Discounted price has again disappeared, I missed opportunity to purchase a second board ... :(
So, I will put my eggs on stm32duino OSHW board ... :)

Yes ! I've mentioned it in this post of the current thread : viewtopic.php?f=39&t=1162&start=40#p15038
The reason is that older PCB revision wasn't compatible to Arduino Mega but newer revision is.
The bad side of the new revision is that silkscreen is now only printed on bottom side, there is no more pinout silkscreen on top.

It is probably related to the fact that they change some pin layout for Mega compatibility as mentioned here :

Note : on newest board layout, the PB6/PDB7 are switched with the PD6/PD3 to get pins compatibility with Arduino Mega.

thank for you reply .
After lot test with mbed compile OnLine Serial.h:

Code: Select all

Serial Serial6( PB_6 , PB_7 )  = Serial Serial9( PA_9 , PA_10 );

Serial Serial8( PC_6 , PC_7 ) = Serial pc ( USBTX , USBRX );


There is only 2 USART .. :cry: :cry: :cry: :cry: :cry:

Have you get a idea for acces to lot of USART ??
