ARMando...

If you made your own board, post here, unless you built a Maple or Maple mini clone etc

"Linux" jumper :?
I'm looking forward to the specifications of the board !

Hi, the "Linux" jumper is not for what you are thinking... :mrgreen:

It is part of the "autoreset" circuitry for automated uploads from Arduino IDE using the internal serial bootloader (when a linux host is in use) with the ST core.

I've implemented here the circuit used for the first experiments here in this previous post.

I've attached the "preliminary" schematic here (zipped file because it seems a .pdf can't be uploaded).

More, I wanted a "standard form factor" board but that it could easily be used with a breadboard (like a breakout board) too.
I'm testing here a way to directly connect it to 1 - 4 standard 830 points breadboards.
They should form a fairly rigid assembly.

Here a test with 3 breadboards using a "paper pcb":

I haven't done connections to the red/blue power zone of the breadboard because I realized that it could be too "restrictive" mechanically.

Using standard nylon 1cm spacers it is possible use it as a "normal board" too, because spacers are more long than bottom pin headers so they don't touch the table... (and they don't "interfere" with the breadboards in that position...)

Just assembled the first board and currently testing it (with Arduino IDE too, it is compatible with the Discovery with the same MCU using the official ST core and the serial embedded bootloader...)

Here a demo about the "breadbord friendliness"...



I'll publish all the details after some testing.
