Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

The best Arduino Duemilanove is not made by Arduino team, is made by Olimex. So, Arduino should clone this board. Quote from "Arduino has been pwned by Olimex" article: [quote]I'll count down the top 11 complaints(regarding to the original Arduino, my note) again with fixes provided by the engineers at Olimex. #11. Accidental resets - Re-introduce the Atmel recommended noise suppression - check. #10. Analog sucks - Separate regulator for Analog, optional Vref for even more precision - check. #9. Shields cover reset switch - move switch - check. #8. Shields short out on USB connector - use mini usb - check. #7. Pin layout is Random - new set of .1 centered pins - check. #6. Frequency dependencies - provide replaceable crystal - check #5. Linear regulators suck - use proper regulator - check. #4. Pin assignment is Random - group power and signal together in Uext connector for GPS, ZIGBEE, I2C, etc... #3. Power wire in a portable world - add lithium charger and auto switching - check. #2. 5v in a 3v volt world - provide 5v/3.3v switch. #1. Battery life sucks - lose the firestarter and add real ULP Voltage regulators - check. And this is the short list, add real time clock support, 4 mounting holes, and Industrial temperature components and the Olimexino is far and away the highest quality Arduino Board ever produced for $29 on Mouser.[/quote] If someone want to enter in the Arduino world, this is what I recommend.

Totally Agree Olimex Makes absolutely BRILLIANT Boards The Bargain Basement prices are a BONUS. VK4MU MicroController Units |

I'm thinking at an Arduino with grbl firmware for my CNC but I have also other options regarding to the microcontroller. But yes, I would like to have Olimexino 328. Maybe in the future... Vasi Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

Also the PIC32-Pinguino boards such as http://www.olimex.com/dev/pic32-pinguino-otg.html Again from Olimex. John |

Yes, is a well made board but is mainly for Microchip users. I wanted to talk about ATmega based boards. Right now I'm looking at AT90USB1287 which can make a good and cheap development board, cheaper than Micropendous if I design and make it myself (as simple as possible).

thanks for the nice words :) I will confess that before we made this board I spent some time to read the Arduino forum and the Arduino users feedback, so we just listened and implemented what Arduino users wanted but had not in Arduino 2009. Vasi, AVR Mega are obsolete now, even Arduino Due ARM9 board will get obsolete until they release it. In March we will launch the super-duper Cortex M4 168 Mhz STM32F407ZGT6 which have 1MB Flash and 196K RAM in Arduino compatible layout for EURO 30 retail. There is interest in few developers from Maple community who are ready to implement the library support, there is already bootloader for F4, by end of March this board will be for sale and it outperforms Mega, Due, probably Tre too Cortex M4 have floating points and F4 is really powerful, Arduino team problem is that they too much follow Atmel and didn't look around what else is available when they decided to move to more powerful hardware |

Maybe the community of Arduino is not prepared yet to leave ATmegas... I think they will continue to grow future generations of engineers or at least hobbyists using ATmegas and then ARM (there are still users of 8051 and I also want to score it for my "portfolio"). They are preparing mainly ATMEL users (and I think this is the first major effect in working with Arduino and I think also Microchip finally realized that). In my opinion, an ATMEL user is better prepared to move to any ARM from the market due to the very similar development chain. Anyway, a Cortex M4 can be great for RepRap project (see? I'm also not a good target ). Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

Seeed Studio also makes an excellent Duemilanove, with several improvements over the basic version. It is cheap at US$22.50, with free shipping for orders over $50. I have bought a lot of stuff from them, including the colorful Seeeduino, with no problems. http://www.seeedstudio.com/depot/seeeduino-v30-atmega-328p-p -669.html?cPath=132_133 The Seeduino uses the same white connectors as their Grove system, which I also have. There are adapter cables between the Grove type connectors and the standard ones. I also got the last Wii Nunchuck adapter they had, but plenty of other places sell them. It's worth an hour or so to look over all the items they offer. |

My thought is that it's a very limited board, so little RAM :( I like the sound of the F4 board! Will it only be SWD? Or JTAG? John |

Is a nice looking board (prettier than Olimexino). Which one, it is user's choice. Probably, the price is the main factor for many. Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

My suggestion regarding to Seeeduino design: The Grove connectors must be angled (as is on Olimexino), to permit shielding same time. Even more because they already use it on Grove shield: Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

I confirm seeduino is better designed that arduino, just missing lipo charger, low power LDOs and dc/dc to have same functionality as olimexino |

"The Grove connectors must be angled (as is on Olimexino), to permit shielding same time. Even more because they already use it on Grove shield:" That is a good idea, though you should have been more clear that you Photo-Shopped the Seeeduino in your photo. Seeed Studio sells a package of 10 angled (or straight) Grove connectors for 99 cents, so at least the serial connector can be changed. In any event, the connectors only duplicate pins, and don't replace them. Conceivably, many users don't use shields anyhow. However, even if both Grove connectors are populated, you can still install a shield, with just a very small (insignificant) gap at the pin 5 end of the analog connector. The digital and power connectors fit perfectly flush, and all the analog connectors make good contact, due to the long pins used by shields. The Wii Nunchuck adapter is back in stock at $4. |

He he, don't tell me you searched for it in Seeedstudio shop! Sorry, you are right! Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

although not a Due etc... I think my fave has to be the Digilent Chipkit UNO32. the IDE is almost identical, the board takes all due Arduino shields, the programming code for it is transportable from arduino (the libraries differ somewhat), and its got extra pins and is over 5x faster. it`s a nice step into a New controller (PIC32) other than Atmel, it will take "grown up" code too. a genuinely nice segway into more advanced code and applications. I expect the Pinguino may be similar, although I don`t know anything about it`s IDE yet, I may get one later on in the year when I finish my current projects. I personally like the Due, as I can pop the 328p out and program a new one, this gets impossible with SMT devices. each board has their own good points I guess ;) |

The Ardweeny might be the smallest, and cheapest, Duemilanove version, at under $10, plus shipping. Ardweeny at Maker Shed It requires either an external USB-to-TTL FTDI-type cable or adapter, or else you just program the chip in an Arduino Uno (selecting the Duemilanove w/328 option in the IDE, since the Ardweeny 328's Duemilanove bootloader isn't compatible with the Uno or Uno R3 bootloader). |
