps: just curious, why not Cortex A9?

  • I think we need to do that, like amazon prime ;) looking forward to that mail
  • Distributor

    Your latest shipment had left 5 hours ago, sure we could come to some sort of postal agreement :)


    Not Looked at the price just yet, the DZ2 stopped it from being stocked in store as I was doing a lot of running about, I will mail you in the morning with some costings.
