And $9 each and you get a pair of genuine buttons, too. That comes in less than $30. Just a thought. Jon
Would really like input/opinions on the ARM/CORTEX M3

Hey, Jon. Nuts, I already ordered from Digi-Key. However, they are not shipping over the holidays so maybe I can cancel and get the cheaper version from Mouser and get it quicker. Are you certain that what you suggested is the same as what Linnix suggested? Nevertheless, I ordered two of them and, from Mouser as Joe Chisom suggested.

Took your advice, Joe. I ordered two of them. Hope they, too, get here the next day. I am near Salado.

Joe, It has been less than 24 hours since I ordered and here I sit with the ordered parts in hand. THAT IS SERVICE. Again, thanks for the help.

THAT IS SERVICE.That kind of service from companies like Mouser, DigiKey, and Newark, is what makes it possible for very small companies like my own to compete in niche markets. An engineer with an idea can get things done without all the overhead of purchasing departments, manager's permissions, etc. etc. Now if I could only get the accounting departments at my customers to turn invoices into checks with similar speed! ;-)> > Again, thanks for the help. > > Joe > >Mark Borgerson> On Tue, 28 Dec 2010 09:35:04 -0600, Joe Chisolm > <jchisolm6@earthlink.net> wrote: > > >On Tue, 28 Dec 2010 00:03:03 -0600, justme wrote: > > > >> Great.

Needed to other some parts. Digikey and Mouser don't stock them, and need to buy 1000 and wait several weeks. Canadian F* got them, and better prices in small qty. Got in the web. Entered the order. Punched in credit card number. Submitted... Nothing happen. Got back to the main screen. Reg. with new account. Login with new account. Wrong Password!!! Click on forgot password link. Check my email. Nothing there. Tried "forgot password" again. Still Nothing. Call them. The one lady handling all internet sale was out to lunch. Tried again the next day. She needed to email me the account form. Next day, still nothing in email. Forget it, I'll buy 1000 from Digikey. If I have so much trouble before paying, what would happen after paying F*.

If I have so much trouble > before paying, what would happen after paying F*.I must admit I've made design decisions based on what's available at DigiKey only to get bitten on the butt two years later when the parts were out of stock with 12-week lead times. In general, when they're out of stock at DigiKey, they're also hard to find from other sources. Alas, that has happened when a customer placed an order that doubled the annual volume for a particular board. They hate it when you say you can deliver 10 this week, but the next 30 may be 12 weeks out. Of course, those orders always come in just before vacations or holidays! ;-( Alas, for companies with small volumes in niche markets, inventory control can be more magic than management. I don't want to retire in a few years with two years worth of parts unused on the shelf. Mark Borgerson

I will do a pcb prototype soon, probably with tqfp48 (STM32F103C8T6) and micro USB. Look like the board has 8MHz crystal. Wonder why they didn't use 25MHz.
