Has anyone else used the OSEPP brand of arduino compatible products? they are readily available at Fry’s Electronics now. Any know issues with compatibility?

From this link, it seems to be a 100% compatable design. Many firms make Arduino compatible designs as it is a open sourced design.


I wasn't aware that Fry's was selling Arduino stuff, but it appears they have a nice selection of stuff:



Man, every time I hear about something Fry's is doing, it makes me wish even more that there was one near me.

it makes me wish even more that there was one near me.

The time/distance you spend driving there will be negligible compared to the time you spending wandering around aisles and aisles of stuff looking for what you want. When you find where that is, it'll be in a locked cabinet. It'll take half an hour to find someone to look for the person with the key. It'll take that person 20 minutes to get there, and they won't know squat about what is in the cabinet.

If you order something online before you leave home, it will have arrived before you get to Fry's and back, on a good day. Even if it is coming from China and is back-ordered.

Fry's fan? Not me.

I just purchased an OSEPP Uno today. This was to replace an Amazon true Uno I had fried last night.

Was about to start getting quite upset at Fry's, because after the first upload test it would not take any more uploads, good old "stk500_getsync resp 0x00", which the forums say could be from any possible cause and then some.

One suggestion did work, which was to try a different "board" - I had, of course, set it as an Uno.

Turns out that when I tried "duemilanuove or Nano 328", things worked.

Now, if I can get my silly 10.10 Ubuntu to Gnome Classic, I will be a happy man...

The OSEPP "Pro Minis" were flashed as if they were Unos. Make sense that they'd flash the Unos like they were something else.

And yes, my OSEPP Uno thinks it's a Nano, too. Also bought from Fry's ... probably the same Fry's you bought yours from :)

Just bought one of these today at MicroCenter. The back of the package had a sticker advising to use the Nano or Duemilanuove as the board type. A trip to their web site mentioned an issue with the bootloader and said to use the above settings instead of Uno…

Honestly I’d rather use that bootloader than the Uno.

The board seems to be well made and works exactly as I needed it to. Just like my other clones/compatibles.

Just bought one of these today at MicroCenter.

That's not so good. Did Sparkfun lose their relationship with MicroCenter? As far as I can tell, OSEPP exists to undersell more participatory Arduino manufacturers (Arduino, adafruit, sparkfun, etc) in the "wholesale" sector, while not offering as much in the way of end-user support or innovation. (They CLAIM that they're planning to innovate. We'll see. It all feels slightly sleazy...)

Honestly I'd rather use that bootloader than the Uno.

eh? How come?

I’ve completely had it with buying OSEPP products – I had the “Pro Mini flashed with UNO” boot loader problem in spades. Just when I figured they solved that problem, I found a mess of 5 volt Pro Mini’s that were flashed with the 3.3 volt Pro Mini boot loader. And they really were 5 volt Pro Minis.

Time for a boycott. That and time to spread the word that they have crap for QA. My guess is they’ve outsourced manufacturing to who knows where and are don’t =zero= QA on what’s coming off the line.

osepp products on sale at fry's

uno for $24.99 mega for $49.99 (good deal I think) pro board, pro mini, ftdi breakout board for $14.99 (good deal I think as well)

as for bootloader issue, you can always reload it with optiboot bootloader for uno. it is very easy if you have another uno or mega card, just use Bill Westfield's nifty optbootloader program to reload the bootloader. https://github.com/WestfW/OptiLoader

as for bootloader that requires you to select a board that is different from the actual board, adafruit still sells 328 chip for use in UNO programmed with their booloader that requires you to select board as DUEMILANOVE with ATMEGA328 yet nobody complains about it.

From what it sounds like its sketcky, I’ve bought 3 mega 30$ ea, 2 unos 20$ea, and a nano 15$ from ebay and never had a problem with any,
so far
unkown chinese dealer : 6

Bought a OSEPP prototype board which had many doodads in a kit for $9.95 (now carried by Radio Shack in lieu of the Arduino proto board. The OSEPP comes with NO documentation, very poor silkscreening, and sadly it 'killed' my Arduino UNO. Never had a problem with a genuine Arduino. Not much of a saving there.

From this link, it seems to be a 100% compatable design.

They use an FTDI instead of an ATmega16U2 and the auto-reset diode is missing. It’s a Duemilanove with a surface-mount processor.

You may as well get a Duemilanove from Amazon for a few dollars less.

I'll never buy anymore of their "stuff". No support, quality issues. The I2C shield mechanically doesn't fit on an Arduino UNO. "SK6" jams into the ATMEL, and won't let the board piggyback as intended.
