## Summary
|
|
|
|
|
|
|
|
The BaseBoard is a DPP Application platform based on the Colibri Arm System on Module (SoM) family from Toradex. It enables to run a full-fledged Linux distribution, direct integration/usage of all DPP Communication boards and integrates a multitude of sensors. It has been designed to facilitate low-power operating modes.
