Hi all

I'm looking for a replacement for the Arduino Due I am developing an application for. The Due is a very nice board with a lot of connectors, i2c, sdi etc. but is not reliable and not really made for a commercial environment. I've looked about online but there doesn't seem to be anything that has similar functions. What I'm looking for is :-

CPU around 70MHZ or faster and 32bit (64 bit math capable)
USB power
512k (or more) program flash memory
100k (or more) SRAM
I2C and SDI bus

I don't care about the CPU but cost is a factor (£100 or $120). I know there would be (hopefully!) a few answers to this but it's very hard to find anything that fits this list. I'm not a great electronics engineer so a complete development kit would be great and hopefully libraries too. It also has to be simple i.e. no networking/Linux etc. so the Pi wouldn't be any good as it's just too complex and hard to lock down.

hi,
Looking thru the web I do not see a commercial grade version of an upgraded Duo at the budget price you have posted.
This link may help.

Thanks, very useful link. If I was to increase the budget, what sort of things would be available?

Asking for 512k Flash and 100k SRAM is very demanding.
I would be looking at an STM32F MCU, for example, STM32F103RG.

 

True. I could work with 256K ram instead.

PJRC has a line of Arduino-compatible boards that might suit.

 

Thanks for all the replies, I will now do some reasearch!
