Thanks, fixed.

The same board (apparently) but without the Ethernet device is now available:

Probably the E suffix is for Ethernet?

Olimex have released a few new products today, but not the E407! The H407 also has a USB host.

Now to wait until somewhere in the UK stocks it

If you download the schematics from github

https://github.com/OLIMEX/STM32F4

The E407 is there xD

The H407 looks good too, it should be easy to support starting from the E407 board files, especially with the board files generator now under test.

True, but unfortunately the E407 schematics are still in the first revision. They will only update them once the board is release...

[Giovanni]

It should not change, the only difference I know is the xtaf frequency, on the schematic is reported as 25MHz, it will be 12MHz of production boards, even my prototype mounts the 12MHz xtal.

It's taking shape:

I wrote a small review comparing it with the Discovery: http://www.chibios.org/dokuwiki/doku.ph ... ry_vs_e407

Any suggestion on how improve it? fixes? things that should be added?

Hi Giovanni,

I think you have a typo in this paragraph:

Last but not least the price. Both boards are really cheap, the STM32F4-Discovery can be found around 17€ from various distributors, the Olimex STM32F4-Discovery is priced 39.95€ for a single unit but the price goes down for quantities.

I think this should be

Code: Select all

Olimex STM32-E407

Thanks!
