Nucleo 144 - Pins¶

Pin diagrams¶

Pin diagrams of Zio headers are edited to include Arduino style pin numbers.
These are F429ZI/F439ZI; F446ZE and F413ZH are quite similar. Refer to varaint files to confirm.

8 District PCB¶

This is a prototype/development board - - almost plug-n-play, once the headers and other components are soldered. Motor shields are installed without modifications.

Add custom motor define in config.h
Example shows two EX8874 and two L298 motor shields
