PNEV5190B evaluation board quick start guide
J4: open
J5: open
J6: open
J13: open (this jumper can be used to bypass the DC-DC, but only if the EEPROM
settings are done properly AND the required board modifications are made properly)
J14: open
J8 can be used to measure the current consumption of the TX driver circuit including the
DC-DC.
J12 can be used to measure the supply current consumption, excluding the TX driver
part.

3.2.3 PNEV5190M module board
The PNEV5190M module board is shown in
the most relevant components, directly connected to the PN5190, i.e. the EMC filter
inductors, the DC-DC inductor, the major block capacitors and the 27.12 MHz crystal.
The default clock is based on this 27.12 MHz crystal, but the board supports the option to
test external clock input, if needed.
