SUPPORT & DOCUMENTATION
We fixed the email issue, sorry for that !
Best start is at following address >https://docs.ipi.wiki/iot_pi/
And for a full LEC-PX30 manual you will be served from here > https://www.adlinktech.com/Products/Computer_on_Modules/SMARC/LEC-PX30?lang=en
As a reminder the PX30 module on top of the board is fully SMARC-2.1 compliant
Let us know if this helped you move forward
Many thanks to Henri Parmentier
