1.3.2.4 SAMD20 Xplained Pro
The following picture shows the SAMD20 Xplained Pro board connected to PL460-EK expansion board:
PL460-EK is connected to XPRO Interface connector (EXT1) of SAMD20 Xplained Pro. A 15V DC jack must be plugged into PL460-EK in order to supply the power for PLC transmission. For more information about PL460-EK refer to its user guide.
PVdd Monitor functionality on this platform requires a change in resistors on PL460-EK to
meet expected voltage levels at ADC input of SAMD20. For such reason, PVdd Monitor is
disabled by means of APP_PLC_DISABLE_PVDDMON macro definition.
The proper resistor values are already configured on MCC for provided projects.
The USB connector of SAMD20 Xplained Pro can be used to:
- Manage the PLC PHY Tx Test Console. UART baud-rate is configured at 115200 bps (it can’t be higher due to hardware limitations on this board).
- Flash/debug the SAMD20 device with the on-board Jlink debugger
