Evenin'

Everybody knows the Carambola2 (or better said the used CPU) should have 2 * UARTs (o;
What do you use for attaching a 2nd UART to the Carambola2 module?

The end project is a Volumio like audio player which has also a DAB+/FM module on board...and this module can be controlled only by UART @57600 BAUD...

@gedass: how does it look with Lima and Rambutan projects (http://downloads.codico.com/misc/AEH/8D ... evices.pdf)?

Yes you are right.
Rambutan (QCA9557) and Lima (QCA4531 & QCA9531), commercial and industrial versions.
Rambutan module has 2x serial ports and free SPI port.

Any estimates when Rambutan will be available?
Think the Luma has no I2S/SPDIF outputs...

Well this topic went totally off-topic (o;

Anyway...ordered some NXP I2C2UART chips as well as some LinkIt Smart 7688 modules for testing...thanks for the link :-)

The LinkIt Smart 7688 might be also a good alternative for our hundreds/thousand of Carambola2 modules for future products...


I consider this thread as closed :-)
