1.2.2 Grounding
To avoid damaging the sensitive electronic components in the Micro-JLT GNSS™ GNSDO always
make sure to discharge any built-up electrostatic charge to a good ground source, such as power
supply ground. This should be done before handling the circuit board or anything connected to it, i.e.
the GNSS antenna.
