A38X ClearFog


Discover the endless potential of the powerful ARM based boards of ClearFog. The family includes the ClearFog Pro and ClearFog Base (coming soon). Harnessing the robust processing abilities of the ARMADA 38x SoC from Marvell, the ClearFog offers vast application potential as a flexible development board or a ready to deploy solution. Alongside the powerful ARMADA 38x SoC, the ClearFog includes a variety of I/O and connectivity technologies such as multiple mini-PCIe/mSATA sockets, audio/telephony module header, PoE expansion header, mikroBUS™ – a simple socket allowing you to integrate a wide range of MikroElektronika click boards™ modular extensions.

Sometimes there is an easy solution to still use the given clickboard. This is a solution for OLED C: The INT pin on the mikrobus header is not used by clickboard, so one just needs to solder a little wire bridging INT with AN onto the clickboard. And make sure to adapt all code to the new pin!

Accessing GPIO Pins

This is an example code for accessing the GPIOs on the Clearfog:

Example for gpio 22

cd /sys/class/gpio/ 
echo 22 > export 
cd gpio22/ 
echo out > direction 
echo 0 > value
