Raspberry Pi vs all

DISCOVERY_F0ST produces some of the most cheap development boards: the Discovery series. We have already reviewed the Discovery F0, comparing its features with Arduino and MBED http://www.hwmakers.eu/microcontrollers/stm32f0discovery-review/

ST Discovery F0 is cheaper than both MBED and Due but it is almost four times bigger than MBED and the last one is simpler to use, thanks to the excellent job made by the MBED team and by the community.

Digilent develops one of the most interesting developing board compatible with Arduino, chipKIT UNO32:

UNO32In our opinion this board is a lot better than Arduino, has been designed using better components, is well designed and has got a better layout, is more powerful and is cheaper. The board can be programmed using Microchip MPLAB or with a customized IDE very similar to the one used by Arduino:

UNO32_IDEThe UNO32 is based on a 32 bit microchip microprocessor, model PIC32MX320F128 and can be used with many Arduino shields but remember that this board is not 5V tolerant. You can find more details on the official page: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,892,893&Prod=CHIPKIT-UNO32

Now we want to spend some words about one of the most well designed circuit for the internet of things (IOT): Openpicus Flyport http://www.openpicus.com/site/products

FLYPORTFlyport is based on a microchip PIC24FJ256 and a WIFI module of the Microchip MRF24W series. The framework developed by the Openpicus team makes easy the programming of the PIC microcontroller and hides most of the programming complexity in order to have a very friendly way to develop IOT systems with a customized web server which is developed within the framework.  It is very fast to get start with the Flyport using the Grove Nest board and its sensors breakout boards:GROVE_NEST

NEST_FLYPORTThe IDE is simple and easy to use and include a wizard which allow a intuitive way to configure all the network parameters available with the Flyport:

WIZARD MK802 is the most “consumer” of our comparison. Rikomagic develops new models so fast that it is not easy to have available the last revision:

MK802The MK802II is based on SOC Allwinner A10 but the latest version (MK802IV) has been designed around a 4 core chip. The 802II is distributed with Android Ice Cream Sandwitch 4.0.4 but is possible to use some optimized linux versions:

http://store.cloudsto.com/downloads/lubuntu-1204-rikomagicuk.7z (Lubuntu 12.04 LXDE).

Linux can be installed on a microSD so the original Android system is not delated and it is possible to go back to previous OS anytime.

There are many other development boards that can be compared with Raspberry Pi and their number is growing every day. Raspberry Pi has began the challenge and we makers are ready to choose the winner.

Conclusion: there is not a real winner because there is not in absolute the “best” development board but it depends on the application you have and its requirements. You can choose from a huge number of alternatives: you can looking for the most powerful (but it is not always the best solution), the one which requires less power, the cheapest, the smallest, the simpliest to be programmed or only the one you prefer.

    In terms of learning curve may be PLC is the better choice.
    What about stability of control systems based on the PIC24FJ256 compared to ARM cortex M3?

    • admin says:

      The stability should be the same in the same working conditions, working respecting the MCU specifications. Maybe some little difference can be appreciated by accurate measuring.

    I personally think that the beagle-bone is a likely contender, and maybe the beagle-board too! Otherwise, nice post!

    • admin says:

      I agree with you, beagle bone is a very interesting and powerful board which deserves to be included but we have not yet one to test.
