Probe Hooks
Probe hooks are available around the board to ease connection of instruments for measurement of
supplies when debugging. At the separation line between the microcontroller section on the left and
the driver section on the right lies a header pins connector. This connector allows to probe supply levels
and SPI communication digital.

Digital GPIOs
General-purpose inputs and outputs (GPIOs) are provided to ease integration of the development kit in
a prototype. For example, digital inputs may be used as trigger inputs to fire the waveforms or to send
information from the system to the development kit. Four pins can be configured as input or output.
Using these GPIOs implies to modify the firmware to support them. However, they are already
physically implemented and routed to the MCU. They need to be activated in the firmware software
code project.
