Maple R3 now shipping

Leaf Labs is now shipping the Maple R3 boards. [Phil Burgess] gave the platform a look just before launch last fall and the high-powered prototyping board is now even better. New features come in both hardware and software varieties. The bootloader can now be upgraded without additional programming hardware, there’s hardware SPI and I2C interfaces, and a newly-polished IDE for Linux and Windows. At $50 it’s a good way to get access to the power of the ARM Cortex M3 processor at the center of the board. We’ve seen several projects that use the mbed, which is in the same class as the Maple, but we’re waiting to see what you’ve accomplished with this little devil.

    I want one! Looks like it can even charge a LiPo — nice!

  2. osgeld says:

    wonder how long before the trolls notice its in an arduino form factor and their ide uses the same functions

  3. NatureTM says:

    I think one just did!

  4. Mathmatica says:

    Hey guys….im a long long time reader(Engaget LONG), i think i’d actually buy this with the arduino even thou i wanna get my hands as dirty as possible because there both compatible? Oh and lasty its not related but i think this site would benifit from seprate microconroller brand name tags

  5. Mathmatica says:

    Lol i look silly now, i dont use tags anyway

  6. osgeld says:

    nah, I read about this on arduino’s forum, which defiantly proves that I am not a troll

    lets recap just in case there is any doubt

    I use and love arduino, and I read something

  7. This looks like an easy & cheap way to try out the ARM’s – I’ve been meaning to see what they can do.

  8. osgeld says:

    yea it does, If I had an extra 50 bucks to burn on a toy right now I would have already bought it

  9. Kyle says:

    I’m surprised they haven’t decided to fix the form factor on arduinos such that protoboard can be used. just need to duplicate one of the headers…

  10. Shadyman says:

    @Kyle: You mean like the Boarduino?

  11. Guest says:

    “At $50 it’s fairly overpriced” Fix’d

    This board is more powerful and is programmed via a serial port (built in max3232). Oh and it’s less than half the price of maple.

    Extra bonus, it can be plugged into a breadboard cause it’s in a DIP for factor.

  12. Victor says:

    I find that seeedstudio has the best duinos with both the weird spacing and standard spacing all on one board

  13. tim says:

    can someone find the schematics ?
    there seems to be nothing on the link

  14. Charles says:

    I agree wit Victor. Seeed Studio’s seeeduino is the best arduino clone out there because of the extra set of headers with standard pin spacing. Seeed Studio is also the manufacturer of the famed bus pirate and a few other cool tools like the DSO nano.

    I am going to order one of these maple leafs next week and see what I can come up with.

    I also think HAD could do with a uC tag.

  15. Halo says:

    For schematics just click my name.

    Try looking into Maple a little harder before attempting to compare it to others.
