== Connectors pinout ==
<section begin=CPU/>
=== J1,J2 and J3 ===
The pinout of the J1, J2 and J3 connectors of the Bora Xpress EVB is the same of the [[Pinout (BORAXpress)BORA_Xpress_SOM/BORA_Xpress_Hardware/Pinout_Table#Connectors_description|counterpart connectors on BORA Xpress module]].<section end=CPU/><section begin=Power Supply/>

<section end=Boot Configurations/>
<section begin=Watchdog/>
=== WatchDog Settings - S1, S2 and S3 ===
S1, S2 and S3 are dip-switch to override the default startup delay and timeout of the BORA Xpress module watchdog.
For more details please refer to [[BORA_Xpress_SOM/BORA_Xpress_Hardware/Peripherals/Watchdog (BORAXpress)|this page]].

=== DWM (DAVE Wifi/BT module) socket - J23 ===
J23 is a 52991-0308 connector type (30 pins, vertical, 0.50mm picth). This socket connects the [[Wireless_Module_(DWM) DWM_ADD-ON | DWM Wireless Module]] (optional) to the BORA Xpress EVB. The following table reports the pinout of the connector:

<section begin=CAN/>
=== CAN - J24 ===
J24 is a 10-pin 5x2x2.54mm pitch vertical header directly connected to BORA Xpress SoM's transceiver for the CAN interface. This 2.5mm-pitch header is compatible with commonly available IDC-10/DB9 flat cables. The following table reports the pinout of the connector:

===JP27, JP27 and JP28===
These connectors allow to select power voltage of PL's I/O banks. For more details please refer to [[#PL's I/O voltage selections|this section]].
==PL's I/O voltage selections==
<section begin=Voltage selections/>
PL's I/O banks voltage can be selected via configuration jumpers. It is worth remembering that:
*'''each bank must be powered even if none of its I/Os is used'''
# Jumper on 9-10 -> adds 100mV to VDDIO_BANK35
{{ImportantMessage|text=Please note that by default VDDIO_BANK35 is supplied by VADJ Regulator.For using a dedicated VDDIO_BANK35, it is required to remove R343 and mount R344: check BORA Xpress Evaluation Kit schematics page 10.<br>Then, check and/or properly configure JP27 for selecting the required VDDIO_BANK35}}
===== Bank 34 and VADJ VDDIO selection connector (JP28) =====
The default configuration is:
# Jumper on 5-6 -> supply VADJ with 1.8V
