Table 7 Inputs and Outputs
A load connected to a digital output pin DO1 may draw significant current. In case digital output are
used in a user application, it is strongly suggested to power the device from
an external power supply
and not over USB. Otherwise, USB power limits might be exceeded.

USB
Micro-USB connector (X4) uses the standard pinout, and can be used for firmware upload or
in application as a virtual COM port.

Galvanic Isolation
The device does
not
have any galvanic isolation. The user has to make sure there are no ground loop
in his setup
