+The phyNODE evaluation board consists of a [phyWAVE](https://www.phytec.de/produkte/internet-of-things/phywave/)
+module mounted on a common PCB with several sensor and actuator modules.
+The board provides 2 USB ports. The one next to the white imprint *cmsis-dap*
+is meant for development (debug and flash). The second one, next to the golden
+*PHYTEC* imprint, is connected to the USB peripheral of the MCU and may be used
+by a firmware (currently not supported).
+
+
 The implementation status of the phyWAVE and phyNODE peripherals are listed
 below. You can find links to the corresponding Pull Requests which may give you
 a code reference.

-### Details
-The PCB-pieces with the mounted sensors can be separated from the evaluation
-board to capture sensor values from specific spatial points.

-### Pinout Reference
+## Pinout Reference
 
 The board features an Arduino like header connector to mount shields. The
 spacing of the 4 pin rows is a bit offset, thus shields might not fit perfectly.
