Additional GNDs
The EasyPIC v8 development board contains exposed GND (8) pins which can be
used to connect measurement or testing equipment. These additional GND pins
allow secure connection with the instrumentation probes, avoiding loose cables or
unreliable contacts that might compromise the accuracy of the readings.
